Investigation Summary

The bombing was orchestrated by the Babbar Khalsa separatist group as retaliation for the Indian Army's 1984 raid on the Golden Temple. The plot involved two bombs: one destroyed Flight 182, while a second exploded prematurely at Tokyo's Narita Airport, killing two baggage handlers. The explosives were hidden in luggage checked in Vancouver by passengers 'M. Singh' and 'L. Singh,' neither of whom boarded the flights. Despite warnings and surveillance of key suspects like Talwinder Singh Parmar, Canadian intelligence (CSIS) and police (RCMP) failed to prevent the attack. A subsequent 2010 public inquiry cited a 'cascading series of errors' by Canadian authorities, including the destruction of wiretap tapes and poor inter-agency cooperation.

Final Conclusions

The disaster was caused by a deliberate act of terrorism. The investigation concluded that a Sanyo tuner packed with dynamite and a timer was placed in a suitcase. The primary failure was in airport security protocols that allowed 'interlining' of baggage without the passenger being on board. Legal proceedings lasted decades, resulting in only one conviction: Inderjit Singh Reyat, who pleaded guilty to manslaughter.
