Thought you all might like to see this photo, taken by a 32TRS RF-4, recently donated to the ARG Archive at Alconbury:

The time period of the photo is 1969-72, so could just cover the Battle of Britain movie filming, but I must admit when I found it while going through a bundle of practice target photos it was a bit of a "Final Countdown (1980)" moment...

All the best,
PB
