Lloyd Haynes played Lieutenant Alden, the communications officer of the Enterprise, in the second Star Trek pilot, Where No Man Has Gone Before.
Lloyd Haynes (1934–1986) is best remembered as the teacher Pete Dixon in the series Room 222. Early in his career he was cast in the second Star Trek pilot, Where No Man Has Gone Before, filmed in 1965.
He plays Alden, who mans the communications station on the bridge as the Enterprise approaches the barrier at the edge of the galaxy. Later he helps Kelso to bring the damaged ship's systems back into service while it is in orbit of Delta Vega.
When the series was commissioned the communications post was recast, and Nichelle Nichols joined as Uhura. Alden was not seen again.
