Is it possible to collapse the landing gear in that kind of situation and hope it slows down the plane enough to stop in time or would that make it slide even further along the runway?
Threads like this make me really appreciative of CP as a place of discussion, where we have some really knowledge posters with some educated insight on the topic. Thanks Acey, btimbit and others for the perspective. Very hard to watch, can’t imagine what a terrifying experience that would be, and so tragic for the people working there and the family members of the deceased.

That is in a few emergency procedures in some aircraft, but you lose directional control and, I've seen this, they slide a lot further than you would think. I don't know if it's possible or advised in a commercial jet.

Not possible and yeah it'd be a real gamble as you'd lose the ability to steer. Also the fuel is all in the wings, about 7,500 lbs on each side. It's in your best interest to keep those from sliding directly against the pavement at 100 mph

This is probably the most accurate analogy I've seen so far. These are relatively small jets that are very low to the ground. It's basically an extended private jet repurposed as an airliner. "Tank" is the only reasonable way to describe these fire trucks... they are solid as hell.
It's an airplane designed to be as light as possible vs a fire truck designed to be as sturdy as possible, it's no surprise who won the collision.
And its dark and its raining the tarmac is likely very slippery...its just a parade of crappy circumstances.

I honestly feel bad most for the air traffic controller. We don't know his back story but he seems like a guy who right away struggled with what occurred.

Not an expert, but I've seen a fair number of videos of planes crashing on runways. I can't imagine that doing anything that destabilizes the plane would be a good idea. At those speeds, with a fragile plane filled with fuel, anything that could result in a wing, for example, hitting the tarmac seems like an awful idea.

Never flown it, I think the CRJ has an override that would allow it in theory, but to my knowledge no pilot would be trained for that. I'd say you're still better off with hard braking than an uncontrolled slide. Likely dip a wing and start rolling at 100kts

I was thinking that, too. The passenger in the truck would have the best visibility. Would it be their responsibility to do the visual check? Swiss cheese effect?
I drove those crash trucks at YYC for years with CFD before it went private. Most of the trucks it's just the driver however the lead truck usually has the Captain and a driver, I'm assuming that's the case here. But neither obviously looked, you have to be so sure, especially at night. That truck probably weighed about 70,000 pounds

Keep in mind that at 167 km an hour that even if a passenger in the truck saw it, it was likely far too late to react
I can imagine how even in ideal conditions it might be much harder to see a plane that has already touched down than one coming in on approach. I wonder if a better procedure would be a 10 or 15 second stop before crossing an active runway, which would give enough time for a plane in the 'blindspot' to clear, or for a plane on approach to be unmissable...

That video definitely explains it. God I feel for the guy who said he messed up. I could do that multiple times a day. This will be a safety meeting video very soon for us.

I think they had an incorrect graphic showing the plane turning on the tarmac but still.
"The system set him up for failure."
EDIT: As there is more information coming out, I'm just surprised that there wasn't more fatalities. It could have been so much worse. The fact that there was a collision between a plane and that vehicle but didn't hit the wings, the fuel and all without any kind of fire.

That would have also made the impact more direct. The plane was above the truck a bit at least, which may have helped avoid even more injuries.
Captain Steeeeeve likes to make proclamations without facts, and ends up wrong. I'm a layman and even I can see he's unreliable.
Exactly my complaints with him. He's always in a rush to be the first to have a video on a topic, facts be dammed. The the good ones just say "This is horrible, this is what happened, my heart goes out to those involved, I won't speculate, I'll have an opinion when the reports start coming out"
