I am going to check the flying machine that I have designed, and it will allow me to fly great distances in a few hours. I showed Leonardo my project and he was impressed with the way I solved the machine's support in the air and its movement. At the moment Leonardo devotes all his time to designing weapons for the Medici. I can't count on his help. I have discovered that in the air there are two kinds of very thin alternative layers superimposed and formed by characteristic elements.
