Cliff flies to and boards the airship, but during the ensuing showdown, Jenny accidentally sets the bridge on fire with a flare gun. Sinclair holds Jenny hostage, forcing Cliff to give him the rocket pack, but not before he covertly removes the chewing gum patch, allowing fuel to leak near the rocket pack's exhaust. Sinclair dons the rocket pack and flies off, but the leaked fuel causes the rocket pack to catch on fire, causing Sinclair to plummet to his death on fire behind the HOLLYWOODLAND sign; the resulting explosion destroys the "LAND" part of the sign. Lothar is engulfed in flames as the airship explodes, but Cliff and Jenny are rescued at the last moment by Hughes and Peevy flying an autogyro.
