Re: How many Shuttles could have been kept operative..
Thumbs up for "Riding Rockets".
My copy was recursively lent out, and endet up in the hands of a NASA engineer who knew most of the characters in the book personally. After falling of the chair laughing, this guy then ended up buying 10 copies to give to all of his friends in NASA.
A VERY worthwhile read.
(Oh.. and DID get my copy back in the end)
