While reading this thread I suddenly thought of the Biggin Hill Air Fair video that I made available to the forum.There is some great low level flying video footage as opposed to photographs on this tape, as those who have seen it will agree.
The primary action is of Ray Hanna in MH434 ,and Pilatus P2 G-BJAX and this is well worth seeing (You couldn't fly lower without lowering the undercarriage !!).
Unfortunately the tape was never returned,although i still have the master copy.If anyone knows where it is and anyone else wants to see it,then get in contact with whoever has it and get them to send it to you.
It really is worth seeing !.
