Whether it was a swiss, an american or an african pilot who has developed this technique... I don't care about that.
Fact is, it has a lot of advantages over the nose & collective down method, since you will not be able to do that maneuver in the final approach segment, where the probability of a VRS is the highest.
Why should we teach and learn a method, which will destroy the helicopter?
If the "other" VRS recovery is effectively controlled and reflexively like the introduction of an autorotation, we will be able to prevent a lot of this sad accidents.
