Wing Cmdr John Ayshford was the uncle of an old girlfriend of mine, he is sadly now deceased, and I spent many happy hours talking about his flying years with him. In his younger days he had been a Meteor display pilot and he recalled one incident where he was so exhausted at the end of a routine that a maneuver requiring him to fly down the runway and perform a low level roll resulted in him rolling inverted and then staying there (a hesitation roll perhaps ?) - he flew down the runway unable to roll upright until out of sight of the airfield. On landing he exited the cockpit somewhat embarrassed but was met with cheers from the crowd who thought his inverted flying was amazing.....
RIP John.
