Speed record: Eurocopter X3 hits 255 knots: "Eurocopter has announced a new pair of speed records set by its hybrid helicopter demonstrator, the X3. Piloted by Hervé Jammayrac, the X3 reached a level flight speed of 255 knots (472 km/h) over the south of France on June 7, eclipsing the 250 knots (463 km/h) set by Sikorsky's X2 demonstrator back in 2010. The X3 reached 263 knots (487 km/h) several days beforehand, achieved during a dive rather than level flight, also besting the X2's record in descent – by a single knot."
