National Aviation Day
August 19, Monday
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).
