National Air Transport was a large United States airline;^[1] in 1930 it was bought by Boeing. The Air Mail Act of 1934 prohibited airlines and manufacturers from being under the same corporate umbrella, so Boeing split into three smaller companies, one of which is United Airlines, which included what had been National Air Transport.
