A preliminary finding into last month’s Air India plane crash has suggested the aircraft’s fuel control switches were turned off, causing a loss of engine thrust shortly after takeoff.

The London-bound plane had barely left the runway at Ahmedabad airport before it careened back to earth. Everyone on board was killed, except for one passenger.

Authorities released a preliminary report on the Air India crash, following an investigation. The London-bound flight from Ahmedabad crashed minutes into the June 12 flight. Only one passenger of the 242 passengers and flight crew survived.
