According to Wikipedia: "The Messerschmitt-Bolkow-Blohm Bo 105 is a light, twin-engine, multi-purpose helicopter developed by Bolkow of Stuttgart, Germany. It featured a revolutionary hingeless rotor system, at that time a pioneering innovation in helicopters when it was introduced into service in 1970. Production of the Bo 105 began at the then recently merged Messerschmitt-Bolkow-Blohm (MBB)."
