The deadly Air India crash has renewed a decades-old debate in the aviation industry over installing video cameras to monitor airline pilot actions.

A cockpit recording of dialogue between the two pilots of the Air India flight that crashed last month supports the view that the captain cut the flow of fuel to the plane's engines, said a source briefed on U.

The captain of the crashed Air India jet is likely to have cut off the fuel supply before it went down in Ahmedabad, US officials believe.
