That's incredible. The plane literally turned over and burnt but no casualty. The flight staff must have done as amazing job keeping everyone calm and helped everyone get out of the upside, burning plane.

"A good landing is when there are no casualties; an excellent landing is when the plane can fly again." This was therefore a good landing.

3 were critically injured, so not “no casualties” but pretty darned close all things considered

It's always interesting to follow the discussions on PPRuNe https://www.pprune.org/accidents-close-calls/664303-delta-cr... Unverified reports by another pilot are that the plane struck a wing then sort of cart wheeled

Indeed. Likely a wing tip strike, the right wing was ripped off, then the left wing is of course still flying so its lifting force rolls the plane over until that wing hits the ground. I think it stayed attached, so after that, the plane just slid to a stop. Edit: Saw a video, looks like the pilot flying failed to flare so they just hit the ground really hard but wings level, probably the landing gear collapsed. Not…

Too late to edit further, but I should add that there could be many reasons for the apparent failure to flare. I did not intend to speculate that the pilot is to blame. That is for the crash investigators to figure out.

The consensus on r/aviation seems to be that it was caused by wind shear. > This looks like wind shear to me. It was a stable approach and then it suddenly got slammed into the ground. That doesn't look like pilot-induced change in descent rate, it is too sudden for that. A sudden change in wind direction (shear) when that slow can absolutely cause a sudden loss of lift. > We have had almost 2 feet of snow up here si…

Wake turbulence almost killed someone I knew flying a training jet. He landed after a heavy aircraft and the cross wind was just enough to counter the natural spreading of wake turbulence. There was basically a horizontal tornado over the runway. When he hit it he lost all roll control. He ended up ejecting horizontally across the grass and somehow survived.

Earlier quoted context omitted.

For anyone unaware, Walter worked for Boeing for years and probably knows more about planes than anyone on the forum. It's likely not a morbid curiosity here, especially since noone died AFAIK, but genuine technical curiosity so he can see what happened, and perhaps educate us readers.

I do have a degree in aeronautical engineering, but I'm not a pilot and don't know a whole lot about flight ops and procedures. Interestingly, I lost my fear of flying once I found out how airplanes were built. I used to know everything there was to know about the 757 stab trim system. It's been a few years, though.

I lost my fear of flying after watching videos of stress tests on passenger planes. Could not believe how strong the wings are.

No; this was the second to come out that night.

Look at the movement of the frame - it's hand held.

It's a recording of a screen playing the video, the hand-held aspect is the amateur getting the footage by pulling out their phone camera and recording a screen...

It looks like the video is taken from https://www.youtube.com/watch?v=VaIL2UOX4ss - it says it's "Kennedy Center Cam", it also wobbles, but that's probably wind. But yeah, it's not an airport camera.

65 mph or 65 kph? I was seeing confusion about the units for that number.

I fly a lot and the only time I've ever thought 'this is it' was one time taking off out of Denver International. The airport is out on the plains east of the city and is known for high winds. We were taking off and nose had just started to lift up when a wind gust cause the entire plane to roll to the left. I could see the wing out my window and am still surprised to this day it didn't touch the ground. The pilot corrected, it felt like, by increasing our angle up and we finished taking off sliding a bit sideways.

Looks like a microburst to me, but same family as windshear
