Hal Bishop

Commander Hal Bishop was in charge of SILOET during the late 21st century.

He was Colonel LeBlanc's second-in-command for eighteen months before taking over. Whilst returning Grant Matthews to the Myloki, he thought he saw his dead wife in the transition area to their dimension. He followed her, never to be seen again. (PROSE: The Indestructible Man)

Behind the scenes
Hal Bishop is a thinly-veiled copy of Colonel Ed Straker from Gerry Anderson's television series, who was played by Ed Bishop.
