CURTISS' HYDRO-AIRCRAFT PATENT.
1. Printed document, 1 p, 12½ x 8 inches, executed February 15, 1917, accomplished in typescript and manuscript, being an assignment by Glenn Curtiss of "the improvements in Hydro-aircraft" and the associated patents to the Curtiss Aeroplane and Motor Corporation of New York, SIGNED by CURTISS, notarized, and docketed with US Patent Office seal.
2. 3 black and white photographs, 5 x 6½ inches, being two images of Curtiss' NC-4 flying boat and one close-up of an NC-4 engine.
In 1917, the US Navy commissioned Curtiss to design a long-range flying boat to hold a crew of five. In May, 1919, the resulting NC-4 became the first aircraft of any kind to fly across the Atlantic Ocean (albeit with a stop at the Azores). By flying from Massachusetts via Halifax to Lisbon, the NC-4 also flew from mainland-to-mainland of North America and Europe. The NC-4 is on loan from the Smithsonian to the National Museum of Naval Aviation in Pensacola, FL.
