Abrams P-1 Explorer
The Abrams P-1 Explorer was a United States purpose-designed aerial photography and survey aircraft that first flew in November 1937. It was designed by aerial survey pioneer Talbert Abrams to best suit his needs for a stable aircraft with excellent visibility for this kind of work. Abrams was an early aerial photographer, in World War I. He used a Curtiss Jenny post-war, forming ABC airlines. In 1923 Abrams founded Abrams Aerial Survey Company, and in 1937 Abrams Aircraft Corporation to build the specialized P-1 aircraft.
==Conception==
The standard single, front-engined airplane of this era created many problems for good scientific photography. They were created to be very nimble in the air and rather than stable photographic platforms. Their engines leaked oil which would flow under the aircraft and get on the camera lens. The engines were noisy and the noise flowed back into the cockpit making conversation difficult.
The designer of the Abrams P-1 Explorer conceived a plane with a wide wing span to be more stable, and with a rear engine to keep the camera clear. He wanted a delta type wing so side vision was possible. He hired engineers Kenneth Ronan and Andrew Edward Kunzl in Marshall, Michigan who drew plans and began construction in the old Page Brothers Buggy Company factory.
Ronan and Kunzl operated an aeronautical repair station at the Marshall airfield. Ronan was in the first graduating class of aeronautical engineering from the University of Michigan. Careful planning and ten months of construction produced an airplane capable of more efficient and economical aerial photography.
