When the UCAV is first taken for a test run, Lt. Ben Gannon is heard to say "Let the schoolin' begin!" right before the fighters break formation, yet on the screens in the command center showing facial shots of each pilot you can clearly see his mouth is not moving.
Survival training must not have been a high priority for these elite pilots. Breaking radio silence over enemy territory to relay unimportant information and drawing attention to oneself while attempting to evade are just a couple of the errors these aviators make.
When Lt. Gannon dives towards the building "under construction" he says no collateral damage but you clearly see that a part of the building on the left hits the building next door. Plus just before you see a bustling market at the foot of the building.
An elite combatant would not fire a missile in a close-quarters situation, especially when other weapons are available. Anyone with just moderate training would know how to choose the right weapon for the right job.
The soldiers are told that going into North Korean airspace would be an act of war. However, the US is still technically still at war with North Korea. The Korean conflict has never officially ended, and the peace proceedings are violated regularly across the DMZ.
The hi-rise bldg that is blow-up by the bomb is supposed to be in Rangoon Burma. But since scenes of the movie were shot in Thailand and they had a Thai staff, the building was actually CGI-ed in on the west side of the highway leading from downtown Bangkok to the old airport at Don Muang. Watch the cars on the nearby highway. They are driving on the wrong side of the road. Thailand follows the British style of driving on the left. Although they were (and likely because they were) a British colony, Burma followed that style for decades, but a few years ago (in a statement of independence) they flipped the entire roadway system to drive on the right.
The USS Abraham Lincoln is located in the Philippine Sea. The three Talons and the EDI fly westwards, to Myanmar. It is daylight in the Philippine Sea but nighttime in Myanmar. Although it is conceivable that they were flying from dawn westwards to where it was still just before dawn, there were a lot of people and traffic on the street, which would have indicated that it was early evening in Myanmar.
When the Talons are about to get catapulted off the Lincoln early in the movie, one is shown with the yellow chocks around the wheels, and steel chains and hooks still attached holding it down to the deck to prevent movement. This is not the standard configuration for a jet just seconds from being catapulted airborne.
The reported Factual Error that the naval officers incorrectly wear their rank insignia on their collars in the manner of Marine Corps officers is itself incorrect. When wearing the Service Khaki uniform (as shown in this movie), officers wear miniature sized metal grade insignia on the collars of khaki shirts. Source: Navy Uniform Regulations, Chapter 4, 4104.
In the sniper shot fired by the North Korean at Lt Wade, the sound of the gunshot is heard before it seen penetrating her. The gunshot sound would have been heard after the bullet hit it's mark, since the scene is shown from the opposite side of the cliffs from where the shot was fired. Part of a gunshot sound is the sonic boom of a bullet exceeding the speed of the sound.
In the war game scenario at the beginning, the planes are getting heckled by both Anti-Aircraft Artillery and Surface-to-Air Missiles. SAMs are only useful when the planes are flying above 500 feet, however, so they should have been no problem. Likewise AAA does not criss-cross as shown, for fear of destroying each other.
The planes were flying at 15' in altitude over rice paddies and water at very high speeds. The force of the air being compressed under the jet would have made major disturbances in the water - yet nothing happened to the terrain. A few seconds later, they flew over building and ripped the roof tiles off.
Although the aircraft carrier is identified as the USS Abraham Lincoln (CVN-72) early in the movie, and initial action is indeed on the Lincoln, subsequent scenes are on both the USS Nimitz (CVN-68) and the USS Carl Vinson (CVN-70) as indicated by the large "68" and "70" on the flight deck and island structure.
