While not exactly brand new tech, one of the coolest displays at the Association of the U.S. Army's annual conference here in Washington was Sikorsky's X2 high speed helicopter. Yup, the actual helo used to test out Sikorksy's coaxial rotor designs last year. The chopper was a hit of the show, constantly surrounded by picture takers, including me. Enjoy these close up photos and a quick iPhone video of the chopper below the jump.
