I think that value should be 100 ft/sec. Mach one is about 600 Knots = 1
NM/Min. One NM = 6,000'. Divide 6,000 by 60 (seconds in a minute) and
you
get 100, not 1,000.

NASA uses a sylized value of 1,000 ft/sec as Mach 1 at the very high
(Peak
Heating Region) altitudes.

I wish the people in the local cocktail circuit were more tuned in to
air & space. Then I could ambush somebody with this factoid.

Well, Dan you just have to wait till someone says, "Boy, we've been
having some hot weather recently!"

Whereupon you respond, "Speaking of 'hot,' did you know that at the
Peak Heating Region.....
