The Curtiss Twin JN (retrospectively called the Model 1B and also known as the JN-5) was an Experimental aircraft built by Curtiss Aeroplane and Motor Company for the United States Army Air Service. It was a biplane designed for observation missions.Based on the successful Curtiss JN-4 the Twin JN used the same wing structure but the wingspan was extended by enlarging the center section. Lateral control was achieved with the tail of a Curtiss R-4.
