kicking the maxarets
Herod, you are correct, it was Rocket Sox kicking the maxarets but BD was in the galley asking the girls for a cup of tea and a buscuit with his usual "hows you, hows you", and failing to push the isolating pin in.
Result - brake release due to lack of pneumatic pressure - and the wonderful sight of our handlebar moustached hero hanging on to the drag strut with smoke pouring from his shoes as the aeroplane rolled gently back into the catering van.
I have a cartoon somewhere whch I will post if I can find it.
Happy days
