man has always wanted to fly .some of the greatest men in history had thought about the problem .one of them .for example ,was the great Italian artist,Leonardo Da Vinci .in the 16th century he made designs for machines that would fly,but they were never built.throughout history,other less famous men had wanted to fly.an example was a mam in England 800 years ago. he made a pair of wings from chicken feathers .them he fixed them to his body and jumped into air from a pair a tall building .he did not fly very far .instead ,he fell to the ground and broke every bone of his body and rested in peace.the first real step took place in France,in 1783. two brothers .the Montgolfiers,made a very large "hot air balloon".they knew that hot air rises.why not fill a balloon with it? the balloon was made of cloth and paper .in September of that year,the king and queen of France came to see the balloon.they watched it carry the very first air passengers into the sky .the passengers were a sheep and a chicken .we do not know how they felt about the trip.but we do know that the trip lasted eight minutes and that the animals landed safely.two months later ,two men did the same thing.they rose above Paris in a balloon of the same kind .their trip lasted twenty-five minutes and they traveled about.
