Leonardo da Vinci made a design for the now called helicopter. He called it the Aerial Screw. He never built or tested the Aerial Screw after he made the design and it's probably a good thing he didn't because now, we would know that if we used all of the extremely heavy things he did, it wouldn't fly.
