God, I was at Linton when much of it was filmed! Brings back memories... I didn't know your Dad, as his course didn't arrive until after I'd left (much of the filming was done in advance), but I did later know Martin Oxborrow quite well on Hercs. Of course, the staff at all the various schools (bar Brawdy, to which I never went - I did the Lossiemouth TWU).
I believe it was a comment by yourDad that caused the CAS at the time, Sir Keith Williamson, to rescind permission for TWU students (and indeed all junior pilots until 6 months into their operational tours) to live out. He wasn't popular for that!
Dave is well known to me from his brief sojurn at Virgin. A total star and a gentleman of the first order - and a Ppruner!
