I will be in Southhampton on business in June with a couple of free
days, one thing I like to do when that happens is rent a plane and
instructor at a local FBO for sightseeing flight. I've been able to
find those types of resources easily in the U.S. with airnav.com. Is
there a similar resoruce for Europe? Or can any of our European
friends clue me in on if this is even possible, or whom to contact?

Thanks!
