> is there any remains left

If there is, seems they're deep under the ground as it nosedove straight into the ground and essentially disappeared, the crater showed almost no debris at all. People been guessing on reddit that everything just got "instantly pulverized" which I doubt somewhat, the shape of the frame is perfect for it shooting into the ground so I'm guessing they'll spend some weeks digging and eventually find the wreck.

Edit: Since I can't respond to my children:

> This kind of impact in fact has tendency to turn aircraft into powder

How often? A similar crash that comes to mind is https://www.washingtonpost.com/transportation/2023/06/05/dc-... where they did recover actual bodies, even if the impact was near-vertical and seemingly faster than this case.

What specific cases are you thinking about where everything "instantly pulverized"?

The crater shows the road was destroyed. Aircraft skins are much thinner and less robust than road coverings.

Well, just looking at the article, I see trees, which tend to slow things down and can cause a plane to break up.

Mythbusters did this with a sled going "only" 650 mph and I would call the result instantly (but not entirely) pulverized:

High-speed camera footage of rocket sleds and fuselage testing is fascinating stuff.

You can see the macroscopic deformation fail to transit the body of the impacting object with enough speed to make gross deformation happen as it collides. The front of the rocket body is literally turning to a vapor at the impact site, and the tail assembly is 100% fine.

Er, no. You’re greatly underestimating or misunderstanding the forces involved here. “Instantly pulverized” barely even begins to describe it.

In the video in the thread, it seems to go from fully extended airplane to pancake in about two frames, which is, again, harrowing, horrible.

It's basically airframe to dust in three frames, so maybe a 1/20th of a second. The moment of impact would have been mercifully quick.

Nerve impulses travel at about 120 m/s, max, and that's along long myelated runs. Cohering raw pain signal into the experience of pain takes at least 150 msec according to the best measurements we have on the topic.

The vertical speed of the plane alone at last reported speed indication exceeds the speed of neuron transmission along myelated nerve tissue. This impact event is mechanically impossible to feel.

Unfortunately, even at a descent rate of 30,000 feet per minute you've got a full minute to anticipate the impact before you don't feel it.
