True. Really big chunks might have a tiny percentage of the interior
survive. Of course, it isn't likely to be unaltered by the collision
(unlike small meteorites found here, which do have unaltered interiors).
And irons aren't so interesting. Are there stony meteorites that are the
product of hypersonic collisions on Earth?
Large impacts are as rare on the Moon as they are on Earth, but of
course any debris essentially lasts forever.

At what velocity do you think Canyon Diablo impacted?
I think we found some pieces of that asteroid.
