Flying Experience de Havilland Tiger Moth - West London Aero ClubWest London Aero Club
White Waltham has Chipmunk and Tiger Moth flights, and is a just plain enjoyable place to hang out when not flying - as well as being just a few miles from Heathrow.
If you're passing, shout - I fly from there and would be glad to chew the fat over a coffee. (No, beyond checkouts within a syndicate, I'm afraid that I'm not one of the local instructors.)
