It had seemed a good idea at the time, flat field, bigish glider, pull it up with another plane.
As unofficial gang photgrapher, I was there to record the attempt.

Large two channel glider had a tow release fitted, line was attached to tow plane, maybe the choice of tow plane was not the best, but well sometimes you run with watcha got.
Is a midget mustang a good tow plane?

Well the first flight went OK, not too high, the release worked fine, down she came to a safe landing.

OK, lets go for a bit more height.
The problem is it gets a bit more difficult to judge things as they get higher, things get a bit stressy, the line starts to jerk a bit, following the tow plane gets harder.
Suddenly a wing folds, tow release works, luckily.
