Corrected entry: Throughout this movie these guys were shooting off more rounds than Rambo. In an enclosed sub, wouldn't they be concerned with getting hit by their own bullets once they ricochet off the walls?
Corrected entry: Throughout the movie, when the sub is submerged, it show the submarine about 10 meters down, not 100, or 200 as the characters stated.
Corrected entry: For the raid on U-571, Tyler chooses to dress as a German officer, thus making himself the most likely one of the boarding party to be addressed by the German crew, even though he speaks no German (which ultimately gave the deception away early). This tactical error is inexplicable, given that there were two fluent German speakers among the Americans.
Corrected entry: Why does the German re-supply U-boat open fire on the disguised American sub when they are docked with U-571? The American Sub is disguised well enough to pass a visual inspection, and you'd think the Kriegsmarine sailors would be pleased to see some fellow Germans at sea. They certainly wouldn't simply open fire with torpedoes because they didn't recognise the other U-boat.
Corrected entry: After having his language skills tested, the German speaking Seaman Wentz implores Tyler not to reveal his half-German background to the other men, even though he openly uses a German surname.
Corrected entry: The German commander is depicted eating a piece of fruit just prior to the depth charge attack against the U-571. No German commander would have done this. Food was strictly rationed and accounted for on the boat for various reasons - not the least of which was making sure there was enough to last for the duration of the patrol. If men were allowed to grab food and eat it as it suited them there would be no way to control its consumption. No commander would have set such a dangerous precedent by such wanton consumption.Badbird
Corrected entry: Anybody with any mechanical knowledge seems to have been killed in the fire in the engine room, on a sub on patrol there would have been at least two watches, one working, one resting and both watches would not have been in the engine room at once.
Corrected entry: In the scene on the dock where the mess steward sees the lieutenant struggling to light a cigarette, he comes over and offers his lighter. The officer was actually facing away from the sailor, so how could the mess man even know the lieutenant could not light the cigarette?
Corrected entry: The sailors - rightly so - become very frightened when the long range plane spots them. However no sub captain in his right mind would stay on the surface if he heard the sound of an aircraft - it was one of the lookout's primary tasks: alert the captain if they heard propellers, and prepare to dive.
Corrected entry: Enlisted submariners of that time period wore silver dolphins on their dress white uniforms (like the officers wore their gold ones in the movie) and not black embroidered dolphins on their sleeves.
Corrected entry: Once the survivors are in the U-boat the black character mans the controls. He's the cook, how does he now how to operate the controls?
Corrected entry: When the German electrician is tapping that Morse code message, how can the guy who says what it is (who doesn't speak German), understand what he is saying. The message should be "Ich bin U-571. Zerstören Sie mich," since he can't speak any English. (He didn't answer the questions because of that.)
Corrected entry: When the American Navy is called to their assignment, the welders working on the submarine are welding without safety goggles. I would think that in the Navy they would teach basic safety precautions.
Corrected entry: After the American crew takes control of the U-571, it is approached by a German destroyer. The Americans decide to destroy the radio on the German ship with their deck gun. The gun was completely exposed to the destroyer; there is no way to hide anywhere or to work it in secret. How did they manage to get several men out of the submarine to unlock and prepare the gun for firing, load the shell, aim the gun and fire at the destroyer to destroy their radio, completely unnoticed and unmolested by the Germans? This wasn't a task that could be done in a matter of seconds; a minute or two would be needed for the best of crews, let alone for a group of people who'd probably just seen that sort of gun for the first time. The German officers are even shown watching the sub intensely at the start.
