The Rocketeer movie

In the years leading up to World War II, stunt pilot Cliff Secord takes a trial run in a Gee Bee racing aircraft to prepare for an upcoming air show. But he accidentally comes into possession of a rocket-propelled backpack much coveted by the Nazis. With the aid of his mechanic pal, he gets it up and running, then uses it to foil a plot by a gang of vicious Nazi spies led by Timothy Dalton. Jennifer Connelly is on hand as the love interest, but the real fun here is when the Rocketeer takes off. Theres also a nifty battle atop an airborne blimp to defeat his foes who are anxious to use the device in an evil plan to rule the world! The dangerous mission transforms the ordinary young man into an extraordinary hero.
