"...I wonder how many people out there know that the British Royal Air Force used the B 17 as well ?? They had two squadrons of mixed B 17 F & G types
I seem to remember there was an RAF song with the chorus:

So prang the bloody Fortress
Prang it good and strong
We'll have to prang the Fortress now
The Hudsons are all gone.

The only verse that I can recall is

The Gunner in the ballock
does not have very much room
But the Doctor says that he's got more
Than he'll have in his tomb.

Unfortunately I can't remember the name of the tune.

Just my two penn'orth.

Walrus.
