Air India is facing fresh turbulence following last week’s fatal crash as additional safety inspections on its Dreamliner fleet have led to flight delays, cancellations and growing passenger anxiety.

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.

India’s government is urgently inspecting all Boeing 787s after a devastating Air India crash that claimed at least 270 lives this week, the aviation minister said on Saturday, adding that the authorities were investigating all possible causes.
