There's a new administration in Canada?
It was a Delta Airlines flight from Minneapolis so an American airline.
Perhaps you should look into the details of this story a little bit more ?
Plane crashes, overturns during landing at Toronto airport

I've probably posted a hundred messages here on MCAS! Most were downvoted to hell. The actual 737 pilots I talked to agreed with me, nobody else did. Classic Gell-Mann Effect. The only truthful account of the crashes is the official NTSB report. The 737 is an electric drive, with a manual backup. The 757 is a scaled down version of the 747's dual hydraulic drive, no manual backup. More efficient wings and engines obs…
Oh I was an aeronautical engineer (BS, MS aerospace engineering, concentration in fluid mechanics) for 8 years. Any pithy explanation of aircraft flight/engineering concepts that I post gets downvoted or ignored. Better yet, sometimes a java programmer tries to mansplain it to me in a worse way.

Yeah, but the whole point here is that the engines are very specifically designed to break off in a way that preserves the integrity of the wings . The integrity of the wings is a function that supersedes just about every other possible thing on a plane. You can safely land without any engines. You can safely land without hydraulics. You can safely land without gear. Without wings, a plane is a brick.
Indeed. And maneuvering speed V_A is designed such that as long as you don't exceed it, you will stall before breaking the wings off in case of turbulence or full control deflection.
I think you mean Vne?

> It's also much more pleasant. And much slower. Most people prefer shorter discomfort over a longer one. Also sometimes more expensive because train service is much more monopolized due to the need for infrastructure betweem stations.
Granted the lines are a natural monopoly. I don't see why the usual regulatory approaches shouldn't work. The government could even provide the infrastructure similar to highways. > sometimes more expensive Examples? Because that seems patently ridiculous on its face given the differences in energy requirements. There are plenty of places with functional rail systems to compare to. This stuff isn't rocket science.
Prices have little to do with cost when monopolies are involed, that's the point.

Flight from Frakfurt to Paris: options as low as 76 €
This isn't a 100% fair comparison but hopefully serves to demonstrate the absurdity.

So are you saying that the root cause of this crash (and the others I suppose) is something that happened in the last 4 weeks?
I cannot imagine the logic of that, so not sure why that response. What I was referring to, is the potential for state actors to breed fear re: air travel. It would be crushing economically, and create general disarray via distrust of core services.
Ah, well state level actors are another thing altogether, and would definitely have the effect you mention; a general distrust of air travel would be quite disruptive, and not in a good way. It is certainly worth considering.
But the simplest cause I see so far is piling-on job-termination stress onto an already stressed-near-the-limit air traffic control workforce, and near-eliminating enforcement of maintenance regulations. Better yet, the results will be totally stochastic.

That is indeed absurd, and I would argue a clear regulatory failure. Thank you for the example though. That is pretty wild.
Still, there's a decent chance I'd personally choose to pay that premium for the comfort afforded by train travel while nonetheless being disgusted by the broader situation.

The standard time for evacuating an aircraft that has to be demonstrated for certification purposes is 90 seconds with only half of the exits usable. It generally helps that the fire is (at least initially) outside the cabin most of the time. But yes, I wouldn't bet on conditions in the plane staying survivable for 90 seconds in all cases.
Sounds like plenty of time for me to get my bag, pull out my phone, and start texting

In the air. If the force applied is not the normal force expected from normal use it might be intended to snap off.
This is like suggesting that a boat's hull is designed to snap off in the event it encounters unexpected forces outside the water.
Parts of the boats are def made to snap off when unexpected force is applied.

One of my attendings during residency was Kenyan. In the bush, pediatric anesthesia was lido until they seized. At that point, you knew they could not feel anything.
This is insanely wonderful and amazing!!!!
As he put it, “cardiac-wise, they were very stable - no arrhythmias.”
