AirAsia Flight 8501 crashed into the
Java Sea with 162 people on board, halfway into a December 28, 2014 flight from
Surabaya, Indonesia, to Singapore. Dozens of bodies have been recovered, and
search teams have detected what is believed to be the plane’s wreckage.
The pilot told air
traffic control he was approaching threatening clouds and asked to climb above
them, from 32,000 feet to 38,000 feet. But with six other planes in the same
airspace, permission was denied. When the tower tried to make contact four
minutes later, there was no response, and the Airbus A320 was gone from the
radar. The investigation will hinge on the discovery of the black boxes and the
wreckage itself.
With high surf
preventing the deployment of ships that drag “ping” locators, no signals have
been detected from the aircraft’s all-important cockpit voice and flight data
recorders. Both will provide essential information, including the plane’s
vertical and horizontal speeds along with engine temperature and final conversations
between the captain and co-pilot. The black boxes’ ping-emitting beacons still
have around 20 days before their batteries go dead.
A massive
international search effort involving planes, ships and helicopters continues despite
heavy rain, high waves and strong currents. So far, only around three dozen
bodies have been recovered, some still strapped into their seats. Sonar has
identified what is believed to be five large parts of the plane on the seabed,
but rough conditions along with mud and silt have kept divers from getting a
clear visual on it.
Indonesia has
launched an investigation into AirAsia’s operating practices after alleging the
low-cost carrier did not have permits to fly from Surabaya to Singapore on
Sundays, the day the plane crashed. All of the carrier’s flights on that route
have since been cancelled. The Transportation Ministry also has suspended
officials who allowed the plane to fly without authorisation, including the Surabaya
airport’s operator and officials in the control tower. AirAsia has declined to
comment until the evaluation is completed.
