Hughes 500's story tells it best....true VRS is pretty scary and at best unpredictable. We do on occasion put an aircraft into it to demonstrate what it is about for a student or pilot that has not experienced it.....never, ever less than 6,000 ft agl. In my 38 years of flying, it is still the only air exercise that still gets my heart rate up.....
And Anfi.....let me know if you ever come to British Columbia.....I would be more than happy too take you out for a ride.
