Hi Pál,
in the description to the video Spin Failiures you wrote that he goes into a deep, fast spiral.
I would say it's more like a unintended SAT - produced throug the cravat. Even the sinkrate is not very high. Only the rotation is very fast.
And then always the same problem occurs: When the pilot pulls his emergency, it will be cashed by the gliders lines.
Do you, or anyone else have a good idea how to prevent a situation like that, seen in the video? IMHO there is too much height-loss between pulling and the stopped rotation.
Maybe even throwing the chute towards earth?
