The view of the Trans World Airlines (TWA) hangar containing airplanes in an unnamed airport in Boulder City, Nevada. One of America's oldest International Air Carriers (INAC) that was popular during the twentieth century, the Trans World Airlines was aided by aviator Charles Lindbergh in mapping out the company's early air routes, and so in the 1930s Trans World Airlines was also known as "The Lindbergh Line." Transcribed across the top of the building: "Fly TWA, The Lindbergh Line. Chicago, New York. Los Angeles, San Francisco."
