It would be right to state that, with the successful flight of the XR-4 in the summer of 1942, the helicopter became a reality in the United States.

Aeronautics was neither an industry nor a science. It was a miracle.

If you are in trouble anywhere in the world, an airplane can fly over and drop flowers, but a helicopter can land and save your life.
