In all iterations of Star Trek, (TOS, TNG, DS9, VOY, ENT and the movies) how many transporter accidents or incidents, integral to the plot, have there been?

  • 1
    Would that be any episode with any transporter problem, or would it have to be central to that episode? Do the movies count?

  • @Politank-Z central to the episode

  • Off the top of my head, several per show. Tuvix. The one with Thomas Riker. Realm of Fear, the Next Phase, all of the alt universe ones like the Enemy Within, Rascals, Drone

1 Answer 1


Based on the criteria that an accident must occur and that it must be integral to the plot (e.g mentioned repeatedly or main plot driver), there are surprisingly few "transporter accident" episodes, only one or two per show.

For completeness, I've also lumped in those episodes where intentional abuse of the transporter occurs as the main plot driver


The Enemy Within - Transporter accident: Life creation
Mirror, Mirror - Transporter accident: Travel to Mirror Universe


Rascals - Transporter accident: Age regression
Realm of Fear - Transporter accident: Personnel trapped in matter stream
Second Chances - Transporter accident: Life creation
Data's Day - Transporter abuse: Faked death
The Next Phase - Transporter accident: Personnel trapped out of phase


Drone - Transporter accident: Life creation
Tuvix - Transport accident: Life creation / Moral dilemma


Our Man Bashir - Transporter accident: Personnel trapped in buffer
Through the Looking-Glass - Transporter abuse: Travel to Mirror Universe
Shattered Mirror - Transporter abuse: Travel to Mirror Universe
The Emperor's New Cloak - Transporter abuse: Travel to Mirror Universe
Field of Fire - Transporter abuse: Murder


Daedelus - Transporter accident: Death in transit
Vanishing point - Transporter accident: Trapped in buffer


Star Trek: The Motion Picture - Transporter accident: Death in transit x 2

  • So the answer is 16?

  • @user14111 - The figure is debatable. For example, is the transporter accident in ST: TMP plot integral or merely a device to explain the return of Spock. Does Data's Day count since there was no real transporter accident, etc etc.

  • So you haven't answered the question. It asks for the value of a certain integer.

  • @user14111 - As I've said, the major problem is that any numerical value would be meaningless without more closely defining the original question.

  • you should add ENT: Vanishing Point too as the whole episode was about the transport cycle being disrupted: therefore not a normal transport
