Thank you for posting. A very emotive video, and compared with the Buccaneer video talked about on another thread, this shows just how much of an easy target these Lancaster's were (oh, and yes,I could hear the music in my head too).
I have mixed views about the dams raid, and it's success depends largely on what the outcome should have been (i.e. tactical/strategic/morale (both sides)/propaganda), but have no doubts whatsoever on the crews involved, and am shrunk with humility by their efforts on such a difficult and almost one way mission!
