A US F-35 fighter jet crashes near a military base in the San Diego area on Friday, according to multiple reports. Officials say the pilot ejects from the aircraft before it impacts, which prevents the jet from hitting the base directly. The available accounts do not provide details on the cause of the crash, the extent of damage on the ground, or whether there were any injuries among base personnel or civilians. The reports identify the incident as occurring near a California military installation in the San Diego region and describe the outcome as a successful ejection by the pilot. No further operational or investigatory findings are included in the provided summaries. With limited information across the sources, the key confirmed elements remain the location near a San Diego military base, the aircraft type (F-35), and that the pilot ejects prior to impact.
