[1] Although only one was produced, the Dayton-Wright OW.1 marks the first working example of a civilian single-engine four passenger light cabin aircraft in the US.

Following up on a wartime contract to build the British DH.4 under license, the Dayton-Wright Company looked at development of the type for civil use.

Although based on the DH-4, it had lighter-weight wings, revised landing gear, and a shortened, smaller tail unit.

[1] The OW.1 set an altitude record of 19,710 ft (6,010 m) on 22 May 1921, flown by Dayton-Wright test pilot Bernard L. Whelan, and accompanied by three mechanics as passengers.

The Aerial Coupe reached the record altitude after a 2 hr, 31 min flight over USAAC Test Center at McCook Field in Dayton, Ohio.
