That makes a lot of sense Ken. I've flown in a Blackhawk and a Chinook in recent years, and the rotor wash is pretty incredible at just a grounded idle. Each time we were cautioned about firmly securing loose items before nearing the aircraft - especially items we might not consider "loose", like hats, sunglasses and cameras.
I'm really enjoying all this video and photo documentation of the operation. Great insight - and just fascinating to watch.
