Which also brings into mind cockpit distractions but its amazing they caught this on video.

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.
welp guess i'm never flying again
To give an extreme example, imagine someone starts passenger service from Earth to some planet in the Andromeda galaxy. Each flight carries 100 people. Once the warp field is stabilized the rest of the trip is 100% safe. However when the warp field is turned on their is a 99% chance that it will collapse rather than stabilize, which will destroy the ship and kill everyone aboard.
These Andromeda flights are 5 orders of magnitude safer than commercial air travel when measures by passenger fatalities per mile.
Similarly, the risks for specific drivers in specific vehicles making specific trips isn’t the same as the risks for the average driver making an arbitrary trip.
Absolutely incredible the fireball was put out in the flip, these people are so lucky.
But still, that’s astonishing footage in the Reddit post linked above. Incredible that no one died.
It takes a fair amount of heat / pressure to ignite jet fuel, easier if it’s vaporised.
There's a reason water is used for firefighting.
Kerosene (Jet-A) is relatively nonvolatile and tends to burn most violently when dispersed in air. It's not quite as heavy as diesel fuel, in which you can extinguish a lit match, but conditions in this incident probably limited flame development considerably.
If you're going to rip a wing off do it as early in the crash as possible so momentum will carry you past the fuel/fireball.
If fire develops when you've almost or completely stopped you are now involved in the fire and the fatality rate goes up dramatically.
Whether the folks controlling these recordings would publicly release them is debatable (especially as it may be seen as being in bad taste due to the trauma these folks experienced and especially especially if anyone had died or ends up dying from injuries sustained).
No flare, hard landing, landing-gear collapse. Ouch.
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.
Slight tangent, if you are on an airplane that lands smoothly despite bad weather and crosswinds, compliment the pilot as you leave the plane. I once offered a "That was a damned impressive landing in this wind" on my way off an airplane and the pilot simply beamed with pride.
> 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 since Friday, and are experiencing wind gusts up to 65 mph. Has basically been a winter hurricane.
> This is a CRJ landing on Runway 23 at YYZ. It is an 11,000’ runway. Winds at the time where gusting from the NE likely north of 30 knots, so this was a cross wind landing. My bet is that it wasn’t the worst situation that any of the pilots had been in. Delta is a pretty good company. Guessing (as a GA pilot and talking to pilots of bigger birds than this —- I know a few). Likely wind shear or wake turbulence. The wake turbulence part would be a reach considering the cross wind component would have blown it away by the time of this landing.
Max allowable crosswind component for takeoff and landing on a runway when the braking action is “FAIR” => 20 knots
That also seems to overlap with what is being discussed by CRJ pilots in this reddit thread [2] (EDIT: also discussed today here [3])If the METAR is correct, they were landing with a crosswind of 28 knots, gusting to 35, on what doesn't look like a "dry" runway. So they might have been over their operational limits here.

However the runway landing was 33, or 330° magnetic.
So this is 24-30kt crosswind component. The maximum landing crosswind on a dry runway is 32kt. The press conference reported the runway as dry, so if they’re correct then it’s within limits. At the reported -9°c if the runway has been de-iced it could be dry I guess?
The surveillance potato camera makes it look like a hard landing on the right main, which is mounted on the wing root. But it’s very low quality and we’re not going to get the first real answers for a month.
They were landing on runway 23.
> At the reported -9°c if the runway has been de-iced it could be dry I guess?
From the NOTAM, the runway condition codes for 23 were 5/5/5, so not dry, but "good".
You basically had to fly straight over the city, high rise buildings straight ahead, and bank right as hard as the plane would let you at just the right time to hit the runway.

Was such a harrowing experience that, when travelling back home from abroad, I try to fly into Port Hedland and then just take a 10-hour bus ride. (Okay, I admit that I do that mostly so I can get my jet-lag adjusted at the beaches of Shark Bay along the way .. ;)
They are landing on runway 23, with, from the METAR, wind coming from 270 at 28 knots. That's more than enough crosswind to clear any wake turbulence that could have been there. (See [1])

I've been flipped slideways flying short final (cessna) by a heavy jet that departed 90 seconds prior on a parallel runway. Fortunately I was high enough to recover, but it could have gone very differently.
Wind shear seems more likely this close to the ground, but I'm sure we'll get a nice write-up after the investigation.

But the snow rates were slow enough yesterday that I don’t think that was happening.
Here is a link to the .mp3 file (it's on Discord for now - I don't know if this is allowed, let me know if it isn't):

Good point about exporting to Opus! I used .mp3 because the original audio files were also in .mp3. I've re-exported the file in Opus now, let me know what would be the best way to send it to you.
As for file name and credits, I think it's probably best to credit LiveATC (https://www.liveatc.net/), since that's where I got the original audio and I didn't really do much else beyond separating the channels. The specific files I used are the YYZ Ground and YYZ Tower recordings from February 17th that start at 1900z.
See the comment above about hosting the file in a more permanent way.
I'm more surprised the wing rupture didn't cause a fire/explosion because this is where most of the fuel is stored.
Unless you're a checked bag.
* Approach seems mostly unobjectionable (reasonable rate of descent, plausible looking approach speed)
* Runway not especially slick
* May have touched down short and left of centerline
Hope for a preliminary report from Canada Transportation Safety Board in a couple weeks.

He suspects landing speed may have been too low, making it impossible to flare correctly.
(Both channels are former airline pilots.)
edit: apparently Canada banned PFAS in firefighting foam.
Also plenty of delta flights will layover at MSP.

On a side note, it is crazy someone would take a selfie video before exiting a crashed airplane.
It's literally once in a lifetime, and it didn't look like anyone was in serious danger after they realised they'd survived.
There was fuel gushing from the severed wing, hence why the water spray just above one of the exit doors, and you could see fire trying to flare up. It had the potential to turn catastrophic...or more catastrophic...in an instant.
There was a lot of behaviour that isn't super ideal, for instance people milling right near the plane seemingly to take videos/photos not only restricting the emergency crews but in a danger area.
I get people in shock from a near death experience doing irrational things like that, though. More concerning are the number of people rationalizing it with full clarity and consideration. Like on Reddit the number of people talking about how there is no way they were leaving their carry-on because their laptop has important work, or their bottle of aspirin, etc...just disastrous logic that literally gets people killed. Standing right in the area where emergency crews are trying to stop a plane from erupting into a fireball for that once in a lifetime selfie -- absolutely crazy behaviour.
I can't fine tune that number to determine you survived the crash, but then died from smoke or fire, since it did not easily differentiate pre-crash and post-crash fires.
I am not sure I would agree or disagree that it is usual to die from smoke inhalation after surviving a plane crash given the reason that people took too long to evacuate. It just feels like the upper limit of how many people die that way can't be that large since many of those smoke/fire deaths would not be attributable to that cause.

People just having been in a crash, however, are in a different situation. They've just been thrown upside down, having to release their seat buckles and fall down onto the roof, then being ushered out in panic. Them not behaving perfectly rational should be excused.
If you want something to happen in an emergency, you either drill it to be instinct, or it won't happen reliably.

Unverified reports by another pilot are that the plane struck a wing then sort of cart wheeled
I don't think the "wing struck ground" is really an accurate description based on this footage.
'I was just in a plane crash. Oh my God,' says one woman who filmed herself upside down in her airplane seat.
Is a goddam surreal sign of the times. Absolutely surreal./r/aviation thread: https://old.reddit.com/r/aviation/comments/1irsmp8/airplane_...
Have there been any recent with major commercial jets yet ?
Less than a week ago, a 737 hit a truck on the runway in Rio de Janeiro, and last Christmas an ERJ E190 was shot down Azerbaijan, followed a few days later by a 737 in Korea smashing into a concrete wall after the end of the runway.
The DC collision was an accident waiting to happen, but that airport only serves single-aisle jets and runway 33 can only be used by the smallest of those - like the CRJ and Embraer model.
And in this case, it remains to be seen what caused the unexpected roll.
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...
I understand there is a public Voyeur interest in seeing crashes, but how does releasing footage of accidents aid investigation or safety outcomes?
I also read scuba-diving accident reports. They reinforce best practices that I also explain to others in the context of what I've seen in said reports over and over.
Crashes aside, a high-res Tower view would also make a great live webcam for enthusiasts to watch while listening to LiveATC.
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.
Others are saying the plane hit the ground quite hard, I have no frame of reference to judge that.
Looks like the plane landed incredibly hard and the gear buckled. Extreme wind shear?

Quality is not good enough to tell for sure, but to me, looks like wind shear causing a tail strike followed by gear buckling
the Navy pilot jokes showed up fast in that thread
Yes, that's technically video I guess, but it's trash and doesn't look like the camera was set up to capture takeoffs and landings. More like a utility shed and road... at '90s webcam frame rates and quality.
Also, I've flown a lot of Korean Airlines flights where they have front, down and side view cameras that you can watch on the entertainment console. I'm sure it's just a matter of time before more airlines adopt it.
There are videos of thieves stealing them on YouTube, but we don’t have any footage.
Most cabins today have CCTV cameras on board.
It’s an interesting privacy concern really. Pilots don’t like the idea, somewhat understandably, who wants to be watched at work every minute of their day? But then it’s also a safety benefit and maybe that’ll win out eventually (this question does keep getting raised on certain crashes).
Nb: I do know that the actual condition of 'shock' will sometimes induce irrational behaviour.
I'm quite sure I have heard about more plane accidents in the last two years than in the entire fourty years of my life before that. This is absurd.
what's the root cause
You're just hearing about it more because there are more planes than ever before, and more media exposure than ever before.
Its only commercial airline crashes in the USA that are vanishingly rare. Once you expand scope to all types of planses or the world as a whole you get a lot more.
Which leads to my repeated bafflement as to why there are no video cameras constantly pointed at flight ops at the airport.
If every 7-11 can have a security cam recording hi-def 24/7, why can't a couple of these be mounted in the tower pointed at the tarmac?
It came down really, really hard, gear collapsed asymmetrically it seems, causing it to roll to the side and sheer one wing off then start rolling.
And FWIW, the conditions of the runway were, by all reports, excellent. It was considered "dry" conditions.
It seems a lot more likely the security managers aren’t in a hurry to release them to the public.
Best one so far is this one from the next in line plane that would have taken off next: https://old.reddit.com/r/aviation/comments/1isabv4/another_a...
But that doesn't stop breathless click-bait headlines proclaiming that the crash was "caught on video."
Air travel actually has a lower fatality rate per mile than trains do. Rail crossings can be dangerous places.
The accident occurred on the ground, any aircraft is susceptible, “more trains” doesn’t make it less so.
I feel like major airline crashes are usually headlines.
Not really, how many of these accidents from last year do you recognize?
https://en.wikipedia.org/wiki/List_of_accidents_and_incident...
It gets all over the news when a whole lot of people die, for evident reasons.
The problem is everyone seems to have survived
On the other hand, the concentration of people who are interested in planes/flights are definitely higher on HN than something as generic as Google news

In a highly complex system, all the hacking you need is to allow the ordinary chaotic systems to run more wild and stochastic errors will degrade the system with less traceability than "subtle hacking" — it's hiding in plain sight.
When Facebook or Twitter "Move Fast and Break Things" the consequences are a few users can't use a feature for a while until they notice the issue and patch it.
Do the same with the air transport or health care systems and you start filling morgues.
This has to be one of the dumbest takes out there. Try to work out what could have been cut on the US regulation side that would have caused a crash in Canada such a short time later.
Do you think maybe delta just stopped following the law and let some children fly the plane? Or maybe decided to stop doing maintenance?
Seriously, what is the model here that makes any sense at all?
Can you work out the logical connection for someone who wouldn't understand it?
Spend some time talking to a Libertarian zealot. Not saying that you should believe any of their assertions. Let alone adopt their worldview. But you might get a sense of how less-government-is-always-better "logic" works.
