Events

January

• During the month, the Government of Italy gives permission for armed U.S. unmanned aerial vehicles (UAVs) to fly strike missions from Naval Air Station Sigonella on Sicily - where the United States has based unarmed surveillance UAVs since 2001 - against Islamic State targets in Libya, but only if they are "defensive," meaning that they are flown to protect U.S. special operations forces operating in and near Libya or rescuers attempting to retrieve downed U.S. pilots. Italy continues to prohibit U.S. offensive strikes from Italian territory, and also reserves to itself the right to veto any U.S. mission.

2 January

• Indian aerial surveillance platforms detect a group of gunmen entering an Indian Air Force base at Pathankot, India, and Indian Air Force security forces exchange fire with them in a housing area. Four of the gunmen and two Indian Air Force security personnel are killed. Gunfire erupts again two hours later, and Indian helicopters fire on gunmen in the base later in the day. Indian security forces finally declare the base secure in the late afternoon, 14 hours after the intrusion began.

3 January

• Combat again breaks out at India's air base at Pathankot after security forces discover two militants still hiding on the base. Security forces reportedly kill the militants.
• An official at the United States Embassy in Addis Ababa announces that by mutual agreement with the Government of Ethiopia the United States had shut down its military unmanned aerial vehicle base at Arba Minch Airport in Arba Minch in southern Ethiopia in September 2015. The two countries had agreed that the base, which had opened in 2011, was no longer necessary. It is the first public announcement that the base had been closed.

4 January

• Saudi Arabia's civil aviation authority suspends all civilian flights between Saudi Arabia and Iran. The move, which comes a day after Saudi Arabia severed diplomatic relations with Iran, raises doubts about the future ability of Islamic pilgrims from Iran to visit Mecca and of Shiite pilgrims from Saudi Arabia to visit religious sites in Iran.
• John Boggs files suit against William Merideth for shooting down his unmanned aerial vehicle (UAV) in Bullitt County, Kentucky, with a shotgun as the UAV hovered over Merideth's property, asserting that the drone was in public airspace when it was shot down and requesting $1,800 in damages and clarification as to how high above private property public airspace begins. Merideth had claimed the UAV was spying on his family and violating his privacy. The case promises to spur the U.S. judicial system to clarify where private property rights end and federal jurisdiction begins in U.S. airspace, with a significant potential impact on future private and commercial UAV operations.

5 January

• When two United States Air Force Sikorsky HH-60 Pave Hawk helicopters attempt to evacuate wounded Afghan military personnel near Marjah, Afghanistan, one strikes a wall and is disabled and the other is ordered to abort the mission under heavy ground fire. One American is killed and two wounded in the incident; they are the first U.S. casualties in Afghanistan in 2016.

7 January

• Iran claims that an airstrike by the Saudi-led coalition operating against rebel forces in Yemen struck its embassy in Sana'a overnight. Local residents and press observers report no signs of damage at the embassy.
• A report by the inspector general of the United States Department of Transportation to the U.S. Federal Aviation Administration (FAA) expresses a concern that airline pilots have become so reliant on automation technology to fly their aircraft that they have lost the skills necessary to take manual control of an airliner in order to deal promptly and effectively with unforeseen events. The FAA responds that it will require enhancements in pilot training for the manual flight of aircraft, and the Air Line Pilots Association endorses the need for well-trained aircrew aboard airliners.

8 January

• West Air Sweden Flight 294, a Canadair CL-600-2B19 Regional Jet CRJ-200PF (registration SE-DUX) on a domestic cargo flight in Norway carrying mail and packages from Oslo to Tromsø, suddenly goes into a steep descent after a brief Mayday call and crashes near Akkajaure, Sweden, killing its crew of two.

9 January

• Four air-to-ground missiles launched by Russian Federation Air Force aircraft hit a building used as a court house and prison by the Nusra Front in Maarrat al-Nu'man in Syria's Idlib Governorate. The strike kills at least 57 people, including 23 Nusra Front members.
• Tracey Curtis-Taylor completes a solo flight from Farnborough Airport in Farnborough, England, to Sydney, Australia, in the Boeing-Stearman Model 75 open-cockpit biplane Spirit of Artemis. During the 100-day, 13,000-mile (21,000-kilometer) flight, begun on 1 October 2015, she has flown over 23 countries and made 50 refueling stops. The flight recreates the 1930 Croydon-to-Darwin flight of Amy Johnson, the first solo flight between the United Kingdom and Australia by a woman.

10 January

• As a show of force after a 6 January nuclear weapons test by North Korea, a Guam-based U.S. Air Force B-52H Stratofortress flies to South Korea, where it circles over Osan Air Base flanked by a U.S. Air Force F-16 Fighting Falcon and a Republic of Korea Air Force F-15 Eagle before returning to Guam.

12 January

• An unarmed Iranian unmanned aerial vehicle flies near the French Navy aircraft carrier Charles de Gaulle and directly over the United States Navy aircraft carrier USS Harry S Truman (CVN-75) as they operate in international waters in the Persian Gulf. Iran will announce the flight and release purported video from it on 29 January - implying that the video had been taken earlier that day rather than on 12 January - and a United States Fifth Fleet spokesman will respond by calling the flight "abnormal and unprofessional."
• An air-and-bus bridge begins operating as a pilot program to help 8,000 Cuban immigrants stranded in Costa Rica since Nicaragua closed its border to them on 13 November 2015 by allowing them to fly out of Costa Rica and reach Mexico, from which they can emigrate to the United States. The first flight of the air-and-bus bridge departs Liberia, Costa Rica, during the evening as part of regional agreement to help the Cubans bypass Nicaragua.

13 January

• An Israeli Air Force aircraft strikes a group of Palestinians - members of the Al-Aqsa Martyrs Brigade - on a beach in the northern Gaza Strip near the Israeli border fence, killing one and injuring three others. The Israel Defense Force claims that they were planting explosives with which to target Israeli soldiers patrolling the border on the other side of the fence.

14 January

• Air France officially retires the Boeing 747 from its fleet with Flight 744, a scenic flight by a Boeing 747-400 with 432 people on board, including 380 paying passengers, in formation with 12 Dassault/Dornier Alpha Jets of the French Air Force's Patrouille de France aerobatic team. The airliner takes off from Charles de Gaulle Airport in Paris and makes a clockwise circuit that takes it over Lyon, Geneva, Marseille, Montpellier, Bordeaux, and Deauville before returning to Charles de Gaulle Airport, offering passengers scenic views of Mont Blanc, Normandy, and Mont Saint-Michel along the way. The Boeing 747 had been part of the Air France fleet since 1974 and the 68 Boeing 747s the airline had operated had carried 250 million passengers. In the future plans to use its Airbus A380s and Boeing 777s for long-haul flights.
• Two United States Marine Corps Sikorsky CH-53 Sea Stallion helicopters of Marine Heavy Helicopter Squadron 463 (HMH-463), each carrying six Marines, collide and crash in a fireball late in the evening over the Pacific Ocean north of Oahu just off Haleiwa, Hawaii, and crash, leaving all 12 Marines missing. The United States Coast Guard will call off the search for the Marines on 19 January, and the Marine Corps officially will declare them dead on 20 January.

15 January

• A late-evening U.S. unmanned aerial vehicle-launched air-to-ground missile strike kills three suspected al-Qaeda in the Arabian Peninsula members as they drive in a car in Yemen's Shabwa Governorate.
• SpaceX successfully fires the engines of the first stage of Falcon 9 rocket it had used to launch a satellite into orbit and then landed successfully on land in December 2015, the first time in a history a rocket stage had made a soft, controlled landing. The firing of the engines demonstrates the feasibility of reusing the rocket stage, an important step in the development of reusable rockets that make space launches less expensive.

16 January

• Speaking at the conclusion of a missile exercise at Skwierzyna, Poland, involving U.S. and Polish military forces, Polish Minister of National Defense Antoni Macierewicz says that the Government of Poland wants a permanent presence of North Atlantic Treaty Organization (NATO) and U.S. military forces in Poland, including MIM-104 Patriot surface-to-air missiles.

17 January

• After successfully launching the Jason-3 satellite into orbit from Vandenberg Air Force Base in California, the first stage of a SpaceX Falcon 9 rocket touches down on a landing platform in the Pacific Ocean 200 miles (322 km) off California softly enough to land successfully, but topples over when of its landing legs fails to lock in place and collapses. It is SpaceX's third attempt to land a Falcon 9 first stage at sea; the two previous attempts, both in 2015, also had been unsuccessful, although SpaceX had made history's first successful landing of a reusable rocket stage - also of a Falcon 9 - on land in December 2015.
• Just before midnight, aircraft of the Saudi-led coalition strike a police facility in Sana'a, Yemen, used by both security forces and the Houthi rebels as an assembly point, killing 26 people and injuring 15. The dead and wounded are all policemen and Houthi rebels.

21 January

• An air strike by the Saudi-led coalition against a rebel-held facility at Ras Isa on Yemen's Red Sea coast used to load tanker trucks with refined petroleum products for distribution in rebel-held areas of Yemen destroys trucks and starts a large fire, killing at least nine and perhaps as many as 16 people and injuring at least 30.

22 January

• Aircraft of the Saudi-led coalition strike targets across Yemen, killing dozens of people. Houthi rebels in Saada Governorate report that the strikes kill 26 people in Dahyan, including the driver of a Doctors Without Borders ambulance. Strikes against rebel weapon depots on the mountain of Nahdeen kill another 22 people, and strikes in Hodeida targeting trucks carrying smugged oil from the port there to rebel forces kill another 10 people. Strikes also target gatherings of Houthis and rebel Yemeni Army units allied with them in Al Jawf Governorate, Dhamar, ad Taiz.
• The United States Fish and Wildlife Service announces that after the 2016 season it will end its support of the use of ultralight aircraft to lead whooping cranes on their migration from Wisconsin to the Florida Gulf Coast each autumn in Operation Migration. A conclusion by experts in whooping crane biology that human intervention such as ultralight flights impairs the ability of the cranes to learn the parenting skills necessary to raise chicks in the wild prompts the decision to end support.

23 January

• Air raids on Islamic State-held Khasham in Syria's Deir ez-Zor Governorate kill 47 people. Observers in Syria suspect Russian aircraft of having conducted the raids.

26 January

• A month-long Syrian government military campaign results in the seizure of the crossroads at Sheikh Miskeen, Syria, from rebel forces. Russian airstrikes have played a conspicuous role in the success of the campaign.
• The United States Department of the Treasury announces the lifting of major U.S. trade and travel restrictions on Cuba. The new regulations allow code sharing between U.S. and Cuban airlines, airplane-leasing deals in the United States for Cuba, and permission for U.S. airline crews to travel to Cuba.

28 January

• Iran agrees to buy 118 airliners - 73 wide-body and 45 narrow-body - from Airbus in a deal worth $27,000,000,000. The purchase consists of 12 A380, 16 A350-1000, 45 A330, and 45 A320-family aircraft. The deal is contingent on Airbus receiving export licenses from the United States, where 10 percent of parts for Airbus aircraft are manufactured. Iran, which first plans to focus on expansion of its airports and more urgent civil aviation needs, does not plan to take delivery of the airliners until ca. 2020.

29 January

• Turkey claims a Russian Federation Air Force Sukhoi Su-34 (NATO reporting name "Fullback") has violated its airspace near the border with Syria during the day, warning Russia of consequences if any further violations take place. A Russian Ministry of Defense spokesman denies any Russian intrusion into Turkey's airspace; he asserts that Turkish radar installations are incapable of identifying a particular aircraft's type or nationality and that no Russian pilot had received a verbal warning in either English or Russian, and he dismisses the Turkish claim as "pure propaganda."

February

1 February

• Two evening airstrikes by U.S. aircraft operating as part of the North Atlantic Treaty Organization (NATO) intervention in Afghanistan level the Islamic State of Afghanistan "Voice of the Caliphate" radio station, knocking it off the air during its nightly illegal propaganda broadcast from Nangarhar Province's Achin District. The strikes combined with Afghan Army ground operations kill 29 Islamic State supporters, including eight who worked for the radio station and an associated Internet operation.

2 February

• Daallo Airlines Flight 159, an Airbus A321-100 (registration SX-BHS) with 81 people on board flying from Mogadishu, Somalia, to Djibouti City, Djibouti, experiences an explosion which sets one passenger on fire and blows a hole in the fuselage, through which the burning passenger is sucked from the plane at an altitude of 14,000 feet (4,267 meters). The airliner returns to Mogadishu and lands safely. The burned body of the man sucked from the plane is found near Balad, Somalia; two other people on board the plane suffer minor injuries.

4 February

• Russian aircraft support a Syrian government ground offensive which cuts a key rebel supply route to Aleppo. In what Syrian rebel fighters describe as one of the most intense periods of Russian airstrikes since the Russian air campaign in Syria began, Russian aircraft conduct 200 strikes over a 24-hour period.

7 February

• A strike by unidentified aircraft hits a medical technology college in Derna, Libya, killing four people. The area is held by a coalition of Islamic militant groups who have been defending it from the Islamic State.

8 February

• Prime Minister of Canada Justin Trudeau announces that Canada will withdraw its six CF-18 Hornets from bombing missions against the Islamic State within two weeks, but will extend its non-combat air support to the U.S.-led air campaign against the Islamic State until 31 March 2017, using one CC-150 Polaris aerial refueling aircraft and up to two CP-140 Aurora reconnaissance planes.
• Talking to the media in Ankara, Turkey, after holding discussions about the European migrant crisis, Chancellor of Germany Angela Merkel says that she is "not just appalled, but horrified" at the suffering cause by airstrikes - particularly Russian airstrikes - in Syria, while Prime Minister of Turkey Ahmet Davutoglu says that "No one should excuse or show tolerance toward the Russian air attacks that amount to ethnic massacres by saying 'Turkey takes care of the Syrian refugees anyway.'"
• A panel of the International Civil Aviation Organization proposes history's first worldwide standards for carbon dioxide emissions for aircraft; the standards would apply to all new aircraft designs beginning in 2020 and to all newly delivered aircraft beginning in 2023. Environmental groups criticize the standard for not addressing emissions by existing aircraft or new aircraft designed before 2020 or delivered before 2023.

9 February

• Testifying before a United States Senate committee, U.S. intelligence officials report that the Russian air campaign in Syria has turned the tide in the Syrian Civil War and made it more likely that the regime of Bashar al-Assad will remain in power.

10 February

• Airstrikes in Syria near Aleppo hit two hospitals. The U.S.-led coalition blames Russia for the strike; Russia responds by blaming the United States, which in turn announces that the U.S.-led coalition made no strikes in the area during the day.
• During a flight from Punta Cana in the Dominican Republic to Moscow with 355 passengers on board, an Orenair Boeing 777-200 (registration VP-BHB) experiences an engine failure and smoke in the cabin. The crew shuts down the malfunctioning engine, the smoke ceases, and the aircraft performs an emergency landing in Punta Cana during which a tire bursts and sparks appear. The passengers and crew evacuate via evacuation slides with no injuries.
• The president of the National Air Traffic Controllers Association (NATCA), Paul Rinaldi, tells the United States House Committee on Transportation and Infrastructure that NATCA supports a United States House bill that would create a federally chartered corporation to operate the air traffic control system in the United States and transfer 38,000 U.S. federal government workers, including 14,000 NATCA air traffic controllers who work for the U.S. Federal Aviation Administration, to the new corporation.

11 February

• At meetings in Munich, Germany, a group of 17 countries including Iran, Russia, Saudi Arabia, and the United States agree to a "cessation of hostilities" in the Syrian Civil War that is to take effect by 18 February. Under the agreement, Russia projects that it will cease airstrikes in Syria on 18 February except for strikes against the Islamic State and Jabhat al-Nusra, which it will continue, although it also ambiguously reserves to right strike any groups it deems "terrorists;" the agreement also includes humanitarian air drops of supplies in Syria that are expected to begin as early as 13-14 February, with Russia planning to use its aircraft to drop supplies in seven locations in Syria. After the agreement takes effect, a task force of countries headed by Russia and the United States is to establish geographic and other limits on airstrikes in Syria, adjudicate differences of opinion about which targets remain legitimate for airstrikes, and select targets for airstrikes, the first time the United States has agreed o do more than "deconflict" its air operations over Syria with those of Russia. Neither the Government of Syria or any of the rebel groups fighting against it take part in the meetings or are parties to the agreement.

12 February

• Syrian government and Russian aircraft strike targets in rebel areas in many locations across Syria, including targets north of Aleppo in support of a 10-day-old Syrian government ground offensive seeking to surround and cut off rebel-held Aleppo.

15 February

• Aircraft hit at least two schools and four hospitals in northern Syria with air-to-ground missiles, killing nearly 50 people. Russia responds to reports that its aircraft were responsible by blaming the United States for the strikes, as does the Government of Syria. The United States responds that no aircraft of the U.S.-led coalition was operating in the area at the time.
• Villagers and rebel forces in southwestern Somalia claim that a U.S. unmanned aerial vehicle (UAV) has crashed in a village there. The United States responds that all of its UAVs have returned safely from their missions and are accounted for.

17-18 February

• Turkish Air Force jets bomb Kurdish camps in northern Iraq hours after a suicide car bomb killed 28 people in Ankara, Turkey, on 17 February.

18 February

• The United States Government grants Boeing a license allowing the company to enter into talks with airlines in Iran about sales of airliners. Iran's aging airliner fleet and lack of Boeing 777s raises the possibility of significant sales for Boeing, although the company will require additional approval from the United States Government ensuring the legitimacy of any transactions before actually selling Iran any aircraft.

19 February

• Flying from bases in the United Kingdom, United States Air Force F-15 Eagles strike an Islamic State camp on the outskirts of Sabratha, Libya, killing Islamic State leader Noureddine Chouchane and 48 other Islamic State personnel.
• A deadline established on 12 February for a "cessation of hostilities" in Syria except for strikes against those targets mutually agreed to by Russia and the U.S.-led coalition passes without the ceasefire going into effect. Russia and the U.S.-led coalition have been unable to agree on what constitutes a "terrorist" target, with Russia taking the view that all groups opposing the Syrian government are terrorists and the U.S.-led coalition limiting the definition of terrorists in Syria to the Islamic State and Jabhat al-Nusra, leading to problems in determining which areas of Syria will be subject to Russian and U.S.-led coalition airstrikes after the "cessation of hostilities" begins; Turkey's insistence on targeting Kurdish forces in Syria adds to the disagreement over legitimate targets.
• In a ceremony in a hangar in Mojave, California, Sir Richard Branson unveils Virgin Galactic's new VSS Unity, a SpaceShipTwo-class rocket-powered suborbital spaceplane.

20 February

• The Government of Serbia claims that the 19 February U.S. airstrike in Sabratha, Libya, killed two Serbian diplomats. The United States Department of Defense responds that it does not believe the Serbians were at the targeted location during the airstrike and that the condition of their bodies is inconsistent with death in the airstrike.
• A day after the United Nations Security Council rejected a Russian draft resolution calling for an immediate end to Turkey's shelling of and other military actions against Syria, Russia's Ministry of Defense announces that five additional Russian Federation Air Force Mikoyan MiG-29 (NATO reporting name "Fulcrum") fighters and a Mil Mi-8MT (NATO reporting name "Hip") helicopter have arrived at a military base outside Yerevan, Armenia, and soon will be sent to Erebuni Airport outside Yerevan - only 40 km (25 miles) from the Turkish border - to reinforce the 18 MiG-29s and seven Mil Mi-24P (NATO reporting name "Hind") attack helicopters already based there. After assembly, the additional aircraft are expected to begin practice flights from Erebuni Airport in mid-March.

21 February

• British Royal Navy test pilot Eric "Winkle" Brown dies at the age of 97 at East Surrey Hospital in Redhill, England. Surviving 11 plane crashes and the 1941 sinking of the escort aircraft carrier HMS Audacity (D10), he is credited with flying 487 different types of aircraft, more than anyone else in history, and with making 2,407 aircraft carrier landings, also a world record, as well as with making the first carrier landing in history, landing a de Havilland Sea Vampire aboard HMS Ocean (R68) in 1945. Although he had retired in 1970, he had continued flying until 1994.

22 February

• The United States and Russia announce that they have agreed on a partial ceasefire in Syria under which they will establish a "hotline" which they will use to share informnation allowing them to delineate the boundaries of areas controlled by specific groups in Syria. They also agree to limit airstrikes to areas controlled by the Islamic State, Jabhat al-Nusra, or any other group that the United Nations designates as a terrorist group. Other rebel groups in Syria and the Government of Syria have until 26 February to inform the United States or Russia that they agree to the terms of the ceasefire; if they do not, they run the risk of coming under renewed air attack by Russia or the U.S.-led coalition.
• Russia requests permission to fly surveillance flights over the United States under the Treaty on Open Skies using Tupolev Tu-154 (NATO reporting name "Careless") aircraft equipped with new, high-powered digital cameras. The request prompts a debate within the United States Government over whether it is a small concession worth making in order to keep the treaty viable or a violation of the spirit of the treaty that would allow surveillance unintended when the treaty was signed in 1992. The treaty, signed by 34 countries, has been in force since 2002.

24 February

• Tara Air Flight 193, a de Havilland Canada DHC-6 Twin Otter on a domestic flight in Nepal from Pokhara Airport in Pokhara to Jomsom Airport in Jomsom, crashes and burns near Dana in Myagdi District ten minutes after take off, killing all 23 people on board.

• A few minutes after a final Russian airstrike hits Kafr Hamrah, a ceasefire goes into effect in the Syrian Civil War. Under its terms, the U.S.-led coalition is to continue airstrikes against the Islamic State and the Russian Federation Air Force is to continue to hit both Islamic State and Jabhat al-Nusra targets, with the United States and Russia coordinating their understanding of the boundaries of territories held by the two groups so that strikes do not occur against any of the other groups in Syria unless they have been declared terrorist groups by the United Nations.
• Solar Impulse 2, grounded at Kalaeloa Airport in Kalealoa, Hawaii, since 3 July 2015 due to battery damage caused by overheating during its attempt to become the first manned solar-powered aircraft to circumnavigate the Earth, makes it first test flight after repairs. Taking off from Kalealoa Airport, Solar Impulse 2 flies over the Pacific Ocean for 90 minutes, reaching an altitude of 8,000 feet (2,438 meters) before returning. The Solar Impulse team plans to resume the circumnavigation in late April 2016 with a flight from Hawaii to Phoenix, Arizona.

27 February

• Airstrikes attributed to the Saudi-led coalition targeting advancing rebel forces hit a market area in the Nehm region outside Sana'a, Yemen, killing at least 30 people and injuring at least 30 more.
• Russia announces a 24-hour cessation of all Russian airstrikes in Syria, reserving the right to continue airstrikes targeting the Islamic State and Jabhat al-Nusra.

28 February

• On the second day of a planned two-week cessation of airstrikes in Syria, Russian aircraft based in northwestern Syria resume strikes in Syria, hitting six towns and villages in Aleppo, Hama, and Idib Governorates.

29 February

• An American tourist turns over to authorities in Mozambique what appears to be part of the skin of a Boeing 777 horizontal stabilizer found over the preceding weekend on a sandbar in the Indian Ocean just off the country's coast, raising expectations that it will turn out to be debris from Malaysian Airlines Flight 370, a Boeing 777 missing since 8 March 2014.
• In the United States, the National Aeronautics and Space Administration (NASA) announces that it has awarded a $20 million contract to Lockheed Martin to develop a quiet supersonic demonstration passenger aircraft using Quiet Supersonic Technology (QueSST). NASA hopes that the new technology, which allows aircraft flying at supersonic speeds to make only a soft thump instead of a loud and damaging sonic boom, will prompt the development of a new generation of "low-boom" supersonic transports that can fly over populated areas at supersonic speeds.
• The United States has conducted 135 airstrikes in Yemen since its air campaign there began, five of them since 1 January. The strikes have killed more that 650 al-Qaeda in the Arabian Peninsula personnel and 105 civilians.

He turns it in to authorities the following day, raising hopes that it is also from Flight 370, missing since 8 March 2014.

4 March

• In a sudden change of policy, Prime Minister of Japan Shinzo Abe agrees to suspend construction of a United States Marine Corps air station at Henoko Bay, Okinawa, and settle out of court on three lawsuits related to its construction. However, he also says that he remains committed to closing Marine Corps Air Station Futenma, Okinawa, and moving its operations elsewhere and that Henoko Bay is the only practical alternative.
• A series of airstrikes by U.S. manned aircraft and unmanned aerial vehicles in Shaddadi, Syria, kills 13 Islamic State personnel, likely including Abu Omar al-Shishani.
• Rebel groups in Syria complain that despite the ceasefire in the Syria Civil War - which excludes only groups deemed terrorist groups by the United Nations, notably the Islamic State and Jabhat al-Nusra - that went into effect on 27 February, they are under attack by Syrian government forces supported by airstrikes they believe the Russian Federation Air Force is conducting. One rebel in Latakia Governorate in northwestern Syria claims that his group is "getting bombarded by 50 airstrikes a day by the Russians."
• SpaceX successfully launches a satellite payload into space using an upgraded Falcon 9 rocket, but its attempt to land the rocket's first stage on a floating platform - termed an "autonomous space port droneship" by SpaceX founder Elon Musk - is only partially successful: although the first stage lands on the platform, the landing is too hard for a successful recovery.
• The U.S. National Transportation Safety Board (NTSB) responds to the U.S. Federal Aviation Administration?s (FAA) November 2015 rejection of the NTSB?s April 2014 recommendation that the FAA establish licensing requirements and safety standards for commercial balloon tour operators and make them subject to FAA safety inspections, regulating them in a manner similar to the way it regulates commercial airplane and helicopter tour operators. In its response, the NTSB informs the FAA that it finds the rejection unacceptable and that its recommendation remains open.

• African Parks Network announces that the remains of its employee, American anti-poaching pilot Bill Fitzpatrick, have been recovered from a crash site in Cameroon. Fiztpatrick had disappeared on 22 June 2014 during a flight to a job in Odzala-Kokoua National Park in the Republic of the Congo. Local residents had discovered the wreckage of Fitzpatrick's plane in April 2015, but the remote site and dense vegetation in the area had made it difficult for helicopters to land there and bureaucratic procedures of the Government of Cameroon also had delayed the recovery of Fitzpatrick's remains.
• Boeing announces that it has filed a patent for a self-cleaning airplane lavatory which can sanitize itself in three seconds using far-ultraviolet light. The lavatory also features a hands-free faucet, soap dispenser, trash flap, toilet lid, toilet seat, and hand dryer, and Boeing reports that it also is designing a hands-free door latch and is studying the design of a hands-free system to lift and close the toilet seat so that all surfaces are exposed to the far-ultraviolet light during the cleaning cycle. Once Boeing offers the new lavatories to customers, it is expected to take years for airlines to update their fleets with them.

8 March

• U.S. Special Operations Forces conduct a joint U.S.-Somali helicopter raid against al-Shabaab in Somalia. The United States Department of Defense announces that U.S. forces play only an advisory role and do not accompany the Somali forces on the raid, although the helicopters employed are U.S military helicopters flown by U.S. crews.

9 March

• A True Aviation Antonov An-26 cargo plane (registration S2-AGZ) carrying a cargo of shrimp suffers the failure of an engine shortly after takeoff from Cox's Bazar Airport in Cox's Bazar, Bangladesh, and crashes into the Bay of Bengal five minutes after takeoff while attempting to return to the airport, killing three of the four people on board and critically injuring the only survivor.
• Amazon.com announces that it has agreed to lease 20 Boeing 767-300 cargo aircraft from Air Transport Services Group as a first step toward operating its own fleet of planes, part of a larger effort to reduce its shipping costs and its reliance on FedEx and the United Parcel Service.

• United States Secretary of State John Kerry meets in Moscow with President of Russia Vladimir Putin to discuss a U.S. proposal supported by senior United Nations officials to "integrate" U.S. and Russian air operations against Islamic State and Jabhat al-Nusra targets in Syria and halt Syrian government and Russian air attacks against civilians and moderate Syrian rebel forces that are parties to a widely violated February 2016 ceasefire agreement. The proposal calls for Russia to pressure the Syrian government to ground all Syrian military aircraft and restrict Russian airstrikes to Islamic State and Jabhat al-Nusra targets, and for U.S. airstrikes against Jabhat al-Nusra - previously conducted only rarely to avoid direct U.S. involvement in the Syrian Civil War - to expand alongside strikes against Islamic State targets in Syria. Under the proposal, Russia and the United States - via a Joint Implementation Group headquartered in Amman, Jordan - would share intelligence and strike planning for Jabhat al-Nusra leadership targets, headquarters, training camps, logistical depots, and supply lines, with other areas off-limits to airstrikes by either country, and a "liaison body" would ensure that Russia and the United States inform one another at least a day in advance of planned strikes against agreed-upon targets. The proposal calls for implementation of an agreement by 31 July. The following day, Kerry and Foreign Minister of Russia Sergei Lavrov announce after day-long talks that the two countries have reached an agreement that could reduce civilian casualties and improve targeting of terrorist groups, but they reveal no details to the public.
• Airbus and Boeing experience their lowest airliner sales totals at the Farnborough Air Show in six years, securing deals for about 400 aircraft worth about $50,000,000,000, only half their sales at the previous year?s show. American, European, and Persian Gulf carriers make almost no deals, and only carriers in Asia make large orders. No orders materialize for the Boeing 777, Airbus A330neo, or Bombardier C-Series, and Airbus A380 production rates are greatly reduced. Industry analysts blame the reduced sales on uncertainty over the future of the global economy and on the United Kingdom?s 23 June 2016 vote to leave the European Union, popularly known as the "Brexit."

• The U.S.-led coalition strikes Islamic State-held territory in northern Syria to help counter an Islamic State ground offensive against the U.S.-backed Syrian Democratic Forces (SDF). According to the Syrian Observatory for Human Rights, 56 civilians die in the strikes, while other reports put the death toll as high as 212; for example, the Islamic State claims that U.S. strikes kill 160 civilians in Tokhar, and the Syrian Ministry of Foreign Affairs and Expatriates claims a strike by French aircraft against Tokhar kills 120 civilians. An SDF spokesman disputes the claims of civilian deaths, saying that the strikes have killed large numbers of Islamic State personnel, and that the Islamic State has simply buried them quickly and falsely claimed that civilian deaths have occurred. The U.S. military announces that U.S. aircraft have conducted 18 strikes in the Manbij area over the previous 24 hours - out of 450 in the area since May - and that it is launching an investigation to determine whether the allegations of civilian casualties are true. By late August, United States Central Command will report that it has concluded that the Tokhar strike - conducted by U.S. Air Force A-10 Thunderbolt II and B-52H Stratofortress aircraft using 500-pound (227-kg) GBU-31 and GBU-54 laser-guided bombs to knock out a mortar position - killed 85 Islamic militants and 10 civilians, while Syrian activists claim that all or most of the 95 dead were civilians.

• According to the International Air Transport Association, commercial air traffic to and from Venezuela has dropped 30 by percent since the Venezuelan bolívar began a steep decline in value in 2013 despite a rapid increase in air travel almost everywhere else in the world. International air carriers have accumulated about $4,000,000,000 in almost worthless bolívars which the Government of Venezuela prohibits them from converting into hard currency, prompting various airlines since 2014 - including Aeroméxico, Air Canada, Alitalia, LATAM, and Lufthansa - to cease service to Venezuela and others to reduce flights or provide service with smaller planes; only Venezuelan airlines are permitted to pay for fuel with bolívars, all other carriers being required to pay in United States dollars. Simón Bolívar International Airport in Caracas, long a major hub for airlines serving South America, has been replaced in that role by airports such as El Dorado International Airport in Bogotá, Colombia, which now handles three times as many passengers as Caracas, and Jorge Chávez International Airport in Callao, Peru, which has enjoyed a 35 percent increase in passengers over the previous two years. Caracas has become so dangerous that Copa Airlines crews are prohibited from leaving their hotel rooms when staying there, massive shipments of cocaine originating in Caracas have been interdicted in the airport?s terminal, and gunfights between police and criminals occur every few months in the airport?s parking lots.

August

• During the month, Delta Air Lines sends a letter of protest to the U.S. General Services Administration, complaining that GSA?s award to JetBlue Airways of the U.S. government contract routes from New York City to Dubai and from New York City to Milan, Italy, in 2015 violates the 1981 Fly America Act - which requires U.S. federal government employees, their families, and federal consultants and contractors to travel aboard U.S. carriers when on official business paid for by the U.S. government - because JetBlue has no aircraft that can fly that far and will book its passengers to those destination on its codeshare partner Emirates, a United Arab Emirates (UAE) airline based in Dubai. Delta joins American Airlines and United Airlines in arguing that they should be selected for such routes to reduce the disadvantage they face when competing with Emirates, the UAE?s Abu Dhabi-based Etihad Airways, and Qatar?s Qatar Airways, all of which receive substantial subsidies from their governments. The GSA responds that JetBlue offers cheaper prices that Delta, American, and United and that its selection does not violate the Fly America Act, regardless of its use of foreign codeshare partners for the routes.

• After the Russian Ministry of Defense claims that a U.S. unmanned aerial vehicle was in the vicinity of the 19 September airstrike on a humanitarian aid convoy and warehouse outside Aleppo, Syria, and implies that it could have conducted the attack, the U.S. Department of Defense responds that no manned or unmanned aircraft of the U.S.-led coalition were in the area at the time. At the U.N. Security Council, U.S. Secretary of State John F. Kerry accuses Moscow of inventing its "own facts" to explain the air attack, which the United States had blamed on the Russian Federation Air Force, adding that "We don't get anywhere by ignoring facts and denying common sense;" he calls for Russia and Syria to "immediately ground all aircraft" flying in areas of northwest Syria where the convoy was hit.

Boeing?s license allows it to sell 80 airliners and lease another 29 new Boeing 737s to Iran.

22 September

• Throughout the day, suspected Syrian Arab Air Force and Russian Federation Air Force aircraft strike targets in rebel-held areas of Aleppo, Syria; twenty-one people die in evening air raids on two Aleppo neighborhoods, and scores have died in airstrikes in the city since 19 September. At the U.N. Security Council, U.S. Secretary of State John F. Kerry repeats his 21 September call for Syria and Russia to ground their aircraft in northeastern Syria, saying that "the only way" for the Syrian ceasefire to succeed is "if the ones who have the air power in this part of the conflict simply stop using it. . . . Absent a major gesture like this, we don't believe there is a point in making more promises, issuing more plans." The U.S. Chairman of the Joint Chiefs of Staff, United States Marine Corps General Joseph Dunford, tells the United States Senate Committee on Armed Services that "I would not agree that coalition aircraft ought to be grounded...I do agree that Syrian regime aircraft and Russian aircraft should be grounded...There's no reason to ground our aircraft...We're not barrel-bombing civilians; we're not causing collateral damage."
• The World Trade Organization (WTO) rules that the European Union, France, Germany, Spain, and the United Kingdom have failed to halt illegal subsidies to Airbus that the WTO had ordered them to stop in 2011 despite reporting in late 2011 that they had done so. The WTO adds that the subsidies - which total $22,000,000,000 over ten years - have cost the economy of the United States tens of billions of dollars and cost Boeing nearly 400 potential airliner sales in 2012 and 2013 alone. The ruling is a sweeping victory for the United States and its aerospace industry, which has disputed European aircraft subsidies for 40 years and first filed a complaint with the WTO about Airbus subsidies in 2004.

23 September

• After the Syrian government announces an offensive against rebel forces in and around Aleppo, Syria, the previous evening, Syrian government aircraft pound rebel-held areas of Aleppo during the day, conducting more than 70 strikes and dropping at least 100 bombs.

25 September

• Intense Russian and Syrian airstrikes in and around rebel-held areas of Aleppo, Syria, kill at least 85 people, with observers claiming that attacking aircraft are employing white phosphorus munitions, cluster munitions, and incendiary and "bunker buster" bombs. Since 19 September, the strikes have destroyed so many ambulances that humanintarian aid workers and first responders have great difficulty responding to reports of casualties. At the U.N. Security Council, United States Ambassador to the United Nations Samantha Power accuses Russia of "barbarism" and claims the strikes are a war crime, while the Permanent Representative of Russia to the United Nations, Vitaly Churkin, responds that the collapse of the ceasefire is due to transgressions by U.S.-backed rebel forces.

27 September

• The U.S. Federal Aviation Administration demonstrates its Next Generation Data Communications (also called "Nexcom" or "Data Comm") system - a component of its Next Generation Air Transportation System - to the media at Washington Dulles International Airport in Virginia. The system, already installed at air traffic control towers at 45 airports in the United States, is intended to replace the existing archaic U.S. system of communications between airline pilots and control towers - which requires printing out flight plans in towers, discussion by radio between towers and pilots, and pilots writing down flight plans by hand in the cockpit - with all-digital communications, allowing improved speed and efficiency. The FAA plans to install the system at 50 more U.S. airports before the end of 2016, and then to install it at en route air traffic control centers across the United States, with a goal of achieving voiceless, in-flight communications between air traffic controllers and airliner pilots throughout the country by mid-2019. The FAA estimates that the new system will save air carriers $10,000,000,000 over the next 30 years.

The announcement states that in a telephone conversation earlier in the day with Russian Minister of Foreign Affairs Sergey Lavrov, U.S. Secretary of State John F. Kerry "made clear that the United States and its partners hold Russia responsible for the situation, including the use of incendiary and 'bunker buster' bombs in an urban environment, a drastic escalation that puts civilians at great risk" and "informed [Lavrov] that the United States is making preparations to suspend U.S.-Russia bilateral engagement on Syria -- including on the establishment of a Joint Implementation Center to coordinate [air]strikes on terrorist targets -- unless Russia takes immediate steps to end the assault on Aleppo and restore the cessation of hostilities."
• A Dutch team investigating the crash of Malaysian Airlines Flight 17 in Ukraine in July 2014 announces that it has concluded that the airliner was shot down by a surface-to-air missile fired by a Russian-made Buk missile system (NATO reporting name "Gadfly," U.S. Department of Defense designation SA-11) smuggled from Russia into an area of eastern Ukraine held by pro-Russian separatists a few hours before it fired at the airliner and returned to Russian territory the following day. The Dutch team says that it has identified over 100 people linked to the firing of the missile and that it will continue its investigation - extended into at least 2018 - -in order to determine who ordered it fired. The U.S. Department of State notes that the Dutch team?s findings match those of American investigators, while the Russian ministries of defense and foreign affairs dismiss some of the Dutch team?s evidence and declare its investigation biased and Russian separatists in Ukraine claim they have no access to sophisticated surface-to-air missiles and blame the airliner?s destruction on the Ukrainian armed forces.
• "Unauthorized...activity" by an unmanned aerial vehicle near Dubai International Airport in Dubai, United Arab Emirates (UAE), forces the airport to halt all arrivals and departures.

29 September

• United Nations officials condemn the 28 September U.S. counterterrorism airstrike in Afghanistan?s Achin District, saying it killed 15 civilians and wounded 12 others; they demand a complete investigation of the incident. Although the United States and the Afghan government claim that the strike targeted a residential compound used by Islamic State personnel, local Afghan officials claim that it killed and injured only civilians. U.S. military officials respond that they take "all allegations of civilian casualties very seriously" but add that the Islamic State continues "to put innocent lives at risk by deliberately surrounding themselves with civilians and dressing in female attire."
