As part of a deal with an intelligence agency to look for his missing brother, a renegade pilot goes on missions with an advanced battle helicopter.

Dominic Santini: Why can't we hover like regular helicopter people?
[Opening Narration, to the series]
Narrator: This briefing is from file A56-7W. Classified Top Secret. Subject is, Airwolf. A Mach 1+ attack helicopter with the most advanced weapons system in the air today. It's been hidden somewhere in the Western United States by it's test pilot Stringfellow Hawke. Hawke has promised to return Airwolf only if we can find his brother, St. John, an MIA in Vietnam. We suspect that Archangel, deputy director of the agency that built Airwolf is secretly helping Hawk in return for Hawke flying Airwolf on missions of national concern.
Narrator: Stringfellow Hawk is 34, a brilliant combat pilot. His only friend is Dominic Santini, who's air service is the cover for their government work.
Narrator: With Hawk and Santini working as a team and flying at speeds rivalling the fastest jets, maxed by unmatched firepower, Airwolf is too dangerous to be left in unenlightened hands. Finding it is your first priority.
Michael 'Archangel' Coldsmith Briggs III: I may not be accurate about your location, but I can sure make an educated guess as to your destination. Can I assist?
Stringfellow Hawke: Yeah, you can feed my dog!
Michael 'Archangel' Coldsmith Briggs III: How'd you know I was - Sometimes, Hawke, you amaze even me. Good luck!
Dominic Santini: How come Archangel's "good luck" always sounds like "goodbye?"
Dominic Santini: Amazing! Behind that impeccable white suit beats a heart... of recyclable plastic!
Dominic Santini: Whatever happened to that flyin'-by-the-seat-of-your-pants stuff?
Stringfellow Hawke: Oh, that went out when designers started writin' their names on your behind!
Stringfellow Hawke: [to Nhi Huong, as he figures out the "American name" she plans to give her son] Stringfellow's no name for a kid like that!
Michael 'Archangel' Coldsmith Briggs III: Oh, if you'll excuse me, I think I'll just go stare at the lake.
Dominic Santini: [after they've flown Airwolf into the Upper Atmosphere] Now, would mind telling me why the hell we did that?
Stringfellow Hawke: I just wanted to see if it could be done.
Le Van 'Half-Pint' Hawke: I was so scared for you.
Stringfellow Hawke: They were no match for the Lady.
Michael Archangel: Come 'on Marlene; there must be something out here that desperately needs our attention.
Stringfellow Hawke: You know Half-Pint, How about coming and living with me? I'll make you part of the family, like Caitlan and Dom.
Le Van 'Half-Pint' Hawke: But what if your brother comes back, and it turns out he's not my dad?
Stringfellow Hawke: I'll be your dad.
Dominic Santini: Why not let those people mow their own lawns, huh?
