I think the way it could be said, Rich, is that the VRS you experience in a properly powered helo is not something that will cause it to descend unstoppably or lose control. The crane driving test pilots at Sikorsky used to describe vertical descents until deep into vrs, then lifting collective and climbing straight up out of it. Done by professionals on a closed course, do not try this at home!

I got a great case of vrs doing short field landing OEI in an S-76 once. Engine cut at 140 feet, passed thru 75 feet at 50 feet per second rate of descent. Hit at 13 fps, bounced. Makes you shake the hand of the airframe designer, vigorously!
