As you view the two sides of the fuselage at about the mid-point between the wing and the tail you will notice a triangular symbol. This symbol represents the Civilian Air Patrol (CAP).
The reason this symbol appears on our museum Stinson is because a number of these aircraft were used to patrol the coastal waters of the eastern seaboard and the Gulf costal area of the United States during the time period of March 1942 to August 1943.
German submarines began attacking shipping off our coastal waters early in 1942. As shipping losses increased, our government authorized the CAP to patrol these areas out of 21 bases along our coast. The CAP flew 86,865 missions for a total of 244,600 flight hours. At first each mission consisted of a pilot and a radio operator/observer with no armament on the aircraft. When a hostile submarine
was spotted the crew would radio the activity to their base whereupon either an army or navy aircraft would be dispatched to encounter the submarine. The patrols also conducted search and rescue missions for survivors of allied merchant ships that had been torpedoed by the Nazi submarines. During the eighteen months of operation the CAP patrols spotted 173 U-boats, located 363 survivors of sunken ships, and reported 91 ships that were in distress.
