Before settling on the lunar roving vehicle to provide mobility to Apollo astronauts in later lunar landing missions, NASA explored a variety of concepts including personal rocket packs to allow astronauts to fly to destinations in the vicinity of the lunar module. Both Bell (developer of the Bell Rocket Belt which, among other demonstrations, appeared in the 1965 James Bond movie Thunderball) and North American Rockwell received study contracts for one-man flying vehicles which could be stored in a bay of the lunar module descent stage (as the rover was eventually carried), deployed, unfolded, and flown.
The designs were detailed and involved ideas such using leftover propellants from the lunar module descent stage to fill the jet pack and providing a fabric launch pad so regolith ejected during takeoff and landing would not sandblast the lunar module.
