A '7700' distress signal was received from a Boeing KC-135 Stratotanker, a US Air Force 'flying gas station.' The emergency alert came while operating over the Persian Gulf region near Qatar, raising questions about what went wrong during the flight.
Flight tracking data from Flightradar24 showed the aircraft issued a '7700' squawk code, an internationally recognised transponder signal indicating a general in-flight emergency, while flying over the area between Iran and Qatar.
