Helicopter pilot Sam finds himself up against a ruthless gang of drug dealers.
Sam's helicopter used throughout the movie. It takes a lot of punishment before being finally brought down by gunfire. Sam manages to land the disabled chopper safely, though. Registration N4EE, Serial 113-0537S.
Used by Zervasco's henchmen throughout the movie. One is Reg. N62345 Serial 2407 (even though Sam claims the numbers have been painted out), the second (not shown) is Reg. N62250 Serial 2334. The red one is accidentally disabled by gunfire from the gray one; the gray one crashes into a cliff.
Chases Sam and Chris at the border. Chris disables it with a flare gun.
Zervasco's helicopter. Reg. N341BB. Sam steals it after his Hughes is shot down by climbing aboard it in mid-flight and throwing Zervasco and his pilot out.
Sam's old biplane. Flown by his old war buddy Frank at the climax, when he and two other biplanes (comprising "Chicken Squadron") come to the rescue of Sam and Chris.
Two of these accompany Frank in the Waco UPF-7 to engage the helicopters of Zervasco's henchmen in midair battle. One is shot down, the other assists Frank in forcing the henchmen's Lama down.
