I have a question about the history of rotorcraft. How did the helicopter come about?

The first helicopter was invented by the Wright brothers in 1903. The Wright brothers were the first to fly a powered airplane. They were inspired by the flight of birds. They wanted to build a machine that could fly like a bird. They built a machine that had two wings and a propeller. The propeller was powered by a gasoline engine. The machine was able to fly for a short time, but it was not very stable.
