Civil Air Patrol (CAP) is the civilian auxiliary of the United States Air Force (USAF). It was created by in December 1941, with Maj. Gen. John F. Curry as the first CAP national commander. The organization was originally formed to provide civilian air support to aid the war effort of World War II through border and coastal patrols, military training assistance, courier services and other activities. These efforts were recognized and, after the close of the war, Civil Air Patrol was transferred from the United States Army to the newly formed Air Force. It was incorporated as a non-profit organization of volunteers and declared to be of a benevolent nature, never again to be involved in direct combat activities.
Since that time, Civil Air Patrol has carried out three congressionally mandated objectives: emergency services (including search and rescue operations), aerospace education for youth and the general public, and cadet programs for teenage youth. In addition, it has been tasked with assisting the United States Department of Homeland Security, and also performs non-auxiliary missions for various governmental and private agencies, such as local law enforcement and the American Red Cross.
The general idea of the Civil Air Patrol (CAP) originated with a collective brainstorm of pilots and aviators before the start of World War II. In the later half of the 1930s, the Axis powers became a threat to the United States, its allies and its interests. As the Axis steadily took control of the greater part of Europe and South-East Asia, aviation-minded Americans noticed a trend: in all of the conquered countries and territories, civil aviation was more or less halted in order to reduce the risk of sabotage. Countries that were directly involved in the conflict strictly regulated general aviation, allowing military flights only. American aviators did not wish to see the same fate befall themselves, but realized that if nothing was done to convince the federal government that civil aviation could be of direct and measurable benefit to the imminent war effort, the government would likely severely limit general aviation.
