9) Air India Flight 182 – 1985
On the 23rd June 1985 a Boeing 747-237B flying the Montreal-London-Delhi route was blown up at an altitude of 31,000 feet. The aeroplane was in Irish waters at the time and landed in the Atlantic Ocean. 329 people were killed. Most of the dead were Indian Canadians making it the biggest mass murder in Canadian history.
The operation was blamed on a Sikh militant group called Babbar Khalsa. It was thought to be a retaliation for an Indian military operation that ousted hundreds of Sikhs from the area around the Golden Temple. Only one person was ever caught and convicted for the terrorist act and he received 15 years in prison for his handiwork. Thanks to bureaucratic bumblings and murdered witnesses the investigation and prosecution took 20 years to complete and cost $130 million.
