a flame thrower and disables it, but Gog soon follows its twin to the reactor room to finish the job. Sheppard's flame thrower runs out of fuel as the robot advances on him. Dr. Van Ness arrives with another flame thrower, but the control valve sticks, and Gog now turns on him. Sheppard desperately begins using the nozzle of his flame thrower as a bludgeon, trying to smash the robot's electronic tubes. The now-crippled robot begins spinning back and forth, its arms thrashing about wildly. At that point, Gog suddenly comes to a halt, its metal arms falling limply to its sides. American F-86 and F-94 jet fighters have found and destroyed the enemy plane, ending NOVAC's reign of destruction. Van Ness then realizes that Sheppard and Merritt have been exposed to an overdose of radiation from the reactor. Sheppard takes Merritt (who has fainted as a result of all the stress she has experienced) into his arms and they head for the complex hospital, where it is determined that their exposure, while causing their film badges to turn red, was not serious, and that they will both soon recover. A few days later, Dr. Van Ness explains the situation to the Secretary of Defense, informing him that, in spite of all the setbacks, the project is still on schedule, and that a working model of the space station is about to be launched into orbit. The new "baby space station" will be equipped with telescopes and television cameras that will spot any further attempts to sabotage the complex. The Secretary notes with satisfaction: "Nothing will take us by surprise again!" The following morning, the launch goes off without a hitch.
