Wellesbourne Mountford (EGBW) in Warwickshire!
1. You can fly direct from the US to nearby Birmingham (BHX) airport.
2. Wellesbourne is in the heart of Shakespeare country and is surrounded by pubs, villages and close to the Cotswolds.
3. The aerodrome is 100% GA and very friendly.
4. There is plenty of unrestricted airspace nearby, although to the north and north west lies the Birmingham Control Area.
5. See
http://www.wellesbourneairfield.com/ for full details. It also lists nearby accommodation!
6. The Touchdown cafe serves good food at good prices - and is favoured by pilots, local motorcycle enthusiasts and 'British Bobbies' alike!
7. If you're lucky, you might even see the Vulcan taxying!
I would avoid the expensive South East of the UK as the airspace is much more complex! But do remember that the cost of private flying is considerably more expensive in Europe than in the US!
(I have no commercial interest in Wellesbourne - this isn't a free advert, just a plug for an excellent little aerodrome in the heart of England!)
