Superman [Clark Kent]; Lois Lane; Perry White; the Mayor of Metropolis
Synopsis
When Metropolis is threatened by a giant meteor, Superman must make preparations without inciting a panic. To do so, he disguises his actions as motivated by a desire for publicity.
Tommy is dishonorably discharged from the Planeteers when he has no explanation why his ship was destroyed. In company with reporter Lon Brett he sets off to chronicle the seven wonders of space. The seventh is elusive until Brett says they should describe it as an invisible planet. This provides Tommy with the reason his ship was destroyed and he is reinstated.
