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.

Indian authorities have started handing over remains of the victims of one of India’s worst aviation disasters after identifying some through DNA tests.

Air India flight AI171, a Boeing 787-8 carrying 242 people, crashed after taking off from Ahmedabad on its way to London.

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 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.

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.

Air India plane crash investigators have found both of the Boeing 787's "black boxes," hopefully brining an understanding of the cause of the disaster a step closer.
