how do some planes disintegrate when crashing into the ground?

Question

Is it all still there, just in tiny pieces?

In: 1

Answer 1

Essentially. The impact and heat breaks down whatever the plane is made of. So technically much of the same matter is still there, but broken down into the composite elements or compounds. The rest is ejected into the atmosphere as smoke. There will likely be chunks that can still be identified as parts of the plane
