Investigators are still trying to determine what caused a dramatic Delta Airlines regional jet crash in Toronto yesterday.

Stunning new video shows how the plane flipped over and caught on fire at Pearson Airport.

All 80 passengers survived. 21 people were injured, including two who remain hospitalized.

Air traffic controllers warned pilots of winds up to 38 miles per hour just before the plane attempted to land. It is the latest in a string of significant accidents this year, four in less than a month, including that fatal mid-air collision in Washington, D.C., between a Black Hawk helicopter and a jet that killed 67 people.

For more on all of this, I'm joined by David Shepardson of Reuters. David, good to see you. Thanks for

the latest information we've gotten from officials? Do they have any idea about the cause?

So we do know that the investigators from Canada have recovered the flight data recorder,

Those are going to be read and analyzed.

We should get more information about what happened in those final moments.

But it's clear investigators are going to focus on the actions of the pilot.

crosswinds.

And the one question that is certainly in the minds of experts is, was the plane flaring?

That means when you land, there's a little bit of a pitch up, right, to sort of gently

land on the ground.

And from the videos, it appears the plane was not flaring like a normal plane would.

That could have been because of the pilot trying to deal with these winds, or perhaps the wind

wasn't there at the moment of landing that they thought. So that's one key question. What happened

and why did it appear that the plane landed at such a high rate of speed? The video is just so remarkable.

I know people are taking notice of it, how it landed upside down, but also the fact that
