US Navy pilot Captain Steve Scheibner revisits the Air India Boeing 787 crash theory, flagging the Ram Air Turbine (RAT) deployment as crucial evidence.

NEW DELHI (Reuters) -The head of Boeing Commercial Airplanes, Stephanie Pope, met the chairman of Air India on Monday in India, two sources said, as the companies seek to find the cause of last week's fatal crash involving a Boeing 787 Dreamliner.

There have been cases of a very small number of survivors in very serious accidents, but it is "very rare" for there to be only one, a professor told Newsweek.

An Air India crash Thursday involved a Boeing 787-8 Dreamliner, which the aircraft manufacturer first delivered 14 years ago.

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.

Indian authorities have ordered what they called “extended surveillance” of all Boeing 787 aircraft in the country’s fleet while they investigate the cause of the Air India crash.

The Air India flight fell from the sky on Thursday and killed at least 270 people in Gujarat state, officials said Saturday.

Thursday’s deadly crash struck at Boeing’s most ambitious and one of its most commercially successful jet programs — a coveted airplane that airlines the world over gladly wait years to receive.

A London-bound passenger plane crashed in the Indian city of Ahmedabad on Thursday and all 242 people on board were believed killed, with the jet smashing into buildings housing doctors and their families.
