A Near Loss
I recall hearing about this incident a long time ago. During the testing/certification of the A-320, one of the test aircraft was almost lost. The pilots were doing some sort of testing at an altitude between 30-33K. For some reason, they got into a pitch up, wings level situation and couldn't get the aircraft to roll or the pitch to come down. Finally, they retarded the throttle on one engine to idle and the other to max thrust. The aircraft then started to roll and the nose came down. They got control of the aircraft at approximately 10K, not much room left.
