Air India Flight 855 was a scheduled passenger flight that crashed during the evening of New Year's Day 1978 about off the coast of Bandra, Bombay. All 213 passengers and crew on board were killed. The crash is believed to have been caused by the captain having become spatially disoriented after the failure of one of the flight instruments in the cockpit. It was the deadliest aviation accident in India until the Charkhi Dadri mid-air collision in 1996, and is still the second-deadliest behind the latter accident.
