I know - contradiction in terms - but clearly there's a stealthy UH-60 - so why not try it with the big brother...?
On occasions when a singleton or pair of Chinooks can be spotted flying over Sydney, am always struck by how quiet they are compared to the UH-1Hs we had in NZ.
You could hear the blade slap for miles.
Living about seven miles from Odiham, with Chinooks passing over the house virtually every day, they definitely ain't stealthy. The internal doors in our house start resonating a good minute or two before the helicopter itself is audible. Maybe they need IBC* to cut the noise down? Would it work on a tandem rotor?
