chunk: The three dead hijackers are identified, and it is clear that none had piloted trains, so Garber concludes that the remaining hijacker must be the former transit employee. Working their way through a list of former motormen "discharged for cause", Garber and Patrone pay a visit to Harold Longman (Green), who bluffs his way through the officers' questioning. The officers find Longman's alibi weak, but start out the door, until Longman sneezes and Garber says "Gesundheit." Garber re-opens the door, and his expression indicates that he has found the final hijacker.
