Mobility today has become easier and faster than in past centuries. This was a result of technological advances resulting from scientists' research. Aviation, in particular, has seen dramatic innovations in aircraft engines, improved over past designs. What is striking in this field is how the idea of ​​a possible movement in the heavens was born. This is exactly what this paper seeks to establish. Beyond that, it will also look at the Air Mail Experiment and the advent of the United States Aviation Oversight Program (FAA). Air transport has evolved significantly. Great scientists have played an important role in setting the pace toward accomplishing today's work in aviation. Leonardo Davinci was the founding father of aviation. He will be remembered for being the first to think of and put on paper over 100 drawings of birds and mechanical flights in 1480, showing birds' wings and tails. The "ornithopter" was one of his designs of a bone aircraft engine from which the current helicopter was invented. Thanks to his works, the pioneers of aviation accelerated their pace and in 1783 the Montgolfier brothers discovered the hot air balloon. Its first passengers were a sheep, a duck and a rooster who were carried over a mile to an altitude of 6,000 feet. After this success the passengers became men. Between 1799 and 1850 Sir George Cayley, the father of aerodynamics, analyzed lift and drag forces and conceived the concept of air propellers, steering rudders for building gliders. He tested it with a guy flying it whose name is not known (phillip1999). George made improvements to his models and suggested that a fixed-wing aircraft with a tail and a propulsion system was all that was needed to make humans fly. In... middle of paper... in 1920. Other developments such as the radio communication system and control towers emerged. The government was deeply involved in funding research and creating regulatory bodies for airline management such as the Civil Aeronautics Administration in 1938. The aviation oversight program in the United States was later realized through these developments to drive developments in aviation. Works CitedPhillips, E (1999).
