Anyone who want's to know the history of this event has to watch the whole thing. It's the one Doc. of The Battle Of Britain that I go by. It gives details of listening to German pilots while being held prisoner without them knowing witch is interesting. Things about the Royal Navy, German S Boats ect. Civilian interviews from both sides. It's not the usual one sided perspective that you always see on the History Channel....Spitfire is your girlfriend for example.
