A landing gear support broke as a Delta Air Lines regional jet was landing before it flipped upside down, leaving passengers “hanging like bats” at Toronto Pearson International in February, according to a preliminary report from Canada’s Transportation Safety Board.

The preliminary report into the Delta Air Lines flight that flipped upside down in a crash landing at Toronto's Pearson International Airport last month has been released, and shows the plane had been descending at a high rate of speed.

Investigators say a high-speed descent led to a landing gear collapse that caused a Delta Air Lines plane to flip upside down in Toronto in February.
