Sikorsky X-2 does 250 knots???

Don't know how I missed this.  From ASDNews.com.

The speed, reached during a 1.1-hour flight, is an unofficial speed record for a helicopter. The demonstrator also reached 260 knots in a very shallow dive during the flight.

"The aerospace industry today has a new horizon," said Sikorsky President Jeffrey P. Pino. "The X2 Technology demonstrator continues to prove its potential as a game-changer, and Sikorsky Aircraft is proud to be advancing this innovative technology and to continue our company's pioneering legacy."
