Hi Alan
If the Chipmunks were at Scampton for Air Cadet Annual Camp AEF flying then they might well have been 'borrowed' from other Chipmunk operators for the duration of summer camps,if they were station 'Hacks' they might have been operated by the Station Flight or VASS/VASF.

it was a Monday back in 1969 - I was on my ATC annual camp at Scampton. For the start of the weeks activities I went flying in Chipmunk WK577/V and was first aircraft movement of the week.
