An F-22 that had performed a flyover at a Pearl Harbor anniversary event, Friday, later scraped its tail on landing at Joint Base Pearl Harbor-Hickam, causing an estimated $1.8 million in damage to the jet. No injuries were reported. The damage estimate accounts for little more than one percent of the fighter’s $143 million per unit cost as estimated by the Air Force … and even less of the jet’s $412 million per unit cost as estimated by the Government Accountability Office.
