Love all the films discussed here, so here is my 2 pennath,
BoB - Awesome! Excellent flying scenes, and plot lines, love it to death.
12 O'Clock High - Never Seen will have to watch.
Memphis Belle - Bloody Brilliant, awesome - Especially as it was filmed around where I used to live and can see the Church where I was Christened.
There is one addition that I would like to add, I know it is not a Film par se but it is a Mini Series called
'Piece of Cake'. The book is awesome as well if you get the chance to read it, written by Derek Robinson. He also wrote Goshawk Squadron about a Sqn of SE5a Pilots in WW1 and what they got up to, it's a scary, funny and heart wrenching Book, if you get the chance read it! It will scare the crapola out of you.
This mini series is a cracker, am gutted that I can only get the DVD in Region 1 and NTSC
