Continuity mistake: When Lasky heads toward the conning tower, an A-7 Corsair is shown at left (and the helicopter nose has a number "3" on it). As he is led inside the tower, the camera pans up, and now the Corsair is gone, replaced by an E-2 Hawkeye (and the number "3" on the heli is gone, too). (00:06:45)johnrosa
Continuity mistake: There are two F-14s that deal with the yacht and the two Zeros. They are respectively numbered 202 and 203 prominently on both sides of their forward fuselages. But when one fires a missile to down the second Zero, suddenly it is number 200, a jet that hasn't been launched. (00:50:25)johnrosa
Plot hole: While still unsure where and when they are, the Nimitz has two F-14 Tomcats aloft, investigating a pair of low-altitude radar contacts. They determine the planes are WWII-vintage Japanese Zeros in full military livery. The Tomcats are told to shadow the Zeros without engaging them. Then, the Captain, the XO, the CAG and Lasky all go to a formal dining room and sit down to tea. In this scene, they talk about many other 1941-era things that are happening, but nobody mentions the Zeros. That fact, and that they left their Tomcats where they did, suggests this scene was meant to be in an earlier part of the film (when things seemed odd, but no imminent threat existed) and got moved here, creating a plot hole that the USS Nimitz could slide through sideways. US Navy nuclear carrier command staff wouldn't simply go have tea under the current conditions. (00:40:30)johnrosa
Continuity mistake: During the dogfight with the Japanese Zeroes, the ordnance hung on the two F-14s' weapon stations keep changing. For the weapons to change, the airplanes would have had to land and re-arm about four times during the two-minute dogfight.
Factual error: When Captain Yelland is shown the reconnaissance photo taken over Pearl Harbor by his own plane, it is identical to the historic photo from Commander Faraday's files. If you look at the picture, you can see 2 torpedo wakes heading towards the ship in the center of the photo. This is confirmed by the Discovery Channel's "Death of the Arizona" program. The photo was taken just as the attack began, and at this time in the movie, the attack was still a day ahead.
Factual error: Pearl Harbor is said to be 280 miles away from the USS Nimitz. An F8 Crusader on a recon mission to the harbor reports unusual shipping traffic, and that he will make another pass for a close-up series of photos. The CAG then immediately states the F8's ETA (estimated time of arrival) back to Nimitz is 12 minutes. At its maximum speed of 1,225mph, it will need to skip the second pass entirely to have any hope of returning in 12 minutes. (00:23:55 - 00:27:25)johnrosa
Factual error: Aboard the Navy helicopter Senator Chapman slugs a Navy seaman in the head, knocking the sailor out cold on the first punch. But the sailor was wearing a helmet, hard on the outside and padded on the inside. It's not all that easy for an average person to knock someone out bare-handed; it's probably nearly impossible to do so through a helmet that's designed precisely to protect the head from hard impacts.
Other mistake: Cpt. Yelland and civilian observer Lasky are trying hard not to mess up with the timeline. Changing little things in the past could have tremendous results in the present/future. However they already disrupted the natural timeline by shooting down 2 Japanese Zeros, killing both pilots, leaving behind CAG Owens in 1941 and rescueing secretary Laurel Scott who would've been killed for sure by the two previously shot down Mitsubishi Zeros.Goekhan
Continuity mistake: The yacht has been blown up by the Japanese Zeros. A helicopter is sent out from the USS Nimitz to pick up the survivors. When Charlie (the dog) is being lifted into the helicopter (carried by Commander Owens) he is obviously soaking wet. When Commander Owens hands Charlie over to Laurel, Charlie is suddenly bone dry.

Continuity mistake: Weapons come and go in the battle scene between the two F-14's and two Zero's. One of the F-14, supposedly 203 but marked 200, fires a sidewinder from its left side and the hard point is completely empty, it was fully loaded at the start of the combat and had only fired 1 missile. The AIM-7 Sparrow which was supposed to be there is gone, also all the AIM-54 Phoenixes that were seen earlier are gone as well. In the next shot showing 202 and 203 flying next to each other, both planes are fully loaded again, no missiles fired at all.
Continuity mistake: At the beginning of the movie, Cmdr Owens lands an F-14, number 200. Immediately after landing while the plane is raising its tail hook, we see the number 203 on the right wing flap, then after a short cutaway, we see the plane again taxi to the right but now the right wing flap's number is back to 200.

Continuity mistake: In the opening scene, as Lasky prepares to board the helicopter, a blue GM station wagon is seen in the background, parked in front of a yellow Pinto. Watch carefully, as the car is partially hidden by the limo. By the last shot, the station wagon turns into a Ford sedan. (00:02:20 - 00:03:25)
