Task: Question Generation
Input (English): In 1938 Los Angeles, two gangsters in Eddie Valentine's gang steal a rocket pack from Howard Hughes. During their escape, they find themselves on an airfield, where they hide the rocket pack, ending in an auto-airplane accident while escaping, with the police in hot pursuit. Stunt pilot Cliff Secord, whose Gee Bee racer was totaled during the accident, and airplane mechanic Peevy later find the rocket pack hidden in a bi-plane cockpit. Meanwhile, well-known actor Neville Sinclair, who hired Valentine's gang to steal the rocket pack, sends his monstrous henchman Lothar to question the injured getaway driver, who tells him that the rocket pack is at the airfield.Cliff's aspiring actress girlfriend, Jenny Blake, has a bit part in the latest Neville Sinclair film. On the set, Sinclair overhears Cliff attempting to tell Jenny about the rocket pack, so he invites her to dinner. Afterward, at a local air show, Cliff uses the rocket pack (and Peevy's newly designed face-hiding finned helmet) to rescue his friend Malcolm, who is drunkenly piloting a bi-plane. Having been seen by the newsreel press in the airshow audience (and Valentine's gangsters), "The Rocketeer" becomes a media sensation.Sinclair sends Lothar to Cliff and Peevy's home to find the rocket pack. The FBI arrives, but Cliff and Peevy escape, while Lothar steals its detailed schematics drawn up by Peevy. Later, at the airfield diner, Cliff and Peevy, trapped by several Valentine mobsters, learn that Jenny had a date with Sinclair, and of the actor's involvement in the hunt for the rocket pack. The diner patrons overpower the gangsters, while a bullet ricochet punctures the rocket's fuel tank, which Peevy temporarily patches with Cliff's chewing gum.[Note 1]At Sinclair's home, Jenny discovers that he is a Nazi secret agent, and Jenny knocks him out. She is later detained and forced to leave a message for Cliff to bring the rocket pack to the Griffith Observatory in exchange for her life. Just before he is arrested by the FBI and taken to Howard Hughes, Cliff hides the rocket pack. Hughes reveals his rocket pack is a prototype, similar to one that Nazi scientists have, up to now, been unsuccessful in developing. When Secord asks why there is so much interest in the rocket pack, Hughes shows a horrifying propaganda film depicting flying soldiers invading the United States and hoisting a Nazi flag over the White House. When Hughes demands the return of the rocket pack, Cliff explains that he needs it to rescue Jenny; he escapes, inadvertently leaving behind a clue to where he is headed.Cliff flies to the rendezvous, where Sinclair demands that Cliff give him the rocket pack. Cliff divulges to the mobsters that the actor is a Nazi spy; Valentine turns his weapon on Sinclair and Lothar, but Sinclair summons 60 heavily armed Nazi S.A. commandos hidden at the observatory. The Nazi rigid airship Luxembourg appears overhead to evacuate Sinclair. FBI agents suddenly announce their presence, having secretly surrounded the area; they and the mobsters join forces to battle the Nazis. Sinclair and Lothar escape, dragging Jenny with them aboard the airship.Cliff flies to and boards the airship, but during the ensuing showdown, Jenny accidentally sets the bridge on fire using a flare gun. Sinclair takes the rocket pack to save himself, saying "I'll miss Hollywood". However, Cliff has removed the makeshift chewing gum patch from the tank, which is now leaking. The fuel catches fire, and the fire follows the vapor trail to the rocket pack's fuel tank, which also catches fire, causing Sinclair to plummet to his death near 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.Hughes later presents Cliff with a brand-new Gee Bee air racer and a fresh pack of chewing gum. As Hughes leaves, Jenny returns Peevy's rocket pack blueprints, which she found in Sinclair's home; Peevy decides that, with some modifications, he can build an even better one.
