Saw one of these guys up at Felker today doing 1, 2, and 3 wheel training on the ramp, part of which involved a lot of what appeared to be backward taxiing (it wasn't clear if the taxiing was intentional or not) ... it certainly looked shit hot, but can anyone tell me why you would do something like that? Buildups for 1 / 2 / 3 wheel landings, perhaps?
Chinoks have no slope limits and can put down in some unusual places. A second reason is that the dual rotor design of the Chinook allows it to rotate around either rotor, so again, they can get into some unique landung situations. I think many of us remember this
