I agree, it is a phenominal series of events that cause it and the biggest problem is that if you don't react it increases in intensity exponentially.
I'm not trying to preach to the choir, but something I learned many years ago has served me very well when trying to explain the recovery procedures.
If you remember back to your boy scout days when you were learning about fire you'll probably remember the term "The Fire Triangle" which required three things, Fuel, Heat and O2. Think of Vortex ring state as having a similar 'must have' triangle. It requires three things, take one away and it doesn't exist, they are ROD in excess of 500 fpm, High power setting and an airspeed below translational.
As in the fire triangle, if you take any of those items away, it no longer exists. I know this was a little off topic, but if any of the younger less experienced guys out there can benefit from it, well there you go.
