The helicopter saw incremental success in many countries, and the following short review will highlight only those whose contributions were ultimately found in successfully developed helicopters. For the answer, we turned to Roger Connor, curator of vertical flight in the aeronautics division of National Air and Space Museum. the helicopter is the Bell UH-1 Iroqouis, better known as the Huey.
