In reply to Owen W-G:
Hi Owen.
My sister worked on a BBC shoot doing exactly this a decade or so ago.
It involved a peregrine and a BASE cameraman.
I remember distinctly that it was shot on Anglesey, so Gogarth?
I don't know whether it was a success and if so what the programme was called, but somebody at BBC NHU might have some recollection of it and its location.
