The fire truck was flipped and moved to the side of the runway, this was not 24mph. 24mph is the final groundspeed recorded after the aircraft skidded off of the runway.

Per the ADSBx track the plane was at 101kts (115 mph / 185kph) just before crossing taxiway D, which would be where it hit the firetruck. It still had enough energy afterwards to reach taxiway E, 600ft away.


Okay that makes far more sense the article didn’t really make that clear to me.

The results seem on the high end but they check out at first glance.

A plane is basically a flimsy tube. A firetruck is a solid brick comparatively. The plane out weighs the fire truck by a lot and out speeds it by a lot. So yeah, destroying the whole front of the plane to punt the truck it sounds about right for a 25 on 5 or 35 on 10/15 type rear ending to me. Flipping doesn't really sound that unreasonable considering that the plane made contact with the top of the truck (just by virtue of comparative height) and contact may not have been straight on. Even if it left the pavement on it's wheels airport firefighters aren't exactly who I'd bet on (they're middle of the pack) to keep the truck on it's wheels if they got surprise kicked off the road especially if there's an embankment involved.


A CRJ 9000 is 70000 lbs empty, 84500 lbs MTOW.

An Oshkosh 1500 4x4 is 62000 lbs GVWR (wiki says kerb weight but it’s incorrect).

The plane was landing and the truck was heading to an intervention, so they were likely close to empty and to GVWR respectively.

And again, 25mph is the final ground speed, after the plane punted the truck and kept on going for 600ft.


*900 not 9000

>25mph is the final ground speed

Wouldn't final ground speed be zero?


Final ground speed reported.

Pause the video at 13 sec. That firetruck is awfully intact for something that allegedly got hit at high speed. Basically just a bunch of top side sheetmetal damage (concentrated to the rear, obviously). In any case it didn't even get sent hard enough to screw up the cab exterior. And on the flip side, if you keep cranking the speed up you start getting to where the plane starts looking too suspiciously intact. There's just not much room to work backwards from the apparent results and get a high difference in speed or get very high initial speeds (100 onto 75 or whatever). If the plane was going fast the truck had to be going fast too or there'd be more carnage. But if they were both going fast you'd expect more damage from the after the fact barrel roll and the plane and truck to be a little farther apart in distance.

Fire truck is filled to brim with gear and doesn't care all that much about weight, plane is the opposite of that, lightness is money, so it makes sense fire truck looks better after crash than plane

Where’s the video you’re referring to?

I can’t tell what’s the truck and what’s the remains of the plane in this pic.

There’s no way this scene happens from a plane colliding with a truck at 24mph.


I'm talking about the headline video from TFA.

The back of a firetruck is not a working implement like a dump truck is nor is it sufficiently strong for mounting a crane or man bucket like utility bodies often are It's a bunch of sheetmetal boxes to hold stuff and cover stuff and there's a water tank back there somewhere. In the middle down low some pumps are buried. Basically don't think of it as being any more structural than a box truck body because it's not. All that stuff got shredded, obviously, since they're only really meant to bear their own weight and were subject to all the truck tossing forces here. Beyond that the truck is in pretty good shape. It's not uncommon for a good "off the highway and into the ditch" crash to rip tandems off, twist frames, etc. None of that has happened here. The plane is pretty rough, but that's expected. They are 100% tin cans. Ground equipment moving at idle speeds will absolutely shred them before the operator even feels resistance. A goose hit square on the leading edge of a small jet's wing will put a massive dent in (and apply red paint, lol).

24 sounds about right for a closing speed for plane onto truck. Whatever the baseline speed of the truck was cannot have been that high or the truck would be absolutely shredded from the barrel roll and as it stand the cab is barely pushed in.


It's interesting to me the lengths people will go with vibes and back-of-the-napkin maths over things that are easily verifiable.

Even without looking up the very public ADS-B data, you are ignoring the fact that ARFF trucks are very much not the same as the average firefighting truck as well as the fact that the CRJ-900 was in the middle of its landing roll (which alone would have been clue enough that it was obviously moving much faster than 24mph).


The article dropped the speed claim.

The last recorded ground speed data of 24mph also shows a wildly different heading (going from 30deg ish to 170ish). So it probably happened after the collision and was part of its deceleration. As far as I know, the truck would have been crossing the runway so the effective speed perpendicular to the plane would be zero except for directional shear I guess.


> A firetruck is a solid brick comparatively.

I think you'd be surprised. The cab is quite solid because it has to conform to certain vehicle design and safety criteria (at least here in Europe).

The rest of it is made of fairly squashy aluminium box section with panels TIG welded on. There's not a lot left if one of them gets rolled, for example.


Both jj and pijul save (~commit) conflicts to be resolved later, rather than require immediate resolution.

And jj was built around rebase being a routine operation, often transparent (cherrypicking being a form of rebasing).


And being in your car doing nothing waiting for the charge for 25mn is frustrating. Even more so when it’s the height of summer (and that was in a car where the AC didn’t block charging).

If you can time it with some errands it’s less of a hassle, but that was one of the main non-car annoyances with my EV rental (the other was the flakiness / unreliability of getting a charging session to start).


I only use public fast charging when on a long road trip. So the 30 min charge always coïncides with me emptying my bladder, so it's never been a hassle.

As I wrote, this was a rental, there was no charger where I was and no mains adapter provided with the car, so my options were fast charger or pushing the thing.

And even during long legs I don’t need to piss for 30mn every two hours.


Python 1.4 would be mid-late 90s long before numpy and vector algorithms would have been available.

I suspect it’s more likely to be something like passing std::string by value not realising that would copy the string every time, especially with the statement that the mistake would be hard to express in Python.


Everything is new to the uninitiated. :P

For a real world comparison, the Perth desalination plant claims ~4kWh/m3.

> could save up to 63 billion gallons of water annually

To put it into perspective, 63 billion gallons is 193340 acre-feet, which is 0.5% of california's water use (a bit under 40 millions acre-feet). That's a tenth the water consumption of lawns, which is 1/15th the water consumption of agriculture.


Or about 4 hours of Mississippi River discharge.

But how many football fields?

A football field is 1.32 acres, so it's 146470 football-field-feet.

Gaping holes seems unlikely, more loss of detail or shifted colors.

You can experience something like that by using plugins which simulate CVD / color blindnesses.


Even proving your identity to a government entity is non-trivial, as can be seen by the administration trying to use that as a new poll tax.

When I needed to get my newborn daughter's social security card I went to the local SS office, only to be turned away because I did not have an appointment. So I went home, finally got an appointment after an hour on the phone, trying to explain why I didn't have her SS card (apparently "it never arrived" did not compute), went back the next day with my passport card to provide as proof of identity. Only for them to say "we don't accept passport cards as ID. We can use your license though!"

Baffling.


> the US government is too corrupt and intentionally ossified to react

The trump administration is not too ossified to react, it's in full support of. It dropped two investigations into polymarket mid-2025, and polymarket is crypto-adjacent, a field which the trump family takes full advantage of.


> Obviously this is a horrible use case, and I'm not sure if such websites actually exist or are just rumors.

polymarket has an @died tag, which I assume is for betting on people's deaths (I never used the site, and it's currently inaccessible) given apparently someone recently made half a mil betting on Khamenei's death, and a cool billion was traded on bets on the timing of the bombing of iran https://www.npr.org/2026/03/01/nx-s1-5731568/polymarket-trad...


> and a cool billion was traded on bets on the timing of the bombing of iran

Oh, trump made some money?


nit: The article you linked says half a billion, not a billion.

Death markets are banned in the US. Personally, I tend to think of this as a crypto problem, not a prediction market problem.


It's also fundamentally something you can't really do properly in crypto. You need a central authority to decide if "thing has happened". There's no way to properly incentivize accuracy in cases where the majority of stake benefits from an inaccuracy.
