A veteran commercial airline pilot said he may have found a “total game-changer” in what led to the doomed Air India Boeing 787 to crash after analyzing new video.

A shocking new video shows the moment the single survivor of the Air India plane crash escaped the wreckage. The clip, which emerged today, shows British-Indian man Vishwash Kumar Ramesh walking out of a huge billowing cloud of grey smoke where the crash had happened.

The crash happened just weeks after the company cut a deal with the U.S. government to avoid taking criminal responsibility for a pair of deadly crashes in 2018 and 2019.
