 Though the regulatory actions of the Civil Aeronautics Board ultimately extinguished the burgeoning non-scheduled industry, the idea of cheap, efficient air transport endured and by the passage of the 1978 Airline Deregulation Act nearly all civil airlines had transitioned to an aircoach model.The first non-scheduled airlines arose from the industrial and human fallout of the Second World War.The wartime United States aviation industry had, upon the orders of President Franklin Delano Roosevelt, escalated the production of aircraft from a few thousand a year to more than 4,000 each month, and the training centers of the U.S. Army Air Force produced the pilots to fly them.
