"We're gonna get to the bottom of this, even if it means employing a little deception."
— Police Commissioner Garfield

"30 Minutes After Noon" is the seventh episode of Thunderbirds Season 1, originally broadcast on 11th November 1965. It was the 18th episode produced.


A mysterious fire in an office building turns out to have been a test of a new explosive device by a dangerous criminal gang. A British agent infiltrates the gang in an attempt to prevent its members from destroying a nuclear depot, but his cover is blown and he is trapped in the explosive-rigged depot.

  • All Security Robots in this episode were the same puppet; a minor redesign of Brains' robot, Braman, previously seen in Sun Probe.
  • This is the first and only appearance of two pod vehicles: The Dicetylene Cage, and the Laser Cutter Vehicle.
  • Glen Carrick Castle previously appeared as McGregor Castle in the Stingray episode Loch Ness Monster and appears again as part of Glen Garry Castle in the Captain Scarlet And The Mysterons episode The Trap.

  • This marks the first use in the series of a hand in the same frame as a puppet character: during the scene where Southern plays with his pen, a real hand plays with it in the foreground while the characters of Kenyon and Dempsey appear in the background.
  • Although he did not write this episode, it is possible Dennis Spooner may have borrowed ideas for an episode of The Professionals. In that, Bodie and Doyle have to prevent a bomb from exploding at 12.25am, destroying London.
  • The faces of Sir William Frazer and the Erdman Gang Member who Southern meets are never seen; only their hands appear on screen, when Sir William hand the pen to Southern, and when the Erdman Gang Member fastens the bracelet to Southern's wrist.
  • The rendezvous point where Southern receives his bracelet would later be seen as the Thompson Tower in City Of Fire.

Alternate VersionsEdit

Thunderbirds The ComicEdit

In 1992, several episodes of Thunderbirds were adapted into comic book format for Fleetway's Thunderbirds The Comic series, with 30 Minutes After Noon among the first. Written by Alan Fennell and illustrated by D. M. Stokes, the 12 page adaptation was spread over 3 issues, emulating the presentation of the 1960's TV Century 21 stories.

For this compressed version of the episode, 8 pages were entirely dedicated to Thomas Prescott's subplot, while the remaining 4 swiftly detailed the "Erdwing Gang" (sic), and Southern's rescue from the Security Robots.
