Henderson was one of the military personnel stationed at Icarus Base, under the command of Colonel Everett Young.



In 2009, he and 80 others fled the base after an attack against the base, and evacuated to the Ancient ship Destiny. (SGU: "Air, Part 1")

Later in 2009, he was assigned to guard the armory, a sensitive area on Destiny where the guns, explosives, and ammunition were stored. When Simeon killed Michaels and escaped to kill Ginn, he shot Henderson and another member of the military contingent also on guard there during his escape through the Stargate. Henderson was taken to the infirmary but Lt. Tamara Johansen was unable to save him. (SGU: "Malice")
