When asked how bad the situation was, Mason told Trumbull it was real bad and that all communications were compromised. He also told The Vice President that they are satellites over there, but they came up with nothing. Mason listened as Chairman of the Joint Chiefs of Staff General Edward Clegg send a drone has send visuals of the attack of London and when they saw the devastation of London, he was horrified by the sight of it. Mason was then relieved that Marine One is in the air with President Benjamin Asher aboard. Suddenly when Marine One was shot by terrorists with Stinger missiles, he was horrified when Marine One crashed into Hyde Park.
