Other mistake: Recreated newsreel of a trip to Japan by Moe Berg before Pearl Harbor attack shows copyright date of MCMXLIV (1944) in the lower left corner, 3 years after the attack. (00:16:25)
Factual error: USAF is written on the underside of an aircraft's left wing. The U.S. Air Force wasn't created until later. Flight operations were still conducted by the U.S. Army.
Suggested correction: The plane actually has "USAAF" written on the wing: United States Army Air Force.
