Re: Thanks, R.L.! ...And you too, Delbert. [N/T]
My reasoning is that in the sparse upper atmosphere there is not a dense enough medium to support a compressive shock wave... if it survived the friction there, it can then create the compressed shock wave and super heat the air before it ... pretty extreeme conditions...it explains why those that make it to the ground are so rare!
But anyway just want to say that is just my guess, not hard fact but just my opinion... I have no experience in that area.
