The word helicopter comes from two Greek words: helix, which means spiral and pteron, which means wing. Leonardo Da Vinci called it the helixpteron which means spiral wing, and that's how we got the word helicopter.
The helicopter has many nicknames such as: chopper, eggbeater, whirly bird and also flying windmill. Unlike most airplanes, the helicopters don't need a runway. Helicopters can fly safely at much slower speeds and lower attitudes than other aircrafts. However they cant fly as fast as most planes. Most helicopters cannot exceed 2oo miles per hour.
