The
disappearance of Malaysian Airline System Bhd. (MAS)’s Flight 370 has
galvanized a multinational search, spawned theories ranging from an accident to
air piracy and repeatedly dashed hopes that a resolution was at hand.
Below
is a timeline of the events that began with the jet’s departure from Kuala
Lumpur en route to Beijing:
March
8:
12:41
a.m.: Flight 370 takes off from Kuala Lumpur to Beijing with 239 passengers and
crew members on board.
1:07
a.m.: Last transmission from the Boeing Co. 777-200ER via an onboard
text-and-data messaging system known by the acronym Acars.
1:19
a.m.: Last communication from the cockpit. Initial investigation says copilot
said, “alright, good night” as the last words. Plane leaves Malaysian airspace,
heading across the Gulf of Thailand toward Vietnam.
1:21
a.m.: Radar transponder is switched off.
1:37
a.m.: Next Acars transmission is due, and never comes.
2:15
a.m.: Malaysian military radar spots an aircraft on the west side of Peninsular
Malaysia that isn’t using
its transponder. This development won’t be publicly
known until about a week later. The radar target is Flight 370, heading away
from its planned route.
6:30
a.m.: Flight 370 is scheduled to arrive in Beijing.
7:39
a.m.: China’s Xinhua news agency sends a flash bulletin saying contact had been
lost with Flight 370. Chinese passengers make up about two-thirds of the people
on board the plane.
8:11
a.m.: Last satellite signal sent from the plane, known as a “handshake,” is
detected. This development won’t be known for about a week.
8:19
a.m.: Evidence of a “partial handshake” between the aircraft and the ground
station eight minutes after the last complete communication. This information
was released March 25.
9:15
a.m.: No response from the aircraft when the ground station sent the next
message, indicating the plane was no longer logged on to the network.
Initial
search efforts focus on the Gulf of Thailand, where twin oil slicks stir
concern that they signal a crash on the plane’s known route. The discovery that
two passengers were traveling on stolen passports triggers speculation that
terrorism may have been involved.
March
9: Vietnamese searchers find objects in the Gulf of Thailand only to
conclude later that they’re unrelated to Flight 370. Representatives for the
U.S. National Transportation Safety Board, Federal Aviation Administration and
Boeing travel to Malaysia to assist with the investigation. Speculation arises
that the plane deviated from its route.
March 10: Malaysia expands the search area farther into the South China Sea after a plane alerted Hong Kong air traffic controllers about possible debris. Vietnam searchers look for a suspected window piece that was spotted from the air. The leads prove fruitless. Searchers are unable to locate a yellow inflatable object that a Vietnamese helicopter spotted earlier.

March
11: The search expands east again as suspected debris
is found off the coast of Vietnam. One theory evaporates as authorities in
Malaysia and Interpol say the passengers with stolen passports probably aren’t
associated with terrorism.
March
12: Malaysia says a criminal probe is looking into
hijacking and sabotage among other theories. Vietnam says Malaysia hasn’t been
cooperative in search and that the flight may have turned west after last signal.
News reports surface that the co-pilot had guests in the cockpit in a previous
flight.
March
13: Speculation of the crash’s location moves toward
the Indian Ocean as evidence mounts that the flight continued away from its
route after controllers lost radar contact. The shift in focus follows a brief
flurry of optimism for a breakthrough. Chinese satellite images show floating
objects between the South China Sea and the Gulf of Thailand, and the Malaysian
government says later that they are unrelated to Flight 370.
March
14: The Andaman Sea becomes the latest empty lead in
the search. Malaysia looks at the possibility of pilot and crew involvement,
while Prime Minister Najib Razak postpones a trip to Qatar and the United Arab
Emirates to oversee the hunt.
March
15: Satellite transmissions trace the missing airliner
to the Indian Ocean off of Australia. The pilots’ homes are searched, and Najib
says new information shows the flight was intentionally diverted.
March
16: Searchers shift their sights to the Indian Ocean
on the basis of the satellite-signals evidence, which shows that the plane
operated for about seven hours after its last contact with air traffic control.
March
17: Australia leads the search in the Indian Ocean
while the law enforcement probe spreads across multiple fronts. Authorities
discuss pilot suicide as one possibility, police investigate a flight engineer
who was a passenger.
March
18: The disappearance becomes the longest in modern
aviation history. The U.S. joins Australia in the Indian Ocean search, scanning
the waters across an area 1 1/2 times as big as California.
March
19: The U.S. Federal Bureau of Investigation joins
Malaysia’s inquiry, which now includes a probe of data removed from the pilot’s
home flight simulator on Feb. 3. An analysis of the 777’s probable fuel
reserves helps narrow the Indian Ocean search area to a patrol zone about the
size of Italy, half as big as a day earlier.
March
20: Satellite images of objects off Australia’s west
coast spur an air-and-sea search across a remote stretch of the Indian Ocean.
The photos were taken on March 16, and patrol craft aren’t able to locate any
wreckage.
March
21: A second day of air searches turns up nothing. An
analysis of so-called pings from the aircraft by satellite provider Inmarsat
Plc (ISAT) concludes that the plane maintained a steady course and speed after
radar contact was lost. The assessment is consistent with details suggesting
that the plane was commanded, at least initially, from the cockpit and not
disabled by an accident.
March
22: As the mystery reaches the two-week mark and a day
of air and sea patrols produces nothing more promising than a sighting of a
wooden pallet, China announces that scrutiny of satellite scans has revealed a new
image of a large structure in the search zone. The photo, captured on March 18,
appears to show an object measuring 22 meters by 13 meters floating 120
kilometers to the southwest of those in the March 16 images.
March
23: Malaysian authorities disclose that a French
satellite has found radar traces of possible debris, without saying when and
where the images were captured. Search efforts off Australia fail to produce a
breakthrough as more aircraft join the hunt and ships with specialist equipment
begin to arrive.
March
24: Najib, the prime minister, says Malaysia has
concluded the flight ended in the Indian Ocean “far from any possible landing
sites,” ruling out theories of a detour over Asia or an island landing.
March
25: Families and friends of Chinese passengers
protested in front of the Malaysian embassy in Beijing. Malaysian Air and
Boeing’s records of MH370’s maintenance and crew are sought by a law firm
representing the uncle of one of the passengers as Chicago-based Ribbeck Law
Chartered petitioned for information in Illinois state court.
March
26: Satellite images from Airbus Group NV taken on
March 23 showed 122 potential objects in the southern Indian Ocean in a
400-square kilometer area, about 2,557 kilometers from Perth. Some were a meter
in length, and others were as long as 23 meters, and some appeared to be
bright.
March
27: Aircraft searching for the missing Malaysian jet
suspended their operations because of bad weather. Thai satellite images taken
on March 24 showed more than 300 objects in the southern Indian Ocean, while a
Japanese satellite detected about a dozen pieces of possible debris in a March
26 image.
March
28: The three-week hunt for Flight 370 focused on a
new area in the Indian Ocean after radar data indicated the plane probably flew
a shorter distance than earlier estimated. The new zone is about 1,100
kilometers to the northeast of the previous search location.
