A Delta Air Lines flight narrowly avoided a collision with a U.S. military jet shortly after takeoff from Washington National Airport on Friday.

A preliminary report into why a Delta Air Lines jet burst into flames and flipped upside down as it tried to land in Toronto has been released.

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.

Delta Flight 4819 was descending at a rapid rate before crash-landing at Toronto’s Pearson International Airport on Feb. 17, which ultimately resulted in the aircraft flipping over, according to a pre

there were no obvious preexisting problems with the aircraft. In an interview with "CBS Mornings" in the days following the crash, Delta Air Lines CEO Ed Bastian praised the crew of the flight, saying that "all these pilots train for these conditions."

A TSB report reveals Delta Flight 4819 was too fast before crashing in Toronto, leaving 21 people hospitalized.

A preliminary investigation into the crash-landing of a Delta Air Lines flight in Toronto last month revealed the aircraft's alert system warned of a dangerously fast descent less than three seconds before it flipped upside down, caught fire, and skidded to a stop on the runway.
