Hi all Interesting read, this thread. Suspending things from underneath a helicopter is actually fairly straightforward, legally, providing the aircraft is fitted with factory-fitted or approved aftermarket sling hooks, and the load doesn't exceed the load rating of the helicopter, and the combined weight of the load, pilot, passengers and fuel does not exceed the all-up-weight of the aircraft, and the performance of the engine(s) and rotor system on the day (variable on things like the weather) are within limits. The hoop is suspending from two slings, but I'd suspect that if one snapped the other one would be strong enough to keep things attached. They're using a longline to keep the hoop out of the downwash from the rotor otherwise it would spin like a top, although there would be some wind irrespective of sling length. Once in the hover the airflow from the blades tends to be fairly laminar, which actually helps to stabilize what's underneath, providing it's not shaped like a wing. A human on a hoop is about as unaerodynamic as you can get. Sure it's been mentioned already but as she sits on the hoop you can see her attach a d-link with a steel cable to her belt to prevent her from falling out. For those that are interested, the helicopter they used is possibly an AS530. They have a rather unique shape to their skids. https://www.aircraft...-Sale/62698.htm All the best Timmeh
