Rocket Pack

The Rocket-Pack is a twin rocket-powered jet back that appears in The Rocketeer and the upcoming animated series of the same name. It was originally a top-secret invention that was stolen by gansters, and at some point ended up in the possession of stunt pilot, Cliff Secord, who would later bare the name, the Rocketeer.

Specifications
The Rocket-pack is basically two rocket jets mounted side-by-side, and is worn on the back like a backpack. Its powerful enough to make a person fly like a rocket. It is controlled by two throttles, fitted to the gloves, and a helmet fitted with a rudder, helps the person steer.

The film
The original rocket-pack was stolen by two gangsters from Howard Hughes. During their escape from the authorities leading to an airfield, one of the fleeing gangsters hid the rocket-pack in a biplane, which would later be found by Cliff Seacord. During 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 biplane. He soon becomes a media sensation, but also sets Neville Sinclair and the FBI on Cliff's tail.

As the film goes on, Cliff learns from the rocket-pack's designer, Hughes, that it is a prototype similar to one the Nazis have unsuccessfully attempted to develop, and now they seek to steal it for mass production, depicting an army of flying soldiers invading the United States. Neville Sinclair is revealed to be a Nazi spy and threatens to kill Cliff's girlfriend, Jenny Blake is he does not surrender the rocket-pack to him. In his effort to rescue her, he is force to give up the rocket-pack, but not before secretly recoming the chewing gum patch, allowing furle to leak near the rocket-pack's exhaust. Sinclair dons the rocket-pack and flies off. The leaked fuel causes it to catch on fire, causing Sinclair to plummet to his death on fire. However, Cliff receives the blueprints for the rocket-pack after he is presented with a new plane from Hughes. This encourages him and his friend Peevy to build an even better one.

The Series
Kit's grandfather, Ambrose Secord, kept a similar rocket-pack hidden away, told by someone to hang on to until the next Rocketeer was chosen. When Kit received the Rocketeer's helmet on her birthday he unveils the rocket-pack to her, declaring her the new Rocketeer.
