[2] Module 1 | The significant milestones and key events in the historical development of the aviation and air transportation industry.

1. **Wright Brothers’ First Powered Flight (1903):

The Wright Brothers, Orville and Wilbur, achieved the first successful powered flight in Kitty Hawk, North Carolina, on December 17, 1903. Their aircraft, the Wright Flyer, traveled 120 feet in 12 seconds. This event marked the birth of powered flight and paved the way for the development of aviation.

2. **World War I (1914-1918):

World War I saw the first significant military use of aircraft. Fighter planes and bombers were used for reconnaissance and combat. This period accelerated aircraft technology, leading to the development of more advanced planes, which later found applications in commercial aviation.

3. **Airmail Act of 1925 (Kelly Act):

The U.S. government passed the Kelly Act, which authorized the United States Post Office to contract with private airlines to carry mail. This act spurred the growth of commercial aviation by providing much-needed revenue for airlines and fostering the expansion of air routes.
