Two small planes collided over a bustling Quebec shopping mall on Friday. One person was killed and three people were injured. Here is a look at some other mid-air collisions in Canada:
April 8, 1954: A Trans-Canada Airlines Canadair C-4 North Star is struck by a climbing Royal Canadian Air Force Harvard trainer over Moose Jaw, Sask. The crash sends debris raining down on the community and the much larger passenger plane just misses a school full of kids as it plummets to the ground. Thirty-five people on board the passenger plane are killed along with the Harvard pilot and one person on the ground.
