There were twenty half-hour episodes, seen bi-weekly. The last broadcast was on 29 May 1954.
Episode titles include "The Box"; "Revolt of the Machines"; "His First Command"; "Blaster Martin"; "Envoy of Death"; "The Glop"; "Into Thin Space"; "The Plague Ship"; "Tooth and Claw"; "The Wendigo"; and "The Q Effect", episodes one and two. Some of the episodes were either untitled or their titles have not yet surfaced.
In a daring move for the times, the Captain would occasionally step from fiction into reality, addressing the television audience directly from the stage of the Wanamaker Auditorium, the camera showing the empty seats (there was no studio audience).
No recordings of this series are known to survive.
