Airwolf (a.k.a. Shadow of the Hawke) - S1-E1
Continuity mistake: When Stringfellow and Dominic first board Airwolf at the Libyan base, String gets in on Airwolf's right side, and pilots from there. When they land to rescue Gabrielle in the desert, he is in the left hand seat as the chopper lands and gets out of the left hand side.
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.
