Continuity mistake: When they try to land the C130 on the aircraft carrier, the co-pilot says that they don't have the right landing gear down, so she goes to the back to instruct one of the passengers how to lower the gear manually. The problem is that they lower the left gear, which was already down.
Factual error: Season 9 Episode 5, "Touchdown": When they approach the aircraft carrier, the copilot says that the number two engine is flaming out. This means there is no more fuel to run that engine. That supposedly also means that there is not enough fuel for a fire alarm lighting up in the cockpit, which is what happens in the show. (Verified by a USMC Staff Sergeant who flew 8 years on a C130).
Factual error: During the approach on the aircraft carrier, they had to put out the gear manually. The copilot shouts that she has three greens (meaning that all gears are down and locked), then she puts the gear lever up. If that is done, the gear would raise again or be in an unsafe position for the landing.
Revealing mistake: When the plane approaches the aircraft carrier, they have to dump fuel, and the fuel comes out through the back. However it should be coming out on the wing tips. So they had a tank of water or something similar that they sprayed out through the back. (Confirmed by a Staff Seargent with the USMC who flew 8 years on a C130.)
Factual error: When they have to jettison fuel during their final approach to the aircraft carrier, Rabb tells his co-pilot to dump 200 pounds of fuel. That is about 30 Gallons (about two normal car tanks). But there is way too much fuel being dumped to be only 30 gallons.
Revealing mistake: The cockpit of the C130 is not correctly rebuilt. The pilots are sitting too close to each other. (Verified by a former C130 pilot with the USMC.)
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.
