What happens
Captain Bradford and Elaine are adrift at sea after their rocket plane sinks beside the Magic Island. They inflate a small rubber raft and patch a leak in it while they wait out the night, expecting an attack from the Euclidians. Aboard the rescue boat, Mrs. Gregory, Joan and Jerry search the dark water for them, and Jerry signals with a searchlight. The episode ends with the rescuers spotting a light answering their signal.
The open ocean near the Magic Island and the city of Euclidea, at night and into early dawn.
Characters: Captain Bradford, Elaine, Mrs. Gregory, Joan, Jerry, Johnson
Listen for: The signal exchanged by searchlight between the rescue boat and the adrift captain and Elaine, and the rubber raft's leak.
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.
