Continuity mistake: The USS Patrick Henry in "JAG" has always used the hull number "74" on the sailors' ballcaps, as well as the scenes of the ship. (CVN-74 in real-life is the USS John C. Stennis). However, in the scene just before the pilots' briefing, the stock footage of the carrier was of a different vessel, hull number 59. In real-life, "59" was the USS Forrestal (CVA-59), the ship that had one of the deadliest shipboard fire on July 29, 1967. The fire killed 132 crewmen, injured 62, with 2 missing & presumed dead. The fire raged for several hours & would have destroyed the carrier, if not for the actions of the heroic crewmen to save her.
Revealing mistake: While at Ft. Leavenworth, the show indicates that Harm is picking up Father O'Rourke from Kansas City International Airport. Having spent many years there, the buildings, etc that were shown are not KCI. Also, L-1011's did not and do not routinely fly in or out of KCI, as one L-1011 was seen flying overhead
