Ohio joined the Union on March 1, 1803, becoming the 17th state. The Buckeye State quarter's reverse design honors the state's contribution to the history of aviation, depicting an early aircraft and an astronaut, superimposed as a group on the outline of the state. The design also includes the inscription "Birthplace of Aviation Pioneers." The claim of this inscription is well justified — the history–making astronauts Neil Armstrong and John Glenn were both born in Ohio, as was Orville Wright, one of the inventors of the airplane. Ohio was also the site of the development and testing of the Wright brothers' 1905 Flyer.
The obverse (heads) design features the familiar image of George Washington by John Flanagan, used on the quarter since 1932.
The reverse (tails) design features features an early aircraft and an astronaut superimposed as a group on the outline of the state, and stars.
