Flight Time Secret for FAA pilots in UK
In the early 90s I worked at USAFE Lakenheath, flying Tromahawks, and Cherokees for the Aero Club there. All 'N' registered aircraft. We flew all over Europe teaching GIs to get their FAA licenses in UK airspace. Great time builder and all in the UK!
I have no idea what the deal is there now. When I was there Lakenheath and Upper Heyford both had aero clubs that hired British pilots with FAA credentials.
Good luck.
