Continuity mistake: When Rabb lands at Norfolk the number of the chopper is 426, there he meets Commander Turner who says that he takes the same chopper as transport to the submarine. The Sea Knight is the last transport to leave the base before lock-down. When the same chopper approaches the USS Crawford it suddenly has the number 62.
Continuity mistake: As Harm & Mac are taking off, Mac reminds Harm how much she hates flying, especially since the last time they went up, they crashed & she was stabbed in the leg ("Full Engagement"). In that episode though, Mac is shot, not stabbed. The comment is also in error as the last time the two went flying was when they flew a MIG-29 & ejected after being fired upon in "To Russia With Love".
Continuity mistake: The scenes that appeared on the television that the Sheriff was watching at the beginning was from the 1970's movie, "Smokey & The Bandit". Several of the clips were out of order, not to mention jumping from the beginning of the movie, then close to the end.
Factual error: Those that have a technical background may have noticed at the end, when the sub was destroyed due to being crushed from the water pressure, it was shown as having EXPLODED, instead of IMPLODING. This was due to the cost of setting up a shot, when stock footage was already available.
Continuity mistake: When Ducky is performing the autopsy on Lt. Singer, Vivian dabs a vapor neutralizer under her nose, screws the top back on, and puts it in her pocket. In the following wide shot, she screws the lid on again and puts it in her pocket a second time. (00:15:35)
Continuity mistake: When the armored car with the money arrives, the scene starts with the time 10:32 typed on the screen. It is full daylight and shadows are short, so this is consistent with the printed time. When the next armored car arrives empty, it is supposed to be one hour later, but it is pitch dark. The characters say that the first truck came at 17:00 hours (which would be 5:00 p.m.) and the truck before them was scheduled for 18:00 hours.
