I was part of the emergency services team at IAT 93 and remember giving a thumbs up to a Puma as he taxied from North side and their was'nt a lot of space between the blades and the top of some engineering guys discovery. I then ran bout 1/2 mile to get keys and move it. Which for me,then and now, is a very long way. At the time the fireries thought they were looking for a dead Mig pilot!! A few beers were sunk that night!!
