The futuristic-looking Sikorsky X2 helicopter features a double-decker, quadruple blade design and “the designers want it cruising at over 285mph by the time they’re done — over 100 mph faster than, say, an Apache attack chopper, which tops out at around 175mph.” Video after the break.

It’s also got a six-bladed prop in the back, and it’s all designed to give the craft excellent handling even at high speeds.
