Thanks UNCTUOUS,
It seems like that link was just waiting for me all come along and ask the obvious !!
No doubt the powers that be have tested the idea, but I can't help but think that a boot full of opposite pedal could help the situation. Your diagrams say that its unlikely, it probably is, but could the tilting forward of the disk and the subsequent travel help to remove the disk from the Vortex Ring State. I guess similar to the flying out (forward) of the VR in a conventional helicopter. Even in the extreme case of the aircraft rotating 90 degrees (or more), it will effectively remove the condition.
It's nice to have all this time to think about it - I don't suppose that 2 seconds is enough for a reaction to take place after recognition etc anyway.
Further testing maybe ?
