I wonder why were they filming? Was there an early warning? Was it a sketchy landing in any case? I mean aircraft are fascinating and people film them all the time but wouldn’t expect a pilot sitting in another one to casually film landings. Maybe just an extremely lucky catch.

Probably just because pilots generally think planes are cool, especially when landing, and there's not much else to do while waiting in line but film them.

...after they've completed all their checklists and are ready for takeoff, of course.

Clear view from the plane waiting to take off https://www.reddit.com/r/CatastrophicFailure/comments/1isabt... Which also brings into mind cockpit distractions but its amazing they caught this on video.

From the same thread, an AMA by a passenger:

Just to emphasize how insanely lucky they were:

> From inside we didn't see any of the fire, thank goodness! We were all upside down to start with, but many of us were able to release themselves pretty quickly. After that the "upright" of us helped the upside-down until we were all righted and ready to evacuate. We were able to quickly get out the one emergency exit that was safe, the other one poured jet fuel in when they opened it.

From the NOTAM, the runway condition codes for 23 were 5/5/5, so not dry, but "good". [1] https://avherald.com/h?article=52439b47&opt=1

5/5/5 would still be good braking action and directional control (it’s out of 6).

I stand corrected.

5 is not "poor", but "good", with a wet runway or one with light snow or slush. [1]

You can see it in CGPGrey's long defunct Hello Internet podcast. He talked about aviation disasters often and name dropped hacker news a few times.

It's mystifying that any airport with commercial service doesn't have cameras with a full view of every runway recording 100% of the time. You can't steal a catalytic converter without being on video. We have webcams placed behind eagles' nests in our national parks. Yet somehow we have no recordings of plane crashes at our airports. Then of course there's the lack of cameras on the planes themselves...

It happens to be that another pilot from a plane waiting to take off form the very same runway was filming the approach [1]. Purely by chance we have HD footage. It does make a huge difference and I agree with the sentiment that this would make flying safer. [1] https://www.instagram.com/reel/DGNgCI0MC68/

That's the first clear footage that I've seen (i.e. from an angle not obscured by smoke). To me it looks like the plane touched down with a slight tilt to the right, then the rear landing gear buckled (possibly -- those might be snow dunes obscuring the actual position of the runway) causing the right wing to hit the ground and break off. Then the plane continued to slide on its side for a second before tipping upside down.

Others are saying the plane hit the ground quite hard, I have no frame of reference to judge that.

Nice video!

No flare, hard landing, landing-gear collapse. Ouch.

Here you go: https://www.reddit.com/r/aviation/comments/1is1qoy/video_of_...

the video was removed

Here's another view. I was at least partially wrong - looks like the pilot just flew it into the ground. Hard enough hit to collapse the gear.

Look up stress to failure tests on commercial airplanes. They know how much peak load is supposed to be for the airframe, then they go well beyond it to see how the plane fails. Generally you want the wings to break not the fuselage. You can in a lot of situations land a plane with 1.5 wings. But once the spine cracks you’re just a ballistic object.

The parts are designed for "ultimate load" which is 150% of the worst case maximum load expected to ever see in service. I used to work at Boeing on the 757 stabilizer trim system. There's the design group and the stress group. I was in the design group, the stress group double checks the design work. One day the stress group called me on the carpet, and asked me why my designs consistently just barely exceeded 150%.…

> If they didn't like the design requirements, change them.

If anyone is wondering, this is always the correct answer when there’s a disagreement between reality and the specification and you’re following the spec.

Holy shit, that was just pure luck that no one end up dead. Based on the video, the plane glide-flipped just enough to slide/roll itself out of the major fire. Things could be a whole lot worse if it played out just slightly differently.
