The National Aviation Day (August 19) is a United States national observation that celebrates the development of aviation. The holiday was established in 1939 by Franklin Delano Roosevelt, who issued a presidential proclamation which designated the anniversary of Orville Wright’s birthday to be National Aviation Day (Mr. Wright, born in 1871, was still alive when the proclamation was first issued, and would live another nine years).
You can read more about it on Wikipedia.
USA Today has a nice historical photo retrospective you can check out.
