and movement he made detailed drawings of birds wings most of all he had a dream to design a machine that would let human beings fly like birds one of Leonardo's designs for a flying machine showed an enormous pair of wings joined to a wooden frame According to the drawings the brave pilot would lie inside the frame and move the wings up and down Leonardo also drew a design for a glider this was much simpler and people have recently built and successfully flown it with one small change to the original design other flight related designs by
Leonardo were for a helicopter and a parachute Leonardo was so many things artist musician architect engineer Scientist and inventor today he is usually best known for his art including two of the most famous paintings in the world Mona Lisa and the Last Supper however centuries ahead of his time he imagined and designed a huge range of inventions surely he must count as one of the greatest inventors ever track 9.12 Let's talk unit 7 to 9.
