If you have a spare bedroom you don't know what to do with, why not make it into a giant flight simulator! This guy in Coventry, UK, did that and hopes to make a business of it (check links in story for his web site). I especially liked this quote from the interview when he was asked, by the writer, what else he keeps in the bedroom:

JD: "There's no room for anything else—
that's why my wife had to go!"
Anyway, here's the link:
