Air Cadet Gliding pix in the 80s (pre glass)
When I saw my name in Airclues' post it sent me to the loft as well. I can confirm that we managed only three days flying that week. It stretched our time-filling alternatives and used most of our supply of old films but it also sharpened our efficiency on the days we could fly. I'm glad it worked out for you Airclues.
The most concentrated instruction we ever gave was for one chap who wasn't able to arrive on a week's course until the Friday. All the other cadets had gone solo so he had a glider to himself for as much flying as he could manage. After occasional breaks and mealtimes he was still coping in mid-afternoon on his 20-somethingth launch so the last three launches of the day were his triumphant solos.
Incidentally, Airclues, Peter Bullivant, who did your pre-solo check, went on the train Prince Andrew. If I can find out how to post pictures I'll track down some from Kirton Lindsey.
