Just for the record (and in response to Paxboy's question), Northolt will quite happily take 737/757 and A320 types. can't quote useable payload/range etc but certainly within Continental Europe.
Regarding the C17, it would be fair to say that the sky does go rather dark when one of those approaches this sleepy hollow. Unfortunately, the RAF haven't done it yet, until now we have to rely on our American colleagues to provide the entertainment.
