Some years ago I heard an Upper Gunner on a Lancaster
Bomber interviewed about his experiences during WW11.

On one flight into Germany he asked to lef his position to use
the toilet I belive they had an Elsan on board. The reply came
back, "Permission refused!" As they were close to the target.
The mission was completed and on the return journey the
Captain remembered the dilemma and called the gunner and
gave permission for him to leave his turret, he replied "Don't
worry its set."
