Sweet!  That would be *so cool*!  Imagine sitting out on the deck
looking up at the full moon, and all of a sudden it starts falling

(tides, crust stresses, etc) and the fact that the earth is still
rotating, how long would you get to watch the moon before it landed
on you?  The first person to answer will get a cookie(*)!

I get 1 hour, 13 minutes.  Or 2 hours, 26 minutes.  If I could remember the
derivitive of y = x^2, I'd be more precise.
