Key American Airliners of the 1930s
Ford 5-AT – Boeing 247 – Douglas DC-3
While war drives rapid technological change competition in business is also a very strong driving force for change. The period between the two world wars in the United States saw the growth of a vibrant and highly competitive air transport industry, spurred on by a growing market and long distances between population centers. This led to a revolution in the design and construction of airliners. There was only ten years between the first flight of the first of the aircraft we are looking at today and the third. The revolution in aero engines was also dramatic with the engines on the first aircraft being only about a quarter the power of the engines of the third aircraft.
