If you want more info about how the War Lover B-17s arrived in Britain, try and get hold of a copy of Martin Caidin's "Everything but the Flak". I don't doubt there's a touch of exaggeration in the telling but it's still a cracking read!
Incidentally, I chanced across a video the other day which shows a 1960ish Tiger Club display probably at Redhill - including a parachutist exiting a crazy flying Tiger Moth G-ACDC at relatively low level - pretty sure that would have been Mike Reilly who died doing a drop from the B-17s into The Channel while filming The War Lover. See if I can find it again...
