Clyde Edward Pangborn (October 28, 1895 – March 29, 1958) also known as “Upside-Down Pangborn” was an American aviator who performed aerial stunts during the 1920s. Along with his co-pilot, Hugh Herndon, Jr., Pangborn was the first person to fly non-stop across the Pacific Ocean.Once again, you know: you just can’t make this stuff up. (Or should I say, you can’t make this stuff upside-down? Never mind.)
