I was tanking off a Victor once doing a conversion exercise where the nose gunner had to plug and un-plug several times. During one un-plug he (OK we) were a tad quick and put the HDU brake on.
'Step aside and we'll re-trail the hose ' came the Victor's voice.
We duly moved to the left (as we did in those days) and the hose wound in, wound out and promptly fell off!
Really pleased we'd stepped aside 'cos at the time it seemed like a waste of a perfectly good waiting position!
