A cockpit recording of dialogue between pilots supports the view the captain cut the flow of fuel to the plane's engines, said a source briefed on U.S. officials' early assessment of evidence.

Fuel control switches for the engines of an Air India flight that crashed last month were moved from the “run” to the “cutoff” position moments before impact, starving both engines of fuel, a preliminary investigation report said early Saturday.

A cut in the fuel supply to the engines caused last month’s Air India crash that killed 260 people, a preliminary report has found. The London-bound plane had barely left the runway at Ahmedabad airport when it hurtled back to earth.
