New Helicopter Promises to Be the World's Fastest

Sikorsky Aircraft's prototype X2 helicopter became the world's fastest helicopter when it reached a speed of 225 knots -- 9 more than the previous record set in the 1980s by a Westland Lynx. From the company's press release:

The X2 Technology demonstrator combines an integrated suite of technologies intended to advance the state-of-the-art, counter-rotating coaxial rotor helicopter. It is designed to demonstrate that a helicopter can cruise comfortably at 250 knots while retaining such desirable attributes as excellent low-speed handling, efficient hovering, and a seamless and simple transition to high speed.

Looks sleek. As long as they are able to keep the speed at the tip of the blades lower than the speed of sound they can reach higher speeds. good luck.
