Delta airlines plane crashes at Toronto airport

Can only guess the landing gears took A LOT of the initial impact. Crazyness.

Took all of it pretty much - completely collapsed, pushed through the wing and took the wing itself with it. The remaining airspeed against the slightly elevated left hand wing and drag on the right side against the ground was apparently enough to make it roll over.

Always wear your seatbelts kids.

Wonder what speed that is when coming down, be interesting to know, I think I read those landing gears are built to take so many x times the impact they usually take for safety margins.

Doesn’t look there was any sort of a flare to arrest the decent and the right gear took the full force or the impact. At least we’ll have the FDR to know the exact figures.
 
Plane literally upside down on fire and it looks like some people still stopped to grab their bags...
 
Absolutely mental that no one died.
it's certainly a testament to the engineering and safety measures involved in the design of the aircraft, seats and restraints.
The freaky thing is this isn't the worst roll during landing/break up during landing I've seen where some/most of the people survived, for all that can go wrong in an aircraft, passenger aircraft are exceptionally well designed to try and keep people alive if possible, and every single accident tends to lead to improvements in the design and operation of them.

It's also a very good reminder of why you should always listen to the aircrew, and ideally only ever take your seatbelt off if you're actually standing up.

A comment on the Pprune thread to which I linked earlier suggest that quite possibly they were bags under the seat that fell down.
 
roll ? wind sheer like for some of the shots linked before from the guy who films big jet landing attempts at LHR, with plane at 45degrees to runway

Interesting bbc podcast about bird strike/culling measures on the hudson & others today https://www.bbc.co.uk/sounds/play/m00282hs

Thought I'd give that a listen as it's one of the things I do for a living.
Quite insightful for those who don't know what happens behind the scenes.
 
(I liked the comment on damage that a frozen chicken would do to a car windscreen versus a jet engine .. in retrospect maybe comparison with a planes windscreen was more relevant)

video - you can't really appraise if there is an oblique angle of approach of the plane to runway for wind, to know if he has to make a steering adjustment as it touches down
Do aerofoils/tail/engines have a significant input at that point or is it down to landing wheel friction?
... hopefully their optimism of no death despite critical injuries is founded.

Flying controls are effective above 80 knots or so - landing speed will roughly 120 knots (give or take a fair bit) so on touchdown you’re still controlling as per flight. Engines will be virtually at idle ready to go into reverse, but can be throttled back up at any point for a go-around, even after touchdown.
 
so they rotate the plane when there is a cross-wind and they land at an angle - by rudder.

Yes - it’s rotated about the vertical axis (yawing) so the direction travel stays on the runway heading even though the nose is pointed off left or right into the wind. About the moment of touchdown this is cancelled out to hopefully make it go straight down the tarmac:


Overcorrect on landing though and it can give the tyres something to complain about:

 
It goes to show the reason why seatbelts are worn, tray tables up with bags away etc. If cargo (and people) were flying around the cabin then the outcome would have been very different.
 
(e: old person was killed on the turbulence in mid-air incident last year ... so probably should always wear belt)

yes those are the type of landings ... even if airport radar cant track the motions I guess black box does.

It also means if you do fall asleep mid flight, then you won't get woken up by someone telling you to put your seatbelt on when you get turbulence mid flight (aside from the safety reason of course).
