I seem to remember that it was Pontius Navigator who first brought this incident to light when the crew chief 'tripped over' what he thought was an air brake that hadn't retracted fully.
Know also of his re-fuelling exploits from the same source.
But would like to try and fill in gaps. Heard he was on the commissioning board at Biggin Hill for a posting but lots of blanks, and because of what I said before family ties unfortunately not as strong as they were.
