Other: I was so bugged by protocol errors in early episodes that I stopped watching. For example, there were at least 2 episodes where Navy or Marine officers in utility uniforms were wearing Army brass on their collars. In one episode, "Harm" is walking with his female partner through a garage. He returns the salute of an enlisted man who walks by, but she doesn't. In any event, the garage was indoors, where Naval Service protocol says you don't salute.

Continuity: When Rabb & Kate arrive on the Seahawk, they are not wearing the proper life-vests, etc.

Factual error: NASA's Vehicle Assembly Building is located at the Kennedy Space Center in Florida - not Vandenberg AFB, CA

Continuity: The death of the astronaut occurring while practicing the escape in the bucket would never happen in real life. That is because when NASA conducts them in real life before a shuttle launch, the crew practices everything up to entering the bucket. NASA does not want to run the risk of their astronauts being injured during a simple practice.

Factual error: When LCMR Rabb and Lt. Pike get off the chopper on the USS Daniel Boone, they are wearing uniforms with no flight suits on. It is Navy regulation that you have on a full flight suit while in a chopper and not going into combat

Continuity: The hull number on the ballcaps of the sailors on the USS Daniel Boone doesn't match the hull number of the ship used to portray it. The hull number on the caps, DDG-72, is currently assigned to the Arleigh Burke-class Destroyer, USS Mahan.
