Tu-154-B2 first flight after being stored for 10 years. Shortly after takeoff control system went nuts, and plane almost lost control. Pilots managed to land the bird in one piece.
Rumor is aileron feedback problem - system treated any aileron motion as external force, and attempted to "correct". Rudder was the only fully functional control.
