The background for the opening titles is a map of the Panama Canal. The orientation of the map and the compass is correct, but the labeling of the map is incorrect. In fact, the Atlantic end of the canal and the city of Colon are at the upper left (Northwest), and the Pacific end of the canal and Panama City are at the lower right (Southeast). The map is correctly labeled behind the closing credits.

As Leland is entering through the glass door to the NYK Line Agent's Office (to buy a steamer ticket), there is a nearly square flag painted on the door. The flag shown is a red circle with 10 rays extending from it to the edges in a sunburst pattern. This flag never existed. The appropriate ensign/flag for a non-military maritime organization such as Steamship Company in the immediate prewar period would have been the meatball* on a field of white, or the same as the nation's present flag. The nearest thing to what is shown is actually one with only eight rays flown by the "Japanese Ground Defense Force". It was the sunburst flag with sixteen rays that was widely used by the Japanese military (Army and Navy) throughout WWII - generally up to 1945.

((*) The red circle used by the Japanese for both flags and aircraft roundels during this period was, in those days, uniformly referred to by all of the Allies (military and civilian alike) as "The Meatball".)

In an early scene, we see a court martial proceeding and afterwards Army Captain Rick Leland says he has been dishonorably discharged. In the US military, that status can only be applied to enlisted men. Commissioned officers convicted in a court martial may be dismissed, but they are not dishonorably discharged.

On the patrol flight schedule Lorenz examines, the times are show as AM/PM. In actuality, the times would be in military 24-hour format.

When Alberta's back is badly sunburned, she writhes in pain when Rick lightly touches it but doesn't even wince when he rubs oil on it. She should have shown at least some discomfort.

The magazine that Rick buys for Alberta when they first arrive in New York is the Aug. 16, 1941 issue of "The New Yorker" (the movie is set in December, 1941).

While Humphrey Bogart's character is being read the findings and recommendations of the court, he pivots to leave even before the judge finishes speaking. Not very military, unless the director meant it to be a character development showing disrespect for the institution.
