Got to agree with Waco - Appointment In London, with Dirk Bogarde, is perhaps one of the best overall films about Bomber Command. The flying sequences are nothing special and the storyline is rather hacknyed - Wg Cdr is pushing to do 'just one more' so he can get in his 90th sortie and get posted to a ground job; Group say no but he manages to wangle himself on a Lanc full of 'odds and sods' including the ubiquitous USAF exchange officer (who incidentally has been banned from flying on raids by the USAF), Master Bomber gets shot down over the target but Wingco saves the day...and returns to ensure his crew make thier 'Appointment in London' to pick up tea and medals at the Palace. The film is dedicated to those crews who did not manage to make their Appointment In London - nice touch.
However, the film has a great period feel and for those with an interest in Bomber Command it is a must see. The Mess Party sequence towards the end of the film is very moving and poignant.
