I am a movie director and I just received the following movie plot. Could you help me answer this question? If not, let me know by writing "Not answerable". Plot title: Destination Moon Movie plot: When their latest rocket test fails and government funding collapses, rocket scientist Dr. Charles Cargraves (Warner Anderson) and space enthusiast General Thayer (Tom Powers) enlist the aid of aircraft magnate Jim Barnes (John Archer). With the necessary millions raised privately from a group of patriotic U. S. industrialists, Cargraves, Warner, and Barnes build an advanced single-stage-to-orbit atomic powered spaceship, named Luna, at their desert manufacturing and launch facility; the project is soon threatened by a ginned-up public uproar over "radiation safety". The three idealists circumvent legal efforts to stop their expedition by simply launching the world's first Moon mission well ahead of schedule; as a result, they must quickly substitute Joe Sweeney (Dick Wesson) as their expedition's radar and radio operator. On their way to Moon, they are forced to go outside Luna in zero gravity, wearing magnetic boots to stay on the hull, in order to free a frozen piloting radar antenna greased-up by the inexperienced Sweeney hours before the launch. In the process they carelessly lose one of the crew overboard, untethered in free fall. He is cleverly retrieved by using the nozzle of a large oxygen cylinder as an improvised rocket motor. After achieving orbit around the Moon, the crew begins the complex landing procedure, using too much fuel during the Luna's descent phase. Safely on the Moon, they explore the lunar surface, reporting back by radio how their view of the Earth looks contrasted against the black lunar sky; one crew member photographs another pretending to hold up the Earth like a modern Atlas. The story takes a serious turn when they calculate the mass needed to lighten their spaceship in the Moon's one-sixth gravity in order to get home safely with their remaining fuel. No matter how much non-critical equipment they remove and leave on the lunar surface, the hard numbers radioed from Earth continue to point to one conclusion: Someone will have to stay behind on the Moon if the other three crew... My question: What are they wearing?
The answer to this question is:
Magnetic boots.
