Thanks. I was thinking of a couple. One was a film on the Secret Blue Silk Doppler on the Canberra. The other which I would like to watch again was one on Hunter recce. It showed route planning, turning on a 6d, and track marking. Then the flight. He flew passed a bridge and rattled off the description, something like, "flat
deck bridge, two lane, 8 span . . "
Very impressive to an impressionable 18 year old. Never occurred to me at the time that the chatter could have been a scripted voice over from the film.
