In 1939, President Franklin Delano Roosevelt proclaimed August 19 – birthday of first pilot Orville Wright – as America’s first National Aviation Day celebrating the development of aviation.
This Sunday marks the 73rd observance of National Aviation Day, so how does an aviator mark the occasion? Get out and fly! EAA encourages its aviator members to inspire a child by taking him or her on a Young Eagles flight, provide an Eagle Flight to an adult friend or acquaintance who has an interest in becoming a pilot, or simply go out to your local airport and make a few circuits around the pattern.
Happy National Aviation Day, everyone!
