　　man has always wanted to fly. some of the greatest men in history have thought about the problem. one of these, for example, was the great italian artist, leonardo da vinci. in the sixteenth century he made designs for machines that would fly. among these designs there was actually one for a helicopter. there was also another one for a parachute (降落傘). but these things were all designs. they were never built.

　　throughout history, other less famous men have wanted to fly. a typical example ws a man in england 800 years ago. he made a pair of wings from chicken feathers. then he fixed them to his shoulders and jumped into the air from a tall building. he did not fly very far. instead, he fell to the ground and broke every bone in his body,

　　the first real steps 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, a chicken and a duck. 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. on 21 november, pilatre de rozier and the marquis a arlande rose above paris in a similar balloon. their trip lasted twenty-five minutes and they traveled about eight kilometers.
