Statistics on the comforts of American homes in 1927 come principally from the March and July issues of Scientific American. Other details come from American Culture in the 1920s by Susan Currell. For the state of American highways at the time, see The Lincoln Highway by Drake Hokanson. The situation at Roosevelt Field in May 1927 is well covered in “How Not to Fly the Atlantic,” American Heritage, April 1971, and in The Big Jump by Richard Bak and The Flight of the Century by Thomas Kessner.
