Goofs

 * Molly is making adjustments to the wedding dress modeled by Tinker. When he turns around "U.S. Air Force" appears on the back (apparently because the dress was made from a parachute). The U.S. Air Force did not become a separate military organization until 1947. During WWII it was part of the U.S. Army and called the "Army Air Forces".
