Sikorsky Commanche RAH-66 helicopter flying sideways-I don't know if other helicopters can do this. I do know the Commanche has a special tail propeller though.

Blackhawk helicopter-the ones that guard and hover AREA 51

Well, since I'm a sponsored RC Helicopter pilot from JR, I should chime up..
Helicopters actually have no 'concept' of forward...thats mearly a perceved idea. Helicopters (given enough tail authority), can not only fly sideways at speed (remember, its just the tilt of the main rotor that causes a change in direction), but they also happily fly backwards, and (esp. in the RC world, but a few newer models), can also sustain inverted flight-- by mearly changing the pitch of the blades from +6degrees (std. hover), transitioning to 0, then -6 (or more) degrees as the helicopter rolls (or flips) to an inverted position.
Typical reasons this isn't achieveable on most helicopters is due to 'coning' of the main rotos, where inverted flight causes the tail-boom to be chopped off (because of the bend in the blades)... certain military helicopters (and RC heli) do no exhibit as much flex, and can sustain inverted flight.
... I really have nothing important to say, was a cool video...

Taken from the door-gunner position of a UH-60 in Kuwait....
Sorry it's blurry, but we just came out of a 90 degree bank. In case you can't tell, thats a collection point for captured & destroyed Iraqi artillery.
