Carillon Park founder Col. Deeds approached his friend Orville Wright about displaying a replica of the 1903 Flyer, but Orville suggested restoring their third airplane instead. This building houses the original 1905 Wright Flyer III, the world's first practical airplane and a National Historic Landmark. Orville considered it the most important aircraft that he and his brother built, and with it they truly taught themselves how to fly. On October 5, 1905, Wilbur stayed aloft over Huffman Prairie northeast of Dayton for over 39 minutes, longer than the combined total of all 109 of their previous flights. Orville Wright suggested the building's interior pit design, which allows visitors to view the aircraft up close and from above. The building was built in 1949 in Carillon Historical Park.
