Source: The reason given for Wednesday's grounding of 452 F-15 Eagle fighters by the US Air Force. The USAF says the ongoing investigation into what brought down a Missouri ANG Eagle on November 2 has revealed a potential problem through the F-15 fleet. Investigators are concerned with longerons -- or metal rails -- that hold the F-15 fuselage together. Those parts were flagged by investigators early on, as officials ordered the entire fleet of F-15s inspected for possible airframe fatigue damage. The grounding comes one week after the USAF cleared F-15s to resume normal operations, following an initial grounding in the wake of the November 2 accident.
