According to 36 U.S.C. 118, August 19 is designated as National Aviation Day. First recognized in 1939 by Franklin D. Roosevelt on the anniversary of Orville Wright’s birthday, it was codified in Title 36 with other days of patriotic and national observance. You can see resources about Aviation Law on the library’s Aviation Law Research Guide.
