Air police sergeant

1960s airman accidentally beamed aboard

A United States Air Force security sergeant of the late 1960s who surprised Kirk and Sulu in a records room at the Omaha air base and was accidentally transported up to the Enterprise.

The unnamed air police sergeant appears in Tomorrow Is Yesterday, in which the Enterprise is thrown back to twentieth-century Earth. Kirk and Sulu beam into the Omaha installation by night to remove the film and tapes that recorded the starship.
The sergeant walks in on them, holds them at gunpoint and collects their equipment. Fiddling with a communicator, he sets off the signal that Spock takes as a request for beam-up, and he materialises on the transporter pad instead of the officers.
Rigid with shock, he says almost nothing aboard ship and is kept in the transporter room, where Kyle brings him chicken soup. He is finally beamed back to a moment before he entered the room, so that he remembers none of it. He was played by Hal Lynch.
