A couple of threads going on reddit and some interesting video.

https://www.reddit.com/r/aviation/comments/1xlbwoe...

Descent rate of 32,000ft per minute!

Similar to the Philadelphia Air Ambulance Lear 55 in Jan 2025 and 2012 Nuevo León Learjet 25 crashes?

The reddit link can't be viewed unless you verify your age.

Apparently this was the plane path on flight rader.

after looking at the location on google maps it doesn't look like it hit any buildings. just grass/pavement/road,

32,767fpm is maximum value value for ROC/D as its an 16bit signed integer.

The last altitude vs time stamps on ADSB showed it at nearly 60,000 fpm.

I've just heard the audio between the cockpit and atc. Absolutely harrowing. This one hits a bit close to home. Heart bleeds for all of those involved in this.

Just a friendly note that you really don't need to listen to the ATC recording that's kicking about. The impact was instant, the descent wasn't.

That was a very very fast near verical impact, I'd suspect a lot of the wreckage will have gone deep. Investigation will take a lot of effort, assuming they excavate it, which isn't always the case.

I just read the previous comment about cockpit audio and thought, 'no fking chance'.

Yes there’s EXTENSIVE posts on Reddit saying not to listen to this.

I’ve seen a few folk on there saying impact could have been at 5-600mph. Awful.

Impact was captured on a dashcam, just stumbled across it & the atc audio on YouTube, brutal stuff I d rather not have seen/heard.

Kinda hoping the dashcam is ai, but it looks real enough, plane came in fast if it was genuine, looked like a missile strike

Listening to the audio it appears they were experiencing icing,. precipitation and turbulence at FL350 +/- 600ft. Cells were topping at 40,000 ft in the area.

The crater at the scene seems to match the video.

From the audio it's alarming how quickly it went to st. It goes from sounding mildly uncomfortable about icing and turbulence, requesting permission to climb and then into a 10,000ft per minute dive and then accelerating far beyond that.

I'm assuming that descent rate in excess of 30,000ft per minute, perhaps even close to double that as suggested in another post, couldn't be achieved if the plane was simply falling to Earth, even in a totally nose-down attitude. Were they applying thrust hoping to power out of the stall? It will be interesting to see what went wrong here.

I saw a post saying 'at least they wouldn't have felt anything'. Not on impact, sure, but the 30 seconds or so of uncontrolled terror, screaming at the ATC that they're going to die isn't exactly a peaceful way to go out.

It's a pretty horrific scenario.
Seems like there was a lot of rapidly developing storm cells in the area. They tried to avoid a cumulus nimbus (those tall white clouds you see rising up before a thunderstorm. They're full of rising ice particles, and up/down drafts) Plane tried to get up above it but it was towering over 40,000ft. It's a bit like realising you're heading for a mountain.
The control surfaces iced up and it was game over. Seems like the horizontal stabiliser ripped off in the free fall too.
Terrible.

I was served this audio recording by FB reels as I was eating my breakfast this morning.
That poor, poor pilot.
The terror in her voice is something I don't wish to ever hear again, I can only imagine what was happening in the back.

RIP to all onboard and no, if you haven't already heard the audio, you really don't need to.

I find these threads fascinating as those who know this world far more than me put an insight, I just wish they were in more plain English sometimes so I could understand what happened.

I've seen the dashcam footage and do think its real and not AI though. Reluctant to hear the radio recording now after some of these posts.

Jesus.

Of course the footage is real. How is it even a debate.

Yeah, it is, just seems almost unreal based on the speed its going, seen a lot of plane crash videos but that is something quite different to most.

Must have been absolutely terrifying beyond comprehension.

Absolutely awful. That looked just like a missle hitting the ground.
