Ah - yes, the famous Wattisham display teams. Most squadrons used to have (in 't'old days') a 'Wing-Ding' on a Friday afternoon, but Wattisham made that into a 'Ventral Ding' tradition. Much tittering on the senior squadrons up north, but if I recall correctly the first Wattisham squadron to groove the runway was followed a subsequent Friday by the other squadron repeating the 'unfortunate event', obviously not wishing to be outdone...............
I think the games stopped at that point.
