I think the footage in question came from 'Farewell Bucc', a video made in 1994 by Videoage Productions.
It included some fairly spectacular footage from Gib and from the closing day(s), at Lossie and the 'airfield attacks'. Very unfortunately, the film crew 'forgot' to keep a log of which day or time different scenes were shot on, so no fingers could be pointed.
What's your personal interest Steve Bond? Were you involved / there / on Buccs?
