A devastated Pete is blamed for overreacting to the incident, and he is forced to turn in his badge.Pete believes that the assault may have been an elaborate prison break meant to free Leedy. But the force refuses to listen saying that the chances of sneaking a parachute through airport security and parachuting at 30,000 are impossible. Renegade skydiver and former DEA agent Ty Moncrief (Gary Busey) is the mastermind behind the attack, which culminated in the first-ever parachute jump from a commercial jet at 30,000 feet. Ty plans to use Leedy to hack into the DEA mainframe computer in Washington DC so Ty can auction off the names of undercover agents to drug cartels worldwide.Ty has scheduled this to be accomplished during an Independence Day parachute exhibition and fireworks display, which is the one day every year when security is loosened around the airspace above Washington DC. Because skydiving played a part in the airplane hijacking, Pete finds his way to Jessie Crossman (Yancy Butler), a world-class skydiver and ex-con, whose ex-husband Jagger, unknown to all, is part of Ty's crew. Jessie agrees to train Pete how to skydive, if he will sponsor her team for the parachute exhibition.When Jessie's parachuting friend Selkirk (Corin Nemec) is severely injured after using a faulty parachute that Ty had intended for Jessie to use, Pete is appointed to take Selkirk's place. When Jagger is found dead, tangled in some high-voltage power lines, it is obvious that his death was a murder engineered by Ty, and with Pete's help, Jessie now is seeking revenge on Ty, when Pete discovers Ty's plan to...

With him is his teenage daughter from his first marriage, Marti, his second wife Carol, and Marti's half brother Andy. On their way to the base, they stop at a gas station. In the restroom, Marti is threatened by an MP member with a knife. When he notices her fear, he lets go of her, satisfied that she shows an emotional response. Before she leaves the room, he warns her, "they get you when you sleep". Steve and his family move into their new home on the base, and Marti makes friends with the base commander's daughter Jenn. On his first day in day care, Andy runs away because he is recognized as an outsider among the other somehow conformist children. He is picked up and brought home by helicopter pilot Tim. Marti and Tim quickly feel attracted to each other. Meanwhile, while examining soil samples, Steve is approached by medical officer Major Collins, who asks him about psychological effects, particularly narcophobia (the fear of sleep), and their possible relation to toxication of the environment. Steve believes that a physiological reaction would be more likely. In the evening, Marti and Jenn go to the bar attended by the station's military personnel, where they meet not only Tim but also the MP who threatened Marti at the gas station. He denies that they ever met before. That night, a group of soldiers can be seen picking giant pods from the river running by the base. When Andy wakes up and enters his mother's room, Carol crumbles to dust, while a soulless double emerges from the closet. Nobody believes Andy's story that his real mother is dead and the person pretending to be Carol is only an impostor. The following night, Marti and her father are nearly "taken over" too by duplicates emerging from the giant pods. Carol attempts to convince Steve that the takeover is a good thing, claiming that it ends confusion and...???
output answer: What does Carol do to alert the other "pod people"?

Please answer this: Generate a question that has the following answer: Cosmo Brown for the following movie plot: Don Lockwood (Gene Kelly) is a popular silent film star with humble roots as a singer, dancer and stunt man. Don barely tolerates his vapid, shallow leading lady, Lina Lamont (Jean Hagen), who has convinced herself that the fake romance their studio concocted and publicized is real.One day, to escape from overenthusiastic fans, Don jumps into a passing car driven by Kathy Selden (Debbie Reynolds). She drops him off, but not before claiming to be a stage actress and sneering at his undignified accomplishments as a cinema actor. Later, at a party, the head of Don's studio, R.F. Simpson (Millard Mitchell), shows a short demonstration of a talking picture, but his guests are unimpressed. Don runs into Kathy again at the party. To his amusement and her embarrassment, he discovers that Kathy is only a chorus girl, part of the entertainment. Furious, she throws a pie at him, only to hit Lina right in the face. Later, Don makes up with Kathy and they begin falling in love.After the first talking picture, The Jazz Singer, proves to be a smash hit, R.F. decides he has no choice but to convert the new Lockwood and Lamont film, The Dueling Cavalier, into a talkie. The production is beset with difficulties (most, if not all, taken from real life), by far the worst being Lina's comically grating voice. A test screening is a disaster. In one scene, for instance, Don repeats "I love you" to Lina over and over, to the audience's derisive laughter (a reference to a scene by John Gilbert in his first talkie[2]).Don's best friend, Cosmo Brown (Donald O'Connor), comes up with the idea to overdub Lina's voice with Kathy's and they persuade R.F. to turn The Dueling Cavalier into a musical called The Dancing Cavalier. When Lina finds out that Kathy is dubbing her voice, she is furious and does everything possible to sabotage the romance between Don and Kathy. She is even more irate when she discovers that Kathy will receive screen credit and a big publicity campaign, so she blackmails R.F. into withholding credit, and, later,...
