Action Comics#271(1960)

When a strange alien ship appears over Metropolis, Clark Kent and Lois Lane are sent to get the story. Clark manages to slip away briefly and change into Superman and attempts to stop the ship, and see who is inside, but his x-ray vision cannot penetrate it, so he joins back up with Lois as Clark Kent. The ship continues to fly about the city performing good deeds all around. Superman continues his investigation, and eventually the alien ship stops and tells the people of Earth (projecting an image of one of the aliens) that it's from Dimension X and that they have come seeking Superman's aid stopping a super menace in their realm. Believing the story, Superman willingly walks into a trap set by his nemesis Lex Luthor. In reality the lead ship is only sent to the desert far away from Metropolis, and Luthor (using an exchanger device to switch with a robot duplicate himself while in prison) begins new criminal operations in Superman's absence. When Superman learns the truth, and before he attempts to smash out of the satellite, a recorded announcement from Luthor explains that the any attempt to escape the shuttle will cause a neutron bomb planted in Metropolis to explode. To further his own ends, Luthor has a robot duplicate of Superman return to Metropolis and proclaim that the people of Dimension X require Earth's nuclear arsenal to destroy the menace that threatens their world, and for his own personal amusement, Luthor has the Superman robot toy with Lois Lane's emotions by asking her out on a date and kissing her. Luthor intends to use the nuclear bombs to hold the world hostage and make himself ruler of the Earth. However, Superman finds a way out of his predicament: Hearing a thunderstorm, he uses his super-powers to knock the satellite into the path of a thunderbolt, which fries it's inner workings allowing Superman to break free and easily foil Luthor's plot, returning all the nuclear weapons, rounding up his gang and smashing Luthor's robot duplicate.
