 The use of a General Dynamics F-16 Fighting Falcon mockup was a key element of the main characters escaping from a fortified town.The wooden, styrofoam and fibreglass mockup was built on an automobile chassis and powered by a 350ci Chevrolet engine.As with the first film, the novelization of the sequel was credited to Joan Wilder, the character played by Kathleen Turner; both books were actually ghostwritten by Catherine Lanigan.
