An air-traffic controller (Tim DeKay), on edge following a crash he might have caused, takes his fellow controllers hostage as they're working. His demand: He wants the NTSB tapes, which he thinks will prove he wasn't responsible for the crash. And there's something else bugging him, too. Meanwhile, Matt and Emily try to sort out their relationship, but Cheryl just wants them to end it. Joe Suser: Joe Spano. Cathy Barnes: Stacy Edwards.
