When gliders fail in flight, but pilots manage to land

Not sure everyone understands how the rudder control system in most of our ships, works. Typically, a cable on each side from the rudder to the pedal with a spring at each pedal (to keep the pedal erect). If a cable breaks or becomes disconnected, the pedal on that side will be pulled forward by its spring........ends up flat on the floor! Meanwhile, the spring on the other rudder pedal will pull in uncommander rudder! Sensing this, the pilot tries to correct with opposite rudder, but that puppy is flat on the floor! Next, the pilot applies opposite aileron before the uncommanded rudder gets out of hand. This works, but the ship is now flying in a full slip!
This is exactly what happened to two pilots flying an ASH-25, a few years back and they were on the ridge! The PIC flew away from the rocks, in a full left slip and made a radio call giving his location, situation and intentions (bail out). Hearing his call, I thought for a few seconds, then asked if the rudder pedals in the other seat were working? Anxious seconds later, a much relieved voice reported that, in fact the front seat rudder pedals were working normally. They headed for the nearest airport with the front seat pilot holding enough right rudder pedal to keep the rudder near neutral.
Something to add to your bag of tricks,
