When I did my gliding course in Feb 1968, it ended with three solo's. I was told that I had to do at least one left tun, and one right, in whatever order to qualify for the A and B certificates.
However, this might have been an evil staff cadet winding up a nervous student! In any event, it was a fantastic experience for this 17 year old. At the time I was probably the only one in my schooll of 400 or so to have done something like that.
I can also remember 611 doing a 'longest weekend' session in the early 1980's, when they tried to make 611 launches.
When I read your initial request, Dave, did wonder if you were going to do a ' that was then, this is now' comparison.....
In any event, thank you from this ex-student to all who made it possible then and now.
