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.

In a formal statement issued on July 17, AAIB emphasised that the preliminary report only outlines "what" happened, not why, and urged the media and public to avoid speculative or selective interpretations.

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