What happens
Commander Buzz Corry and Happy Jackson, members of the Space Patrol, land secretly on the planet Planet X to destroy a warning tower operated by the ruthless Prince Baccarati. Their meteor-disguised ship lands far from the tower, and they cross a dangerous valley of dread filled with man-eating vines and monsters. Baccarati, meanwhile, forces captured men from the United Planets to work in his mines. The two Space Patrol officers push on toward their target through the hostile terrain.
Planet X, a remote planet beyond the orbit of Pluto, including the Valley of Dread and Baccarati's Arkpike mine
Characters: Buzz Corry, Happy Jackson, Prince Baccarati, Dr. Melangro, Captain Jekyll
Listen for: The vine attack in the valley and the sound of the warning tower plot, as Corry and Jackson fight their way toward the tower.
Written from the episode itself; it never gives away the ending. Every recording is remastered for the stream: cleaned of rumble, hiss and mains hum (and the old TV whine where we found it), then levelled in two passes to steady broadcast loudness, so one show is never quieter than the next.
