Rotorcraft are more commonly known as helicopters. While they are one of the most common aircraft in the skies, they are so distinct from jets and general aviation aircraft that they are considered their own sport.
The theory behind a helicopter can date all the way back to the drawings of Leonardo Da Vinci. The first practical helicopter followed close on the heels of the Wright Brothers' first flight; French inventor Paul Cornu made the first rotorcraft flight in 1907.
The Helicopter Club of America assumed sport aviation responsibilities when it was formed on January 13, 1979, at the annual convention of the Helicopter Association of America. HCA fosters and promotes professionalism and helicopter sporting events throughout the United States.
