there is a long-standing problem with creating vehicles which you intend AI to fly. creating an empty vehicle is easy enough, but to create an airplane in flight requires enough time for the AI to be moved into the pilot's seat, realise he should be flying, switch on the engines, and begin flying in the right direction, all before the plane plunges into the ground.
are you sure you need to create it? why not simply have it flying around elsewhere? or at an airfield, ready to take off? that way you can control it using standard waypoints and switch triggers.
