The thing is, this aircraft is to be a Black Hawk, not Chinook replacement. It would have the penalties of the CH-47's height but not the lifit and volume benefits. Also, the Chinook has maintenance platforms built into the housing of its aft rotor. How do people get to that upper rotor/hub without some pretty tall scaffolding?
