WASHINGTON Two U.S. Navy pilots were shot down over the Red Sea on Dec. 22 in "an apparent case of friendly fire," the American military has said. Both pilots were recovered alive but "initial assessments indicate that one of the crew members sustained minor injuries," the United States Central Command said. "This incident was not the result of hostile fire, and a full investigation is underway." CENTCOM said the guided missile cruiser USS Gettysburg "mistakenly fired on and hit the F/A-18"
