What happens
Captain Bradford and the Gregory party fly a Euclidean rocket plane back to Los Angeles to collect materials needed for a formula that will let them take over the underwater colony of Euchlytia. Their pilot, Elaine, guides the craft through thick fog toward the city, and the group must find a body of water large enough to land on without being seen. Bradford radios their contact Johnson to arrange a meeting at Lake Hollywood, where the plane will come down. Elaine proposes using a fog ray to clear their path and sees the plane safely onto the lake. The party plans to hide the craft beneath the surface.
A Euclidean rocket plane flying from Euclidea toward Los Angeles, then landing on Lake Hollywood in fog.

Listen for: Elaine's fog ray clearing the path, and the balloon-assisted landing on Lake Hollywood.
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.
