1985: Air India jet crashes killing 329
A passenger jet has disintegrated in mid-air off the coast of Ireland, killing all 329 people on board.
The Air India flight was only 45 minutes from London Heathrow when it suddenly disappeared from radar screens at 0816 BST.
Airline officials said they do not know the cause of the crash, but suspected it was caused by a bomb planted by Sikh extremists.
The Boeing 747 plunged into the sea from 30,000 ft (9,144 m) and rescue officials said they did not expect to find survivors. The pilot had no time to issue a mayday message, according to the coastguard.
Flight AI 182 was flying from Toronto to London with a stopover at Montreal. Most of the passengers were of Indian origin and intending to fly on to Bombay or Delhi.
