Carter is told told to lower his landing gear, but the gear is clearly down when the plane is seen from behind.
When Chick takes off in a silver early-model B-17 to prove bombing accuracy to some visitor big-wigs, he takes off in a plane with the number 51 on it's nose. In a subsequent shot, the number is 62, but the image in that brief shot is also reversed.
Near the end of the movie Capt. Buck Scott's (Randolph Scott) plane is shot down. As the plane is going down, the bombardier, Joe Connors (Robert Ryan), must destroy the bomb sight. In one scene, he pulls a .45 semi-auto (M1911), cocks it, and fires one shot. In a subsequent scene, he fires multiple shots but he is now shown firing a revolver. This most likely is because blanks fired from a semi-automatic generally do not have enough energy to "cycle" the weapon in order to chamber another round (thus, one shot and done). A revolver firing blanks has no such limitation.The raid over Tokyo did not use the Norden bomb sight a simple directional linear sight was used. The high risk mission meant some airships would be shot down or captured in China resulting in the fear the Norden sight being captured.
When the B-17s are being armed (bombed up) for the mission to Nagoya, there is a brief glimpse of a Consolidated B-24 Liberator being loaded. There was no previous mention of B-24s being on this mission.
The Douglas B18's, Beechcraft AT11's and B17 aircraft all sport national markings found from May 1942 until June 1943, yet a considerable part of this film takes place before Pearl Harbor.
Near the end Randolph Scott drives a Japanese truck. The steering wheel should be on the right side of the truck since in Japan they drive on the left.
Near the beginning of the movie Capt Buck Oliver, demonstrating dive bomber tactics, uses a Navy SB2U Vought Vindicator; an Army Air Corps pilot would have used an Army plane such as the Douglas A-24 (the Army version of the Navy SBD Dauntless), which in use before Pearl Harbor.
Master Sergeant Archie Dixon is a senior non-commissioned officer before and after Pearl Harbor. He would not be a B-17 tail gunner, which was usually a lower-grade enlisted man. Mostly likely Dixon would have been a crew chief or flight engineer and back at the base, not in an airplane.
Boeing B-17 Flying Fortresses never bombed Nogoya or any other part of Japan. They didn't have the range to reach Japan from the nearest Allied-held bases in the Marianas, Okinawa, or China. In fact, the B-17's range was such that most of them were withdrawn from the Pacific Theater and employed in Europe by 1944.
When the bomber with the stuck flare is shown flying through the air, the flare's parachute is shown caught on the tail landing gear and flapping wildly in the air, but the flare itself is in a fixed position near the tail and not moving at all, showing that it isn't attached to the parachute at all.
Safety wire can clearly be seen tied to the crewman after he deals with the stuck flare.
Wires are clearly visible on Buck's plane and on most of the aircraft in the big bombing raid.
When Oliver's B-17 is going down in flames, for an instant, the guide cables for the model can be seen.
The "secret island" which is used as the base for the attack on Japan near the end of the movie seems to be awfully flat, large, and arid for an island in the central Pacific.
The pilot would never have bailed out of his plane without trying every procedure to save it, including the shut-down procedure that eventually freed the stuck controls. Nor would a commanding officer have ordered everyone to bail out of said aircraft before all possible procedures had been tried to save it.
When Major Davis first arrives at Hughes Field, as he is walking up to the sign, a clear shadow of the boom microphone is visible on the ground in front of him.
When Oliver is captured, one of the Japanese tears open his flight jacket to find his rank when it is plainly visible on the shoulder epaulets of his flight jacket.
