No - it 's not a secret surely? The FI Tourist Board have/had links for tourists on to how to book RAF flights from Brize for at least 10 years - times, dates, gate to arrive at, paperwork etc. Some people on here assume that if it's painted grey it's a secret like Ultra.
A mate of mine is planning a trip this fall (well spring down there) and I was trying to help - I was last down there before they'd finalized the Second Flight
FYI not military but I am bound by the Official Secrets Act on certain work
