chunk: Garber, the sarcastic lieutenant Rico Patrone (Jerry Stiller), and other transit workers cooperate while trying to guess how the criminals intend to get away. The supervisor at Grand Central decides to confront the hijackers himself. As he approaches the train, Grey (Hector Elizondo) shoots him dead. Various clues surface for Garber: Blue has an English accent, while Green (Martin Balsam) has a cold and periodically sneezes over the radio, to which Garber says "Gesundheit." Garber surmises that as the hijackers are able to operate the train, one is probably a disgruntled transit worker. He also learns that one of the hostages is an undercover police officer.
