The document provides a history of aviation from its earliest flights in the 1900s to regulatory developments in the mid-20th century. It notes that the Wright brothers began flight demonstrations in France in 1908. In the early years, aviation was unregulated but grew during World War I when airplanes took on roles like reconnaissance and bombing. The first airmail flight was in 1918. The Air Commerce Act of 1926 established the first government oversight of aviation in the US. Jet aircraft were introduced in the mid-1900s, highlighting the need for more regulation to prevent collisions as air traffic increased.
