While talking with Falcon, Harm mentions the "green book" Falcon stole that listed all of the American POWs transferred to Russia after the Vietnam War. But when Harm originally found the book in "Ghost Ship", its cover was yellow.
When Harm is landing the 747, there is a camera shot of Air Force One. (The Presidential seal which is located near the forward doors is briefly visible) There is also a scene immediately afterwards of vehicles following the plane on the runway. These two scenes are from the Harrison Ford movie, Air Force One.
