The Canadian Forces Snowbirds fly over the stadium at the start of the 106th Grey Cup in Edmonton on November 25, 2018. A military investigation has found that the ejection seat of one of the military's iconic Snowbirds planes tangled with the pilot's parachute as he tried to escape from the aircraft before it crashed in the U.S. state of Georgia last year.
