RAF Upavon had a families day, the OCU was there with our aircraft that had to be hangared out of the way, during the show a casevac came in so a Puma was pulled out and down the taxiway, it was then cancelled so was towed back, just as we got to the hangar it was on again, so we turned round and set off again, over the radio it was announced it was cancelled so we turned around yet again and finally pulled it back into the Hangar. Closing the doors the RAFP who had been clearing the crowd came over and asked why we tow it back and forth across the aprons. "To wind up the starter motors" we replied... " Oh thanks" he said as he wandered off.... I do still wonder if anyone has finally told him the truth.
