According to an Air Force briefing, the controls on an F-22A at Langley Air Force Base showed that the aircraft's canopy wasn't locking. After several attempts at opening and closing the canopy, on the final try it locked and jammed--trapping the pilot inside. According to the briefing, the 27th Aircraft Maintenance Unit then "consulted Lockheed Martin and the F-22A System Program Office to determine alternative methods to open the canopy and extract the pilot." The mission was accomplished approximately five hours later. While the "alternative method" ultimately used was fairly cheap, the resulting damage wasn't - the cost to replace the canopy is $182,205.
