Other mistake: General Butarra holds his pistol to St. John's head asking him where the diamonds are, dry firing it when he doesn't tell him, so the chamber must be empty. He then proceeds to load a magazine into the gun, but never chambers a round, and then proceeds to shoot the radio when it receives a storm alert broadcast. (00:28:40 - 00:29:11)
Ground Zero - S4-E14
Other mistake: When Hawke blows up Yahara's plane, we see that the video feed in the holding cell where Locke, Santini, and Rivers are is actually from a 3rd person perspective and that it continues, but according to previous dialogue (and video up to that point) the camera was installed on the plane, so once Hawke blew the plane up, there should have been no more video feed. (00:40:35)
Continuity mistake: Just as Santini lands his helicopter after his rear rotor was destroyed, Hawke gets into his jeep and drives off. The number plate (licence) is reversed and Hawke's steering wheel is on the right side like British vehicles are. The next shot you see the shot has been flipped the correct way with both plate and steering wheel on the left side. (00:24:14)
Continuity mistake: When Dominic is driving to Airwolf, in the long shot, he has shades. In the closeup, he doesn't.
Airwolf (a.k.a. Shadow of the Hawke) - S1-E1
Continuity mistake: When Hawke lands the helicopter during the film shoot, you see that the person in the left seat is handling the controls of the chopper normally, left hand on the collective, right one on the cyclic. In the next shot, the actor in the police uniform, sitting in the left seat, hides his face behind his arms and does not touch the controls at all.
Continuity mistake: Flight scenes and especially dog fights seem to have no continuity at all. Altitude changes from scene to scene between extreme low-level to altitudes above 10,000 ft. and back. Airwolf's weapon bays are open, then closed, etc.
Chosen answer: Archangel and the Firm provided fuel and armaments. Dom and Hawke would have had to transport them to the lair to refuel and rearm.
