Ryan S-C
The Ryan S-C (Sports-Coupe) (or Sport Cabin) was an American three-seat cabin monoplane designed and built by the Ryan Aeronautical Company. At least one was impressed into service with the United States Army Air Forces as the L-10. Development. The Ryan S-C was a low-wing cantilever monoplane with a fixed tailwheel landing gear, designed to be an up-market version of the Ryan S-T trainer. The prototype first flew in 1937, and had a nose-mounted 150 hp (112 kW) Menasco inline piston engine. Production aircraft were fitted with a 145  hp (108 kW) Warner Super Scarab radial engine. With the company's involvement in producing trainer aircraft for the United States military, the S-C was not seriously marketed, and only 11 complete SCs (s/n 202 through 212) were built, all delivered in 1938; two more were later assembled from parts (s/n 213 in 1941 and s/n 214 in 1959). At least one example – probably as many as five, s/n 202, 203, 207, 211 and 212 – were impressed into service with the Civil Air Patrol, auxiliary of the United States Army Air Forces for anti-submarine  patrol and warfare duties on the East coast of the US, and was designated the L-10. At the start of the 21st Century, four examples were still airworthy in the United States.
