CNN  —  Multiple US B-2 bombers appear to have taken off from Whiteman Air Force Base in Missouri on Friday night and are heading west, according to flight tracking data CNN has reviewed, as President Donald Trump weighs his military options over a potential airstrike in Iran. A US defense official said there has been no order given to move forward with any kind of operation against Iran using the B-2s. As of Saturday, the planes are flying over the Pacific and appear to be headed toward Guam.
