Airman Pearson is a male member of the United States Air Force who served in Icarus Base. In 2009 he was forced to evacuate the base by 80 other people after the base was under attack, and ended up stranded up Destiny several billion light years away.
After a day since he arrived on board, he was present at the observation deck with other crew members, who wanted to know what Eli Wallace knew, as Everett Young and Nicholas Rush trusted him. (SGU: "Darkness")
