Corrected entry: The captain was shot as he sat in his chair and when we left the scene he was still there but when Casey later entered the captain's quarters he was laying on the floor quite far from the chair so even if he slipped down he wouldn't have been in the right position.
Corrected entry: In the scene where Ryback first encounters Jordan after she jumps out of the cake and he takes her into another room, she asks, "what happened to all those guys?" and Ryback starts interrogating her about the helicopter. Jordan starts babbling about "I don't remember anything yada yada yada". Ryback then asks "how many on board?", etc.and she says that she doesn't remember anything. She then asks him if he is some kind of "special forces guy or something" and he says " I'm just a lowly, lowly cook". She then says, "we're all going to die". The problem is that Ryback has not told her about the situation. If she doesn't remember anything and doesn't know anything then why would she say "we're all going to die"?
Corrected entry: An Iowa class battleship 16 inch gun turret requires 77 men to operate. There is no way Ryback and his 6 or 7 guys could operate the turret, let alone fire and reload in the time given.
Corrected entry: As Ryback and his crew prepare to load the 16-inch gun with its first round, you see them being very rough with the 110-pound bags of propellant. This is especially true when the bags are rolled out of the bag hoist and they are allowed to simply "fall out" and slam into the cradle. Anyone working with bags of explosive like that is taking a huge risk.
Corrected entry: Tomahawk cruise missiles on the Iowa class battleships are stored and fired from the armored box launchers mounted on the superstructure. To offload them you would build a crane to swing them over onto the sub. Why build a rail system inside the ship, when the missiles are not inside the ship at all?
Corrected entry: At the start of the movie, Rybeck must make a soup for 1900 crewmembers. Yet in the caboose there's only a few cooking pots (surely not enough to feed 1900 people). Also, Rybeck is slicing a handful of carrots with a simple knife, but you'd expect he'd need several pounds of vegetables and an electric blender to cut them.
Corrected entry: The bad guys construct 'rails' to move the missiles out of the ship, but even before construction, the yellow/black rails are clearly visible, when the captive sailors are being ushered into the holding cell.
Corrected entry: After taking control of the ship, the navy sends an F-18 to the Missouri "to look for the helicopter" as Stranex's man puts it. Let's see. The Missouri is returning to the mainland. It's still carrying its nuclear arsenal and the navy is worried because the helicopter that brought the party guys is missing? Someone's priorities are misplaced.
Corrected entry: Seagal puts some stuff in the microwave that should explode when being heated. When the bad guys are in the kitchen, they hear the microwave beep, then the thing explodes. It's highly unlikely that a homemade bomb will explode at exactly the set time, down to the second, which is over 15 minutes.
Corrected entry: The terrorists who wear IFBs, wear them incorrectly. They have them clipped on the front of their shirts, and then put in the ear. The correct way is to have the cable clipped onto the back of the shirt, and then cord goes over the ear, and into it, making sure the cords do not get in their way.
Corrected entry: In the scene where they begin attempting to transfer the missiles, it shows the submarine tied up next to the Iowa, both ships dead in the water. This is basically impossible, as ocean currents would eventually smash the two ships together, probably causing catastrophic damage. When the U.S. Navy does replenishment at sea, the ships are always moving out of necessity.
