My early flying was nearly all launched by winch; the winches
in the 60s were pretty anaemic.
Nevertheless, the standard practice was to take up cable slack
till it was pretty straight, so the initial acceleration was
directed along the glider axis. this would remove the roll couple as described in the report.
More recently, experience at Bristol GC and the Mynd was like
a superbungee launch and I admit to some concern about the elevator
power to cope with the pitchup.

It would seem that initial acceleration should be moderated.

The PTT problem is unknown to me, but I presume it must mean
passenger temper tantrum.
