The one I always hoped was true was the tale of a Herc load of paras returning to UK from some exercise or other. The troops were not on their best behaviour so on landing at Lyneham the Master Loadie decides on a bit of payback and has his human cargo doubling around outside the aircraft whilst waiting for the pax bus. As is the case this takes forever but finally it arrives and the paras (no doubt not even out of breath!) board the bus. Last on is the Sgt Maj who takes the Loadie to one side and says, words to the effect of, no problems with the 'punishment' but perhaps next time he could fall the colonel out.
