The preliminary report from investigators probing the Air India crash that killed 260 people showed that seconds after takeoff, the Boeing 787 plane's engine fuel control switches were switched off briefly,

The Air India airliner carrying 230 passengers and 12 crew members was on its way to the United Kingdom when it crashed into a building shortly after takeoff on June 12, killing all aboard, except for one survivor, and several people on the ground, according to authorities.

As per the report, these switches transitioned from ‘RUN’ to ‘CUTOFF’ position within a second of each other moments after lift-off, leading to the worst aviation disaster involving an Indian airline in four decades.
