The Air India jetliner that crashed on June 12 was doomed almost immediately upon taking off, after both engines lost fuel supply and the pilots ran out of time to regain control and avert catastrophe.

A preliminary 15-page report filed on July 11 provided the first detailed account of the fateful 32 seconds between takeoff in Ahmedabad and the descent into an urban district just beyond the airport perimeter, where the Boeing Co. 787 exploded, killing all but one of the 242 people on board.
