Capt. Derek Grenier, 9th Air Refueling Squadron KC-10 Extender evaluator pilot, stands in front of the airframe that he has flown 266 combat sorties and accumulated more than 2,200 combat flying hours. Grenier voluntarily disenrolled from the Air Force Academy in June 2001. After 9/11, he knew he needed to be a pilot in the Air Force and was granted re-admission.
