(written from a Production point of view)
Stan Barrett (born 26 June 1943; age 74) is an actor, stuntman, stunt coordinator, and race driver. He portrayed a Sarpeidon jailer in TOS: "All Our Yesterdays". He filmed his scenes on Monday 23 December 1968 at Desilu Stage 10.
On December 17, 1979, Barrett set the land speed record at Edwards Air Force Base in California, achieving a velocity of 739.666 mph and breaking the sound barrier. However, this was an unofficial record attained without sanction of the USAF.
He may be the first Star Trek performer to have had any sort of connection with NASCAR. For besides the fact that his son is a NASCAR driver, he and actor Burt Reynolds co-owned a team for which Harry Gant was the driver.
Stan is not related to Majel Barrett.
