I remember that Gazelle, it lived in A shed what I was a Farnborough apprentice circa 1988/89. There was a placard in the cockpit saying "It is prohibited to crash this aircraft ", or words roughly to that effect. I don't actually recall ever seeing it fly, but recall being told that it was mostly flown by the station commander as his private "hack" - that may of course have just been ground crew scuttlebut.
