The VASF guy was seeing in a Belgian Merlin. On finals there was a mixed up message and it was thought that there was a VIP on board - rush for white coveralls, Staish into No 1s etc. The guy put the chock in then backed out into the prop. If I remember correctly he lost a bum cheek but it missed the hip and the muscle. - No VIP on board.
About that era a UAS Bulldog stude had a lucky escape. Stude running change. First stude got out onto the wing, stumbled and fell forward. Prop caught his helmet and knocked him down and clear. That split second as he realised he was falling into the prop disc must have been hell.
