F/A-22 Raptor 4001, the first of the Air Force's next-generation of air superiorty fighter jets, flew its 100th mission at Edwards, with Boeing test pilot Chuck Killberg at the controls. The F/A-22 is undergoing the most extensive and sophisticated testing of any combat aircraft ever developed, giving the Air Force and its industry partners adequate time to properly design, build and test the Raptor before being put into production.
