At the departure area, a Russian transport airplane lands outside to pick up the remaining Russians. Lewis orders Ridley to run after them and stop them from escaping. However, Ridley fails and the Russians board the plane. Lewis then contacts an ally US Air Force plane to destroy the transport.The Russian transport begins to take off, but is destroyed by the US plane. Lewis and his team are relieved with a mission success and he orders them to take a little break and maintain patrol around the airport.
