The London-bound Air India flight 171 crashed into a suburban neighbourhood in the western Indian city of Ahmedabad shortly after take-off on 12 June, killing 241 of the 242 people on board and 19 others on the ground.

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.

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.
