This is me with Mike Charity (centre) covering the Falcons Parachute Team, air to air, has they left a Hercules. It was so windy, because the door was open, I could hardly keep the 300mm lens I was using trained on the back of the Hercules. Combine that with slow motor drives, film, slow focusing lenses (I may of focused manually),  I do remember nearly missing the action because once they formed up and jumped it was all over in about a second. Didn’t have the luxury of 9 frames per second in those days.
