July 8th, 1965. Air Traffic Control in Vancouver was relatively quiet, and everything appeared normal. All of a sudden, they received a transmission “Mayday, mayday, mayday” but from who? Little did they know, one of their passenger planes carrying 52 people on board had crashed in a forest near 100 Mile House in the Cariboo Regional District of British Columbia. An explosion inside the plane caused it to spiral towards the earth. But this explosion wasn’t accidental, it was a bomb. Who planted this bomb and why? Answers that have eluded investigators to this day making this one of Canada’s biggest unsolved cold cases. Did police have the right suspects, or did someone get away with mass murder undetected?
