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.

The Boeing 787-8 Dreamliner carrying 242 people bound for Britain's Gatwick Airport began losing altitude seconds after takeoff. All but one passenger died in the world's worst aviation disaster in a decade, with around 30 ground fatalities.

Investigators in India are studying the black boxes of a Boeing 787 Dreamliner after recovering them from the aircraft wreckage to ascertain the cause of last week's plane crash that left at least 270 people dead.
