After touchdown, but it rolled sideways not end over end. This kept the fuselage intact and ripped off the wings (where all the fuel is) which is why everyone survived.
Maybe that would be a general great idea.. slide the people capsule away from the bomb in the final moments of a crash landing. But that would make it necessary to have the people capsule bolted on - with explosive destructible bolts and i think air-companies are not mentally ready yet for the crumble zone airplane.
Many airplanes (not sure about the CRJ) also have a center wing tank, which is directly under the fuselage, so would be kinda hard to separate cleanly. Also, explosive bolts might start a fire that wouldn't have started without the bolts...
And they purge the fuel, if its a controlled emergency landing.. but in a uncontrolled emergency.. to let go of the wings seems a good option for events to go.
No, they don't. The CRJ, and in fact most smaller airliners including the A320 and 737 do not have the ability to dump fuel.
In larger aircraft that do have the ability to dump fuel, the reason is to make the airplane lighter so it does not have do an overweight landing and the subsequent high-cost overweight landing inspection. It is not done to reduce the probability of a post-crash fire.
What you describe in the second sentence - rotating around the vertical-axis - is typically termed a spin .
I think parent was saying the roll was along the planes' length rather than tail-over-nose, the latter usually result in the aircraft breaking up as the torque will be really high.
Thanks - those are correct terms for aircraft in flight, that don't apply to out-of-control vehicles on the ground. An airplane that loses traction and rotates about it's vertical axis is spinning, not yawing.
I’m guessing wind, ice, or something else moved the plane off the centerline and into a crab, it hooked a wheel off the pavement, and cartwheeled. 100% conjecture at this point, just seems like a possible chain of events.
Edit: listing to the ATC audio I think they said gusts in the 30s (man do they ever speak fast and mumble! Enunciate damn it! Unique New York), which is markedly slower than what the Apple Weather app reported for Pearson.
Because the press doesn’t publicize NTSB reports months after the crash. It doesn’t have the same sensational draw to earn clicks. Look up the NTSB docket management system where they release all the reports (just be aware that they list photos as “Text/Image” but videos as “Other”).
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 don't suggest it is any sort of conspiracy, it seems more in line with the generally ancient technology in the air traffic control system, and COBOL for the government accounting systems.
Back in my 757 days Boeing ran individual wires for everything. I suggested using a bus to save weight and improve reliability. I just got blank looks in response. Modern cars use a bus now, and probably the airliners do, but I have no direct knowledge of it.
You were Arthur C. Clarke (geo sattelite case) of aircraft engineering ;-)
Buses are wildly used since 90's. Mostly CAN, the same one used in cars and Avionics Full-Duplex Switched Ethernet (AFDX) -

If the aviation industry is one thing, it is stubbornly conservative. Took like until about a year or two ago to finally get unleaded fuel approved for GA piston engines, and most of the piston engine designs in new production are like over half a century old because no one wants to go through the effort to certify any modern engine for aviation...
Yeah, I know, and I know about the leaded gas situation.
The thing about cameras, though, is you can buy an HD dash cam for $100 that records in a loop. Buy it, plug it in, and point it at the runway. It doesn't need anything beyond a wall socket.
If I was an ATC sitting in the tower, I'd probably just install one myself.
