GOD Rest their souls

Air India Flight 182 was an Air India flight operating on the Montréal-London-Delhi route. On 23 June 1985, the airplane operating on the route — a Boeing 747-237B (c/n 21473/330, reg VT-EFO) named after Emperor Kanishka — was blown up by a bomb while in Irish airspace, at an altitude of 31,000 feet (9,400 m), and crashed into the Atlantic Ocean. 329 people perished, including 280 Canadian citizens, mostly of Indian birth or descent, and 22 Indians.[1] The incident was the largest mass murder in modern Canadian history. The explosion and downing of the carrier occurred within an hour of the related Narita Airport Bombing.

Investigation and prosecution took almost 20 years and was the most expensive trial in Canadian history, costing nearly CAD $130 million. Only one person was convicted of involvement in the bombing, after pleading guilty in 2003 to manslaughter. The Governor General-in-Council in 2006 appointed former Supreme Court justice John Major to conduct a commission of inquiry and his report was completed and released on 17 June 2010. It was found that a "cascading series of errors" by the Government of Canada, the Royal Canadian Mounted Police, and the Canadian Security Intelligence Service had allowed the terrorist attack to take place.
