Without wishing to sound rude, I think that the name of the Labrador may soon become the last of your concerns.
I am led to believe that the 'real' story behind the Dam Busters raid may well bear little resemblance to the film. Recently unearthed documents suggest a different, less impressive, story, which might give cause for the history books to be re-written.
I can't personally state what this evidence is, but I know that a book on the matter is being written by a respected historian, and that he has access to a range of previously secret after-action reports and 617 Sqn. documentation.
It might be worth holding fire on ITV until a real target appears!
