The helicopter has really changed the way that many things are done since it was invented. Traditionally, the helicopter has a rotor or two up top and a tail rotor. The upside to the design is that it can take off and land vertically. The downside is that a rotorcraft isn't as fast as fixed wing aircraft. Eurocopter has announced that its X3 Hybrid combining rotors with propellers has hit a speed much higher than normal helicopters are capable of. The X3 hit speeds of 232 knots or 430 km/h in testing. This will be a fantastic aircraft for rescue mission where speed is critical.
