I saw Chris Lackman and Jack Thompson display the week before at Finningley. I also recall (in light of the Abingdon incident) an article appearing in some journal somewhere by someone claiming that the display at Finningley was flown dangerously low resulting in a fierce reply from the Finningley Station Commander, Group Captain Pitchfork, who made it clear the aircraft never breached minimums throughout the sequence. A figure of 300' as the minimum (flown on this occasion) during the display, was given. I also remember reading in air clues a couple of years prior, that the actual minimum separation distance for display flying by such aircraft was, at the time, actually 250' Did the enquiry exonerate the crew, I seem to recall it did?
