Roy Knabenshue’s July 1905 flight aboard airship Toledo Number One from the Lucas County Fairgrounds on Dorr Street in Toledo, Ohio to the Spitzer Building where he landed on the roof (a distance of 3 miles in 25 minutes) and then returned. For his feat, Knabenshue received $500 from Al Spitzer. This event marked the first time a lighter-than-air vessel landed on a building.
