Factual error: The film's plot violates the third of the Ten Immutable Laws of Security by Scott Culp. The premise of the law is: When one has physical access to a computer system, given enough time, he can take over the system. In the film, the reverse happens: Dane takes over an ATAC site remotely while people inside (who have complete physical access) cannot do anything to wrest the control back. In the real world, it is usually possible to simply cut the connection cable or antenna and take control back. (Even Windows XP and later have such simple lockdown provisions as part of Windows Firewall.) After the lockdown, the passcodes can be changed and other measures taken.

Factual error: The main premise of the film is ATAC's loss of control over their orbital weapon and their attempt to prevent it from doing damage. According to ATAC, they needed to know where the weaponized satellite is, so that they can lock onto it and send it a self-destruct order via radio waves. This isn't how the real world works: Radio waves emit in all directions from its transmitting source. The location of the satellite need not to be known; only it must be within the reach of the ATAC's signal.

Continuity mistake: General Iroh attacks a squadron of five combat planes belonging to Amon. He downs two immediately. One fires back and ascends. At this time, the face of the pilot is shown. The other two descend. Iroh follows and destroys them. At this time, the ascending plane drops bombs. Again the face of the pilot is shown, but the pilot is a completely different one. The first time, he has a taller face, thick eyebrows, a pair of round and brown-tinted goggles and no mustache. The second time, the face is rounder, the eyebrows are thinner, the goggles are rectangular and pale, and there is a mustache.

Plot hole: Guards at a security checkpoint attack Varrick and Bolin, because a wanted poster identifies them as fugitive traitors. The problem is that poster cannot have been there. Varrick and Bolin escape in the previous episode (Battle of Zaofu) but are captured minutes afterwards. (So, no posters needed.) The next day, they escape again by blowing up their imprisoning train car. Their captor, Bataar, thinks they are dead. Indeed, Varrick intended to die. Later, Bataar is actually shown reporting them dead. One might argue that the poster wasn't a wanted poster, but one that warned people about the empire making an example of the traitors.This argument is too flawed: The empire had many examples already, some very high-profile. And a propaganda poster must be placed in plain sight, not in a security booth corner especially designated to let security guards compare the passing individuals.

Factual error: While fighting Scorponok in Qatar, the special ops team requests a gunship to attack with 105 shells. The gunships confirms but no 105mm shot is fired. The gunships fires three rapidly firing cannons within 17 seconds. 105mm shells cause a massive explosion upon impact, and aren't reloaded that rapidly because of their weight.
