Facts About Malaysia Flight 370: Passengers, Crew & Aircraft
Malaysia Airlines Flight 370 was a passenger flight that left Kuala Lumpur International Airport on March 8, 2014, and disappeared 94 minutes later en route to Beijing Capital International Airport. The disappearance launched an international search effort — some say the largest ever — in an ever-growing area over the South China Sea, Gulf of Thailand and Indian Ocean. Nearly three years later, the fate of the aircraft is still unknown, and the search has been called off.

Passengers and crew
Flight 370 left Kuala Lumpur at 12:41 a.m. local time carrying 227 passengers and 12 crewmembers. People from 14 nations were on board; most of the passengers — 153 — were Chinese citizens; all of the crewmembers were Malaysian. Three Americans were on the flight. Other passengers were from Australia (6), Canada (2), France (4), Hong Kong (1), India (5), Indonesia (7), Iran (2), the Netherlands (1), Russia (1), Taiwan (1) and Ukraine (2).
The manifest released by Malaysia Airlines included an Austrian and an Italian. However, the men have since been identified as Iranian nationals who boarded the flight using stolen passports. Investigators at first thought the men may have been terrorists, but now say they were seeking asylum.
The flight's pilot was Capt. Zaharie Ahmad Shah, 53, who was born in northern Malaysian state of Penang and was a grandfather. He had more than 18,000 hours of flight experience. The co-pilot was Fariq Abdul Hamid, 27, who had 2,763 flight hours. The Associated Press reported that he was engaged and was planning his wedding.
Flight 370 took off in a Boeing 777-2H6ER. The code "H6" is Boeing's designation for Malaysia Airlines, and "ER" stands for Extended Range. It was the 404th Boeing 777 produced. The plane first flew on May 14, 2002, according to the Aviation Safety Network. It had flown a total of 53,465 hours on 7,525 flight cycles (a cycle is one takeoff and landing of an aircraft).
This type of aircraft is configured to carry 282 passengers — 35 in Business Class and 247 in Economy Class. It has two Rolls-Royce Trent 892 engines mounted under its 200-foot (61 meters) wings. The plane has a maximum fuel capacity of 47,380 gallons (179,400 liters) and a range of 7,941 miles (12,779 kilometers). Its cruising speed is Mach 0.84 (640 mph or 897 kph).
This particular aircraft last underwent maintenance on Feb. 23, 2014. A Malaysia Airlines spokesperson said no issues were identified during the maintenance. The aircraft had no history of major incidents before its disappearance. However, it was reportedly involved in a minor ground collision in 2012, which resulted in significant damage to a wingtip, according to Flightglobal.
Malaysia Airlines (MAS) began operations in 1972 after splitting off from Malaysia-Singapore Airlines, which was founded in 1947. The airline's home base is Kuala Lumpur International Airport, with hubs in Kota Kinabalu and Kuching. The airline operates flights throughout East and Southeast Asia, with service to Australia, New Zealand, the Middle East, Europe and, until April 2014, Los Angeles via Tokyo. It has 105 planes in its fleet.
The Aviation Safety Network lists three accidents (not including Flight 370) involving MAS aircraft:
Sept. 2, 1992: Both tires collapsed, as well as the left main gear, causing a Fokker 50 to veer off the runway at Sibu Airport in Malaysia. No one was hurt.
Sept. 15, 1995: A Fokker 50 landed 500 meters from the end of a 2,220-meter runway in Kota Kinabalu. The pilot attempted to take off and try again but crashed into some nearby houses. A total of 34 people on board were killed.
March 15, 2000: Baggage handlers unloading 80 canisters from an Airbus A330 were overcome by strong toxic fumes. Fire and rescue personnel discovered that the canisters contained oxalyl chloride, a toxic and corrosive chemical. Several canisters had leaked, causing severe damage to the aircraft's fuselage. The aircraft was considered damaged beyond repair. A Chinese company was fined $65 million for mislabeling the canisters and destroying the aircraft.
Flight 370 Timeline
March 8, 2014 (all times in local time):
12:41 a.m.: Malaysia Airlines Flight MH370 takes off from Kuala Lumpur International Airport on a scheduled flight to Beijing. The plane, with 239 people onboard, is scheduled to land at Beijing Capital International Airport at 6:30 a.m. local time.
1:19 a.m.: Last communication from co-pilot Fariq Hamid to air traffic controllers in Malaysia, as the plane flies toward Vietnam, across the Gulf of Thailand. Hamid reportedly said, "All right, good night."
1:21 a.m.: The Boeing 777-2H6ER's radar transponder is turned off.
2:15 a.m.: The Malaysian military detects an unidentified object on its radar traveling west. This information becomes public roughly a week later, and the radar target is thought to be Flight 370. The plane then disappears from military radar about 200 miles (322 kilometers) off the coast of Malaysian state of Penang.
6:30 a.m.: Malaysia Airlines Flight MH370 is scheduled to arrive in Beijing.
8:11 a.m.: A satellite detects the last signal from the plane's antenna
Within 24 hours, search operations begin over the Gulf of Thailand. An oil slick on the water is seen near where the plane was last detected, but lab tests eventually show that the oil came from a ship, not a plane.
Search efforts are expanded into the South China Sea, after possible debris is spotted near Hong Kong. Ultimately, Vietnamese searchers are unable to locate objects in the water.
It is also revealed that two passengers used stolen passports to board the flight, which raises concerns about terrorism.
An investigation into the stolen documents eventually finds no link between the men and known terrorist groups. Officials conclude that the passengers were likely immigrants seeking asylum as part of a broader attempt to reach Europe.
Malaysian officials tell a local newspaper that military radar evidence suggests the plane turned around mid-flight.
An investigation is opened into the possibility that Flight 370 was hijacked or sabotaged. China releases satellite images of potential debris floating between the South China Sea and the Gulf of Thailand. The search area is expanded, but the Malaysia government later says the Chinese satellite images do not show parts of the missing plane.
Search efforts move toward the Indian Ocean, as officials try to piece together the plane's flight path after air traffic controllers lost radar contact.
Individuals familiar with the investigation tell the New York Times that the plane lost significant altitude after it lost contact with ground controllers. Intelligence officials probe the possibility that one of the pilots or crewmembers played a role in the plane's disappearance.
The Malaysian government reports that the homes of the pilots were searched, following suspicions that someone onboard may have tampered with the plane's communication system. Investigations continue to examine the possible role the pilots played in the plane's disappearance.
Later, Malaysian Prime Minister Najib Razak says there is a possibility that the plane's communications were "deliberately disabled" before it disappeared and the flight was intentionally diverted, though there is no evidence that the flight was hijacked.
The last satellite transmission from Flight 370 is traced to the Indian Ocean, off the coast of Australia.
An international search operation mounts, focusing primarily on the Indian Ocean. New analyses suggest the plane continued to operate for roughly seven hours after it last made contact with ground controllers.
Indonesia and Australia use patrol aircraft to search large sections of the southern Indian Ocean. Malaysian law enforcement officials expand their investigation to include all passengers, crew and ground staff present on March 8.
Malaysian Prime Minister Najib Razak asks Australia to lead the ongoing search operation.
Reports indicate Thai military radar may have detected Flight 370, but the information was not shared with — or requested by — Malaysian officials until now. Search efforts continue over the Indian Ocean.
The U.S. Federal Bureau of Investigation joins the Malaysian government's ongoing investigation by analyzing data taken from the pilot's home flight simulator. Malaysia defense minister confirms that files were deleted from the program on Feb. 3.
An analysis of the plane's fuel reserves narrows the search area to a smaller region within the southern Indian Ocean.
Satellite images obtained by the Australian Maritime Safety Authority show possible plane debris in the Southern Indian Ocean. The photos, captured on March 16, show two objects possibly related to the missing aircraft. But, despite organized search efforts across an area spanning nearly 9,000 square miles (23,000 square kilometers), patrol planes are unable to detect any debris.
Search planes again fail to locate any debris from the missing Malaysia Airlines jetliner. Analyses by British satellite company Inmarsat find that the plane's steady speed and flight path suggest it is unlikely that the plane was disabled by a catastrophic accident.
An Australian patrol plane spots a wooden pallet in the water within the search zone. A Chinese satellite orbiting Earth captured a new photo of objects potentially linked to the missing Malaysia Airlines flight. The images show a large object measuring about 72 feet (22 meters) by 43 feet (13 m) in the southern Indian Ocean.
The Australian Maritime Safety Authority tries to locate the objects seen by the Chinese Earth-observation satellite but is unable to find any debris within the reported search area.
Images from a French satellite showing potential floating objects are sent to the Australian Maritime Safety Authority. The images, produced from satellite-generated radar echoes, or radar signals that provide information about an object's location, show an object or objects floating about 1,430 miles (2,300 km) off the coast of Perth.
Search efforts again fail to produce any debris in the water.
The Australian Maritime Safety Authority begins investigating two objects detected in the water, roughly 1,550 miles (2,500 kilometers) southwest of the Australian city of Perth. The possible debris includes a gray or green circular object and an orange rectangular object.
Malaysian Prime Minister Najib Razak holds a press conference and announces that up-to-date satellite information indicates the Malaysia Airlines jetliner crashed in the southern Indian Ocean. Razak says further analysis conducted by the U.K. Accidents Investigation Branch concludes that Flight 370 flew along the southern corridor, with its last known position in the middle of the Indian Ocean, off the west coast of Perth.
Razak says the families of the 239 passengers onboard have been notified.
Bad weather, including gale-force winds and heavy rain, stall search efforts for possible debris from the missing plane.
A field of debris in the Indian Ocean, consisting of 122 floating objects, is seen in satellite images, according to Malaysia's Acting Transport Minister Hishammuddin Hussein. The images, taken on Sunday (March 23), cover an area 1,600 miles (2,575 kilometers) off the coast of Perth, near where other satellites previously detected objects potentially linked to the missing Malaysian jetliner.
A Thai satellite spots more than 300 floating objects possibly tied to the missing plane. The potential debris, detected by the Thailand Earth Observation Satellite, is located roughly 1,700 miles (2,740 kilometers) southwest of Perth, Australia.
Investigators in five different patrol planes detect "multiple objects of various colors" within a new search area, which is nearly 700 miles north of the previous area of focus. This new region, about 1,150 miles (1,850 kilometers) west of the Australian city of Perth, is of interest after studies suggest the plane may have run out of fuel earlier, and thus crashed sooner, than previously thought.
An Australian search plane spots at least four floating orange objects measuring more than 6 feet (1.83 meters) in the water.
The floating objects seen the day before are located and retrieved by Australian and Chinese ships, but after some analysis, are not believed to be linked to the missing Malaysia Airlines Flight MH370. A robotic submarine is deployed to try to locate the aircraft's flight recorders, including the plane's black box, which has a roughly 30-day battery life.
A Chinese ship detects sounds, described as "pulse signals," in the Indian Ocean. Investigators say the signals are at the same frequency as the plane's black boxes.
An Australian ship, called Ocean Shield, picks up signals consistent with those emitted from airplane black boxes in the northern part of the designated search area. The first signal lasts 2 hours and 20 minutes, and after the ship turns around, a second signal is detected and held for 13 minutes.
An Australian ship detects more signals that could be from the missing plane's black box. The new signals last a total of 12 minutes.
The Australian Ocean Shield ship detects an oil slick on the water, although it is unclear where the oil came from. A sample of the water is collected for examination.
An unmanned submarine, the Bluefin-21, is deployed to scan the ocean floor and search for debris or wreckage from the missing jetliner.
The Bluefin-21 submarine searches 35 square miles (90 square kilometers) of the ocean floor, but does not locate any debris. In yet another setback, officials say the oil slick discovered in the search area did not come from the missing plane.
Malaysian officials and their international partners investigate a claim by Australian company GeoResonance that it has found possible signs of aircraft wreckage in the shape of the missing aircraft in the Bay of Bengal, 3,000 miles from the current search area in the Southern Indian Ocean.
The aerial search has concluded with no signs of debris, and the underwater search enters a new phase with side scan sonar. The ship Ocean Shield is returning to port to replenish supplies and personnel, and will return to the search with Phoenix's Bluefin-21 submersible.
July 29, 2015
The first confirmed debris are found on Reunion Island in the Indian Ocean.
Feb. 27, 2016
Two more Boeing 777 debris are discovered on a beach in Mozambique. An analysis completed on March 24 concluded that "the debris is almost certainly from MH370," said Darren Chester, the Australian minister for infrastructure and transport. He added that drift modeling explains how debris from the plane, which likely crashed in the Indian Ocean, ended up in Mozambique.
July 22, 2016
Australia, China and Malaysia agree that if the aircraft is not located by the time 120,000 square kilometers (46,000 square miles) have been covered, the search will be suspended.
July 30, 2016
A large wing part found on a Tanzanian island "highly likely" came from the missing aircraft, according to Australia's transport minister.
October 7, 2016
A fragment of a wing discovered in Mauritius in May is confirmed as coming from the missing plane.
January 17, 2017
The underwater search for Malaysia Airlines Flight 370 is suspended nearly three years after the plane vanished without a trace over the Indian Ocean, according to a joint statement from Chinese, Australian and Malaysian officials.
