David Bailey

David Bailey was a human Starfleet officer in the 23rd century, who served aboard the USS Enterprise under Captain James T. Kirk. In 2266, after the Enterprise made contact with Balok of the First Federation starship Fesarius, Bailey volunteered to join the alien as a form of cultural exchange. (TOS: "The Corbomite Maneuver")

In 2373, after over a century of exploring the galaxy with Balok, Bailey encountered the USS Voyager in the Delta Quadrant. Though extremely pleased to see other humans again (and to sample replicator cuisine), Bailey rejoined the Fesarius to continue his travels. (VOY short story: "Ambassador at Large")
