Synopsis for Challengers of the Unknown: "The Day the Earth Blew Up!"
While taking on a mission to investigate weird happenings at an abandoned military outpost in the arctic, the Challengers stumble upon a spaceship controlled by the alien Tyrans who are preparing to use their advanced technology to reverse Earth's gravity and eject all it's people into space to make for a quick takeover. Using hypnosis to get one of the Tyrans to do their bidding, the Challengers escape the alien craft and warn the military of the aliens plot to take over the Earth. With the help of military resources, the Challengers manage to fight off the invasion and destroy the alien ship. Saving the day, the story is covered up so as not to incite public fear, and Professor Haley gets a cold for all his trouble.
