BG.
Hope you don't mind me calling you BG !!
Your profile says you were a 617 ATC GS Instructor. 617 were based at Bovingdon.
A quick Google search.
I found your account of the Buchon/Mustang 'wolf in wolf's clothing' hybrids.
The rest was easy.
Splendid account you posted about the making of the films.
Grubby.
Ahh.. also best not include too much info in the properties of your pictures !!
