What happens
Superman searches for Professor Sturgeon, an atom bomb scientist who has been taken from New Orleans by air. Clark Kent, at the Brownsville airport, learns that the plane carrying the professor is overdue and has vanished. Superman flies out over the Gulf of Mexico looking for the converted army transport. Meanwhile, pilots Bill Ramsey and Bruce McMillan, flying the plane, grow uneasy about their two passengers, a doctor and a man who calls himself Polymer, whose cover story does not add up. The episode is part of The Adventures of Superman, first broadcast on July 11, 1946.

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.
