The first Vulcan for 617 Sqdn. arrives at Scampton. Everyone turns out to watch it taxying towards ASF. Sgt detailed by crewchief to marshall it the final 50yards or so. As it turns to park, in between the hangars, the starboard wheels cut across the grass and sink! Thankfully a quick blip on the throttles and it clears, no problem. Who was watching the starboard side...Wing Commander OC Eng, Wing!
