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 proximity warning system aboard the Delta Air Lines flight that crashed at Pearson airport last month sent an alert indicating a high rate of descent less than three seconds before the plane touched down,

A new report into the Delta plane that crashed and flipped at a Toronto airport last month outlines how the crew was battling winds and landed hard without pulling the nose of the plane up to ease the landing.
