I also did my Enstrom training with Dennis/ Tony Clarke at Booker ...in 1983, but knew him from the mid-1970s....simply splendid man. He even restored my Grandfather Clock for me at one time. I was also fortunate to witness some of his display flying ,including at the world championships in the UK when the Enstrom tail rotor control cable broke and he did a perfect run on landing.
So many memories......so many anecdotes...
