Malaysia Airlines Flight 370 (MH370/MAS370) was a scheduled international passenger flight that disappeared on 8 March 2014 while flying from Kuala Lumpur International Airport, Malaysia, to Beijing Capital International Airport in China. The aircraft, a Boeing 777-200ER operated by Malaysia Airlines, last made voice contact with air traffic control at 01:19 MYT, 8 March (17:19 UTC, 7 March) when it was over the South China Sea, less than an hour after takeoff. The aircraft disappeared from air traffic controllers' radar screens at 01:22 MYT. Malaysian military radar continued to track the aircraft as it deviated westwards from its planned flight path and crossed the Malay Peninsula. It left the range of Malaysian military radar at 02:22 while over the Andaman Sea, 200 nautical miles (370 km) north-west of Penang in north-western Malaysia. The aircraft was carrying 12 Malaysian crew members and 227 passengers from 15 nations.

The multinational search effort for the aircraft is the largest and most expensive in aviation history. The search began in the Gulf of Thailand and the South China Sea, where the aircraft's signal was last detected on secondary surveillance radar, and was soon extended to the Strait of Malacca and Andaman Sea. Analysis of satellite communications between the aircraft and Inmarsat's satellite communications network concluded that the flight continued until at least 08:19 and flew south into the southern Indian Ocean, although the precise location cannot be determined. Australia took charge of the search on 17 March when the search moved to the southern Indian Ocean. On 24 March, the Malaysian government noted that the final location determined by the satellite communication is far from any possible landing sites, and concluded that "Flight MH370 ended in the southern Indian Ocean." From October 2014 through January 2017, a comprehensive survey of 120,000 km2 (46,000 sq mi) of sea floor about 1,800 km (1,100 mi) south-west of Perth, Western Australia, yielded no evidence of the aircraft. Several pieces of marine debris found on the coast of Africa and on Indian Ocean islands off the coast of Africa, the first discovered on 29 July 2015 on RĂ©union, have been confirmed as pieces of Flight 370. However, the bulk of the aircraft has still not been located, prompting many theories about its disappearance. Malaysia established the Joint Investigation Team (JIT) to investigate the incident, working with foreign aviation authorities and experts. Malaysia has stated that a final report on Flight 370 will be released by the end of 2017. Neither the crew nor the aircraft's communication systems relayed a distress signal, indications of bad weather, or technical problems before the aircraft vanished. Two passengers travelling on stolen passports were investigated, but eliminated as suspects. Malaysian police have identified the captain as the prime suspect if human intervention was the cause of the disappearance, after clearing all others on the flight of suspicious motives. Power was lost to the aircraft's satellite data unit (SDU) at some point between 01:07 and 02:03; the SDU logged onto Inmarsat's satellite communication network at 02:25—three minutes after the aircraft left the range of radar. Based on analysis of the satellite communications, the aircraft turned south after passing north of Sumatra and the flight continued for five hours with little deviation in its track, ending when its fuel was exhausted.

With the presumed loss of all on board, Flight 370 is the second deadliest incident involving a Boeing 777 and the second deadliest incident in Malaysia Airlines' history, behind Flight 17 in both categories. Malaysia Airlines was struggling financially, a problem that was exacerbated by a decline in ticket sales after the disappearance of Flight 370 and the crash of Flight 17; the airline was re-nationalised by the end of 2014. The Malaysian government received significant criticism, especially from China, for failing to disclose information promptly during the early weeks of the search. Flight 370's disappearance brought to public attention the limits of aircraft tracking and flight recorders, including several issues raised four years earlier—but never mandated—following the loss of Air France Flight 447. In response to Flight 370's disappearance, the International Civil Aviation Organization (ICAO) adopted new standards for aircraft position reporting over open ocean, extended recording time for cockpit voice recorders, and, from 2020, will require new aircraft designs to have a means to recover the flight recorders, or the information they contain, before the recorders sink below water.


Passengers

Of the 227 passengers, 152 were Chinese citizens, including a group of 19 artists with six family members and four staff returning from a calligraphy exhibition of their work in Kuala Lumpur; 38 passengers were Malaysian. The remaining passengers were from 13 different countries. Twenty passengers—12 of whom were from Malaysia and eight from China—were employees of Freescale Semiconductor.

Under a 2007 agreement with Malaysia Airlines, Tzu Chi—an international Buddhist organisation—immediately sent specially trained teams to Beijing and Malaysia to give emotional support to passengers' families. The airline also sent its own team of caregivers and volunteers and agreed to bear the expense of bringing family members of the passengers to Kuala Lumpur and providing them with accommodation, medical care, and counselling. Altogether, 115 family members of the Chinese passengers flew to Kuala Lumpur. Some other family members chose to remain in China, fearing they would feel too isolated in Malaysia.


Response by air traffic control

At 01:38 MYT, Ho Chi Minh Area Control Centre (ACC) contacted Kuala Lumpur Area Control Centre to query the whereabouts of Flight 370 and informed them that they had not established verbal contact with Flight 370, which was last detected by radar at waypoint BITOD. The two centres exchanged four more calls over the next 20 minutes with no new information.

At 02:03, Kuala Lumpur ACC relayed to Ho Chi Minh ACC information received from Malaysia Airlines' operations centre that Flight 370 was in Cambodian airspace. Ho Chi Minh ACC contacted Kuala Lumpur ACC twice in the following eight minutes asking for confirmation that Flight 370 was in Cambodian airspace. At 02:15, the watch supervisor at Kuala Lumpur ACC queried Malaysia Airlines' operations centre, which said that it could exchange signals with Flight 370 and that Flight 370 was in Cambodian airspace. Kuala Lumpur ACC contacted Ho Chi Minh ACC to ask whether the planned flight path for Flight 370 passed through Cambodian airspace. Ho Chi Minh ACC responded that Flight 370 was not supposed to enter Cambodian airspace and that they had already contacted Phnom Penh ACC (which controls Cambodian airspace), which had no contact with Flight 370. Kuala Lumpur ACC contacted Malaysia Airlines' operations centre at 02:34, inquiring about the communication status with Flight 370, and were informed that Flight 370 was in a normal condition based on a signal download and that it was located at 14°54′00″N 109°15′00″E. Later, another Malaysia Airlines aircraft (Flight 386 bound for Shanghai) attempted, at the request of Ho Chi Minh ACC, to contact Flight 370 on the Lumpur Radar frequency—the frequency on which Flight 370 last made contact with Malaysian air traffic control—and on emergency frequencies. The attempt was unsuccessful.

At 03:30, Malaysia Airlines' operations centre informed Kuala Lumpur ACC that the locations it had provided earlier were "based on flight projection and not reliable for aircraft positioning." Over the next hour, Kuala Lumpur ACC contacted Ho Chi Minh ACC asking whether they had contacted Chinese air traffic control. At 05:09, Singapore ACC was queried for information about Flight 370. At 05:20, an undisclosed official—identified in the preliminary report released by Malaysia as "Capt [name redacted]"—contacted Kuala Lumpur ACC requesting information about Flight 370; he opined that, based on known information, "MH370 never left Malaysian airspace."

The watch supervisor at Kuala Lumpur ACC activated the Kuala Lumpur Aeronautical Rescue Coordination Centre (ARCC) at 05:30, over four hours after communication was lost with Flight 370. The ARCC is a command post at an Area Control Centre that coordinates search-and-rescue activities when an aircraft is lost.
