Use the Emergency Override as mentioned in the Lockheed Martin F-35 Lightning II User Manual, should be one in the glovebox under the pistol, or in the F35B under the seat, then aim towards military controlled open test land, turn down the cow pie, hit the engine switch, and eject. If no NATO controlled land is nearby then aim for something really hard or try to coast by until you find some.
