Prison Break was an 18-page Star Trek: The Original Series comic strip. It was the 23rd weekly story arc in the UK comic strips series, published in six installments in TV21 Weekly in 1971. This was the fifth of six stories drawn by Vicente Alcázar and Carlos Pino. In this story, four murderers escaped from a Federation penal colony.

Publisher's descriptionEdit

Teaser, August 7, 1971
While the starship Enterprise lay in orbit above the prison planet of Certax, undergoing repairs, four convicts — Jarman, Mendoza, Kelly and Schirach — had smuggled themselves aboard...


The Enterprise's number six warp reactor suddenly blew apart. While putting out fires, crewman Corcoran was accidentally exposed to lethal levels of radiation. Captain James T. Kirk diverted the starship to the nearest Federation port with hospital and engineering repair facilities, which turned out to be Certax, a penal colony.

Four of the convicts learned about the situation in orbit above them. They killed a guard and four engineering technicians, then slipped aboard the Enterprise as part of Certax's repair crew. They held the bridge crew at gunpoint and locked Montgomery Scott and Nyota Uhura in a storeroom under guard. The colony governor warned the ringleader, Cal Jarman, that he would not hesitate to fire missiles at the Enterprise if he did not surrender.

Jarman retaliated by threatening to drop the irradiated warp reactor onto the colony, which would strike like a nuclear bomb. Kelly suggested that they bomb the colony anyway, and left with Mendoza to arrange it. Leonard McCoy found the two convicts entering an airlock. He'd hoped to knock them out with an anesthesia gas gun, but they were wearing environmental suits. McCoy filled two syringes with a drug and followed them in an EVA suit into the shuttle bay, where the damaged reactor had been stored within a lead container. During his confrontation with the criminals, McCoy punctured their suits, and they fell into space along with the reactor.

The reactor struck the port side of the secondary hull and broke apart, scattering irradiated material and shaking the Enterprise. Jarman lost his balance, and Kirk and Spock subdued him. McCoy gassed the fourth convict, freeing Scott and Uhura, but lethal radiation outside the ship posed a serious danger to the crew. A repair shuttle arrived from Certax with one technician aboard. It was Corcoran, the dying crewman – he salvaged the debris and then gave a salute, sacrificing his life to save the ship.

  • The damaged reactor's location was inconsistently located. Kirk stated it was in the port nacelle, as depicted in artwork. However, narration as well as dialogue from Chekov and Spock placed it in the starboard nacelle.
  • The Enterprise was shown with the registry NCC-1701-B on the first segment's cover.
  • At one point Montgomery Scott alerted the crew over the intercom to look out for four lost Certax engineers. Oddly, this took place before the engineers had boarded the ship. Two pages later, James T. Kirk assumed command just as Uhura received a report that the four engineers were lost. Kirk said he would alert the crew, but instead announced that the engineers' shuttle was now docking. The two dialogue balloons had been swapped.
  • Colonel Strang had white hair when he met Kirk and Spock, but blond hair later in the story.
  • Schirach spoke with a thick German accent in the July 17th segment, but had no accent in the August 21 segment.
