Bruno Vassel recalls how the control stick broke off in a glider pilot's hand and how that pilot landed the aircraft safely (using rudder to turn and trim to control speed).

Another favorite scenario is 'one spoiler stuck open'... the pilot opened the other spoiler to match and landed promptly.

Spoilers frozen shut... slip to land.

What else breaks and what if anything could be done about it?

Didn't ASCSC's SZD-50-3 PUCHACZ, lose a rudder at Warner, land and get back in take-off line up before someone noticed a missing rudder?
