Stinson 10A

The Stinson 10A is a high wing, single engined airplane. It was developed in the late 1930s and was used by the US military and the US Civil Air Patrol. It was used by the US CAP to spot German U-Boats along the United States' coasts. Once the aircraft's crew spotted a submarine it would radio for a patrol bomber to drop depth charges. After several U-boats escaped during the time it took for the bomber drop its payload, the spotters were soon equipped with small bombs.
