I somehow repeated the event on the FX at Biggin Hill 1999
I recall that, was it really 12 years ago? I remember you had drifted down towards the 21 end; there suddenly seemed to be a fair bit of juggling at fairly low level going on, followed by a sudden set down with maybe a hop and a skip or two - and there the Enstrom stayed! Not sure the commentator was aware there was a problem.
