The Curator’s Choice 55

Key American Airliners of the 1930s

While war drives rapid technological change competition in business is also a very strong driving force for change.

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.
