Wasn't one of the solutions to this to use go with the flow and go inverted rolling in the direction of the dropping wing and fly out inverted? This might allow someone to avoid hitting the mountain when normal control forces are not sufficient to stop the roll.

This would be similar, though more extreme, to Karl Striediek's technique of banking in the direction of sink (dropping wing) to quickly get into the center of lift instead of trying to bank towards the rising wing, when trying t center a thermal.

Of course going inverted deliberately close to terrain is not a snap decision but need a lot of thought and best aerobatic instruction,

Thoughts?
