All six US crew members of a KC-135 refueling aircraft that crashed while supporting operations against Iran are dead, the US military said yesterday. US Central Command said the crash in western Iraq on Thursday followed an unspecified incident involving two aircraft in "friendly airspace," and that the other plane landed safely. Ohio Governor Mike DeWine said in a social media post that three of the six crew members were from his state and were deployed with the Ohio Air National Guard's 121st Air Refueling Wing. The crash brings the US death toll in Operation Epic Fury to at least 13 service members, with the seven others killed in combat. The Pentagon said earlier this week that about 140 US service members have been injured, including eight severely. US Central Command said the circumstances of the crash are under investigation, but that the loss of the aircraft was not due to hostile or friendly fire.
