Stronger than a locomotive, faster than a speeding bullet.
Clark Kent and Jimmy Olsen are taking their last ditch efforts to save a mystery plane that is to land at Bridger field. A secret machine has been invented that super heats the metal of an aircraft engine, to melt it and disintegrate it leaving no sign of the engine left in wreckage. Why? Just for the pure fun of sabotage I suppose.
Fearing that Clark will soon locate the cabin where the machine is located, the bad guys take their own desperate measures. Time has run so short that only minutes are left before the next plane arrives with its important passenger. When a rock slide starts, Superman has to spring into action to save Jimmy and his friends, before flying through the skies to get the bad guys.
Our evil geniuses mistake that object flying through the sky at them as their airplane. Then they realize its Superman. The plane is safe, Jimmy is safe, but the cabin and all that were in it were destroyed when the machine blew up.
Clark takes his friends back to safety and gets his scoop for the newsspaper. Stay tuned for more adventures.
