Green Lantern's Secret Codename Means More Than You Think
Hal Jordan, DC's most famous Green Lantern, is also an Air Force pilot when not engaged in superheroics — and his callsign contains multiple secret meanings of which even diehard fans of the character are not aware. The superhero is one of many military veterans in comics — Captain America, War Machine, and Captain Marvel immediately come to mind from the Marvel Universe — and as such, has a callsign like other pilots.
