This may be hard to believe, but Canada was once home to a flying saucer!
In the 1950s, Canadian scientists in Malton, Ont, began building a top-secret, disc-shaped aircraft for the United States military. It was hoped that this aircraft, known as the Avrocar, would be able to climb vertically and travel at supersonic speed. The military believed such an aircraft would be useful in combat.
Unfortunately, the Avrocar didn’t deliver. During test flights, it couldn’t rise any higher than one metre in the air. Worse, it became very unstable once it left the ground.
Funding for the Avrocar ran out before engineers could fix its flaws. By the early 1960s, the whole project had been abandoned.
