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.
Continuity mistake: When Tom Boone reflects on Hammer being shot down, his helmet reads, "CAG"; which didn't occur for many years. (Stock footage was used from "Defensive Action")
In Thin Air - S8-E5
Continuity mistake: After Rabb flies as RIO near the end of the movie, they land in a F-14 with the number 114, however when they get out of the aircraft the number is 242.
Need to Know - S8-E7
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.
Deliberate mistake: During the civilian sheriff's pursuit of the Navy car, the sheriff is occasionally visible in the passenger seat of his patrol car instead of the driver's seat.
Continuity mistake: The hull number on the flight deck "74" didn't match the hull number on the sailors caps. "74" is the hull number of the Nimitz class carrier USS John C. Stennis.
In Thin Air - S8-E5
Continuity mistake: When Harm goes up with Lt. Albrecht as his RIO, they are shown flying 4 different aircraft - Tomcats 103, 104, 114, 242. This is what happens when stock footage is used.
Factual error: The scene outside the gate of the Naval Amphibious Base - Little Creek was NOT the same as the actual gate. Little Creek does not have palm trees adjoining it. The base itself is located at Norfolk, VA.
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.
Second Acts - S8-E19
Continuity mistake: When Admiral Chegwidden is at the SECNAV's office, he raises a glass of scotch up to his mouth. In the next shot, the hand holding the glass is down in his lap. (00:26:45)
Critical Condition (3) - S8-E1
Continuity mistake: When Mac is trying to decide which book to pack, she is looking at both front covers. When the shot changes, she is instantly looking at the back cover of the book in her left hand. (00:04:35)
Answer: Officially, the individual has been ordered to attend, failing to could be interpreted as either, Failure to follow orders, dereliction of duty, going AWOL, or even desertion. It would depend on the underlying reason as to why the person doesn't appear.
