If a Space Shuttle tile deorbited on its own, what percentage of it's mass if any would still be in one piece if and when it reached the surface of the earth?
The question was inspired by one of the comments on this question: Is there a very light material that could deorbit without burning up? specifically: "Trivial example: A properly-shaped piece of the tiles used on the Shuttle. – Loren Pechtel May 3 at 5:22".
Also inspired by this comment: "The question is flawed--nothing can possibly shed heat fast enough in the fire because there's no place to shed it to. Surviving the fire is accomplished by deflecting as much heat as possible (carried away in the shockwave) and slowing the entry of what gets through enough that you don't cook before it's over. – Loren Pechtel May 8 at 0:47" to this question: Is there a very light material that could deorbit without burning up?
