The passenger seat crashed in Toronto appeared to have hit the runway violently before exploding in flames and flipping upside down, a new video showed Tuesday.
A thick plume of fireballs and black smoke wrapped around the Delta plane as it slid to stop on the roof, but 80 people on board were not killed.
“21 injured people were first taken to a local hospital. As of Tuesday morning, 19 people had been released,” the airline said in a statement Tuesday.
Paramedics told AFP Monday that three people were seriously injured, including a child, a man in his 60s and a woman in her 40s.
The flight, which has 76 passengers and four crew members, landed in Canada's largest city in the afternoon and flew from Minneapolis, Minnesota.
Airport fire chief Todd Aitken said it was too early to determine the cause of the crash late Monday.
“It's really important that we don't speculate. You can say that the runway was dry and there were no crosswind conditions,” he said at a press conference.
The video, posted to social media and verified by AFP, was taken from the cockpit of another jet liner waiting for the tarmac.
It marked the moment when the Delta plane hit the ground.
“Ah, no,” the pilot can be heard saying in the video that it turned into a let-diction knit.
The aircraft came to what appeared to be a normal landing as it was slammed against the ground, bounced back and slid forward on the roll on the right.
The moment the flames blow away the swirl, you can see black smoke swirling.
The rescue service responded quickly, spraying water on the jet, shaving its underside and turning black.
Deborah Flint, the CEO of the Toronto Airports Authority, said no other planes were involved in the incident.
A massive snowstorm hit East Canada on Sunday. In Toronto on Monday, when the airline added flights to compensate for the storm's weekend cancellations, strong winds and cold bone temperatures could still be felt.
The Canada Road Safety Board deployed a team of investigators at the crash location.
They will also receive support from the US Federal Aviation Administration, according to U.S. Transport Secretary Sean Duffy.
Airport officials were scheduled to provide an update on Tuesday.
