What happens
Superman, disguised as reporter Clark Kent, investigates a sabotage plot at the new Happy Land amusement park. Nancy Bardet has taken the first ride on the Sky Chaser roller coaster to prove it safe after circulars warned the public away from it. Superman finds that a section of track has been removed and races to replace it before her car reaches the spot. Meanwhile, Kent tracks down Kelly, the park superintendent, who has been working with Midway Martin, the rival owner of Carnival Town, against Happy Land. The episode is part three of a serial in the Superman radio series, first broadcast on July 12, 1940, with its lead actors not named in the transcript.

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.
