HORSEHEADS, N.Y., Aug. 27, 2008 – Sikorsky Aircraft Corporation today successfully completed the first flight of its X2 TECHNOLOGY™ Demonstrator, maneuvering the prototype aircraft through hover, forward flight, and a hover turn, in a test flight that lasted approximately 30 minutes.

The X2 TECHNOLOGY Demonstrator is designed to establish that a helicopter can cruise comfortably at 250 knots, while retaining such desirable helicopter attributes as excellent low speed handling, efficient hovering, and safe autorotation, combined with a seamless and simple transition to high speed.

Counter-rotating coaxial rotor helicopter... wow.
