Stunning new video of a Delta Air Lines flight crashing while trying to land in Toronto, Canada, has emerged, showing the moment the passenger jet careens across the tarmac, catches alight and rolls onto its roof.
Eighty people were on board the flight from Minneapolis when it crashed in icy conditions. In the latest update, authorities said 21 people were initially hospitalised and now all but two have been discharged.
The chief of Toronto Pearson International Airport, Deborah Flint, said on Tuesday, local time, that the two people who remain in hospital were not facing life-threatening injuries.
In a recent update from the Transport Safety Board, a senior investigator said the wreckage had come to a stop slightly off the runway and facing the wrong direction.
In the video filmed adjacent to the runway, the CRJ900 jet can be seen coming in for what the videographer expects to be a normal landing.
The conditions are icy and windy, but that's typical for Toronto at this time of year, even though there had been an abnormally high level of snowfall over the weekend.
As the video tracks the jet, it captures the moment it first touches down on the runway.
Several passengers have spoken to media about their experience of the landing.
In the video, the plane's landing gear is visible as it makes its approach.
Passenger John Nelson was on the flight and said: "We were coming in, and I did notice that the winds were super gusty, the snow had kind of blown over the runways".
"And so coming in, it was routine, but it was noticeable that the runways were kind of in a weird condition, and when we hit, it was just … super hard," he told CNN just hours after the crash.
The fire chief for the local area did say in a press briefing that the runways were "dry" and the airport boss would not be drawn on whether snow played a role, but did say that even for a Canadian winter, the recent weather had been "extreme".
The crash happened on Monday but came after days of record snow.
"On Thursday and Sunday, we got more than 20 inches (50 centimetres) of accumulated snow. That is actually not typical. In fact, it is more snow within that time window than we received in all of last winter," Ms Flint said.
Another passenger, Pete Carlson, also remembered the initial touchdown of the plane on the runway being rough.
"As we made our descent and made touchdown, it was just a very forceful event where all of a sudden everything just kind of went sideways."
As can be seen, upon that touchdown, the plane immediately starts to skid, and within a fraction of a second, flames can be seen.
"We hit the ground and the plane went sideways, and I believe we skidded, on our side, and then flipped over on our back where we ended up," Mr Nelson said.
"There was like a big fireball out this left side of the plane. And when we got finished, I was upside down."
Mr Carlson described the sounds he was hearing at that moment.
"One minute you're landing and kind of waiting to see your friends and your people, and the next minute you're physically upside down and just really turned around," he said.
"But it sounded, I mean, it was just cement and metal."
Mr Nelson said he heard "a loud bang".
"It happened so quickly, right? You hit, there's this giant pop crack, … this super loud bang," he said.
"And then everything just goes literally sideways, and it happened so fast that I just remember kind of pulling myself in and trying not to hit my head against anything."
A slowed-down version of the crash shows the moment it rolled over and lost one of its wings.
It shows the plane is skidding along the tarmac and becoming unbalanced.
Mr Nelson said he was in row 10, sitting just in front of the wing, but at that stage of the crash he had no concept of what was happening to the aircraft itself.
"No, by that point, we were being tossed around. I was just trying to hold on to everything at that point," he said.
When the aircraft came to a stop, the passengers and crew were upside down, but alive.
Mr Nelson said he could smell a chemical, likely the aircraft's fuel.
"I mean, it was mass chaos. I was upside down. The lady next to me was upside down," he said.
"We kind of let ourselves go and fell to hit the ceiling, which is surreal feeling. And then everybody was just like, 'Get out, get out, get out.'
"We could smell jet fuel … and then we just crawled out the back of the airplane. The firefighters … were there right away."
It is not yet known what caused the crash landing but Canadian authorities will handle the investigation.
On Tuesday, senior investigator at the Canadian Transport Safety Board Ken Webster recorded an update on the incident while standing next to the fuselage in freezing weather.
He said the plane collided with the runway and then "parts of the aircraft separated, and a fire ensued," he said.
"As you can see here, the fuselage came to rest slightly off the right side of the runway, upside down, facing the other direction," he said, gesturing at the destroyed aircraft behind him.
The response from the airport's emergency staff has been called "textbook" as the 76 passengers and four crew were swiftly evacuated from the burning wreckage.
Several were flown to hospital.
Mr Carlson, reflecting on the evacuation said: "What I saw was everyone on that plane suddenly became very close in terms of how to help one another, how to console one another. And that was powerful."
When Mr Nelson was on the tarmac, realising he had survived a plane crash, he took video of the scene that has now been seen across the world.
He can be heard saying: "We're in Toronto, we just landed, our plane crashed, it's upside down. Paramedics are on site … most people appear to be OK, there's a lot going on."
He also told CNN that at that stage: "Shortly thereafter I got done filming the video, there was another explosion. But luckily, the firefighters got … there."
Also on Tuesday, airport boss Ms Flint again thanked the first responders and said two runways remain closed as transport authorities begin their investigation.
"I cannot commend enough the crew, the flight attendants, pilots and our emergency responders for their quick and effective response," she said.
"It's really, really incredible. And when you see that aircraft, it just makes you really thankful for all the safety checks that go into running this…one of the world's safest air transportation systems."
