Skyjacked is a 1972 American disaster film directed by John Guillermin. The film stars Charlton Heston, James Brolin and Yvette Mimieux, along with an ensemble cast primarily playing the roles of passengers and crew aboard an airliner. Skyjacked is based on the David Harper novel Hijacked. This was the last of actress Jeanne Crain's 64 films. It was the film debut for several actors and actresses, including Susan Dey and Roosevelt "Rosey" Grier. Skyjacked explores the personal dramas and interactions that develop among the story's characters during a crisis that is endangering all of their lives. Plot During a routine flight to Minneapolis, a passenger (Susan Dey) aboard Global Airways Flight 502, a Boeing 707, discovers a bomb threat written in lipstick on the mirror of a first-class bathroom. Captain Hank O'Hara (Charlton Heston) believes it to be a hoax, but when a second handwritten threat is left on a stewardess's serving tray he is convinced to take the cryptic threats seriously and follows the instructions -- "Bomb on plane divert to Anchorage, Alaska. No Joke, No Tricks. Death"—by changing course for Alaska. To avoid an explosive decompression if a bomb goes off, he flies at lower altitude, increasing fuel consumption. The captain ignores a warning by a passenger, a jazz cellist (Roosevelt Grier), that he suspects his erratically behaving seatmate, Sgt. Jerome K. Weber (James Brolin), to be the hijacker. The weather at Anchorage is so poor, a United States Air Force ground-controlled approach specialist (Claude Akins) is called in. His radar shows a small aircraft with radio failure that is approaching the same runway, but Flight 502 has too little fuel to go around. O'Hara sees the other aircraft at the last moment and manages to avoid a collision and land safely. Once on the ground, passengers attempt to disarm Weber, a Vietnam veteran driven insane by war trauma. Whether he has a bomb or not, Weber is certainly armed with guns and grenades and manages to fight off an attempt by other passengers to disarm him and threatens to detonate a grenade in his hand if anyone attempts to interfere with his plans. Weber is taken to the cockpit where he demands the aircraft be refueled. While the hijacker is occupied in assuming control, the lead stewardess (Yvette Mimieux) oversees the escape of the economy-class passengers by emergency slide. Weber becomes outraged but allows the remaining passengers
