First flight of the prototype (XR-6) of the Sikorsky R-6 Type series

Friday, October 15, 1943



Some sources refer to the aircraft as the R-6 but this is believed to be the generic military designation for the Type (also knows by the company designation S-49). The XR-6 designation correctly refers to the experimental ('X') nature of the prototype.
