產品介紹
Leonardo da Vinci was a prolific inventor and artist who had a keen sense of the world around him. While most of his flying
machine drawings illustrated an attempt to mimic the wing movements of birds, he made one drawing of a helicopter type
flying machine, which he called an aerial screw, since in his vision it would have screwed into the air.
