Hal Jordan is described as a former test pilot in the DC series Lanterns. He is also a legendary Green Lantern who is approaching retirement.
Jordan serves as the experienced partner and mentor to John Stewart, a new recruit whom he is training. The show’s creative team drew inspiration for this version of Jordan from Chuck Yeager as portrayed by Sam Shepard in The Right Stuff.
John Stewart has a different background: the series describes him as both a Marine and an artistic architect. Guy Gardner is another Green Lantern, played by Nathan Fillion, while Thaal Sinestro is Jordan’s former mentor. Their shared Lantern identities can make the characters easy to confuse, but the test-pilot detail belongs specifically to Jordan.
