SEASON 6, EPISODE 611 - Rush and the team investigate the 1960 case of a murdered stewardess and discover many hostile suspects who resented that she was trying to organize a stewardess union. The team questions former airline colleagues of the victim, including Helen McCormick (Golden Globe Award nominee Adrienne Barbeau - "Carnivle," "The Drew Carey Show," "Maude"), Gloria Flagstone (Emmy Award winner Mariette Hartley - "The Incredible Hulk," "The Rockford Files," "M.A.D.D.: Mothers Against Drunk Drivers") and Dean London (Golden Globe Award nominee Lee Majors - "The Six Million Dollar Man"). David Giuntoli ("Privileged," "Without a Trace") also guest stars as Dean London, as he appeared in 1960. Plus, Rush's father, Paul Cooper (recurring guest star Raymond J. Barry - "Walk Hard: The Dewey Cox Story," "Training Day") appears.
