Investigators have recovered the cockpit voice recorder (CVR) from the Air India flight that crashed shortly after takeoff outside Ahmedabad airport last week. All but one passenger died after the London-bound Boeing 787 aircraft crashed into the campus of a medical college in Ahmedabad city on Thursday afternoon.

Air India had hiked the insurance cover on the ill-fated Boeing 787-8 Dreamliner aircraft from Rs 750 crore to Rs 850 crore following an engine replacement in April this year, Times of India reported citing people familiar with the matter. The total claims from the plane crash are expected to exceed Rs 1,500 crore, the report added.

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.

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.
