 When Roddenberry began to develop "Star Trek", he sent Ingalls a series outline but asked him to keep it "very, very confidential".Ingalls went on to write two scripts for "Star Trek", his first being "The Alternative Factor".His second script, "A Private Little War", was intended to be a criticism piece on the Vietnam War, but was heavily re-written by Roddenberry to the extent that Ingalls was angry at him for a year and insisted on being credited only under the pseudonym "Jud Crucis".
