Thing,
Yep My Gliding Certificate is No 87198. The "courses" at the "Centre" were supposedly Joint Service Adventure Training Glider Courses (JSATG). The course I did, when I went solo was one of 12 students, 3 RAF, 3 Army and 6 RN/RM. After only one trip all 6 RN lads decided they had had enough adventure and wanted no more. That left six of us with a similar number of aircraft and instructors. We slept in a hangar annexe on standard beds. What a week. I found later that as a SNCO Airframe tradesman, I could be quite useful to the Centre so could usually get a week down there to do some servicing for them. A mornings work was often rewarded with an afternoons free flying. Great place, great people.
