How amusing! After all, you've made the claim that a subsonic aircraft cannot penetrate terra firma, not me. Considering that you have failed to provide evidence on other things, underlines my point.
Did he really claim that?
I must not have been paying full attention...
However, I wonder how he'd explain the 3 foot deep and 8 foot wide crater in the tarmac that a P-51 mustang made when it crashed at the Reno Air Race last year...
Certainly, a P-51 isn't super-sonic. "Bad fast", but not super-sonic, and it left a big hole in terra firma...through the tarmac!
