Star Sapphire Carol Ferris

Carol used to be a pilot, but, after her father retired, she gave it up to run the family business (Ferris Air, a company in Coast City that makes aircraft). She hired her childhood friend, Hal Jordan, as a test pilot. Soon after Hal became a Green Lantern, Carol found herself possessed by a Star Sapphire gem. The gem gave her power, but also altered her personality when used. After the formation of the Star Sapphire Corps however, Carol has been able to remain herself and act as a hero.
