after reading everything about this sad accident I call upon the NTSB to properly admonish the FAA and demand changes to enhance safety.
The FAA certified the aircraft and its manual(POH)
The FAA certified the airline operating the plane
The FAA certified the airline's training program
The FAA certified the pilot. And along the pilot's career had the opportunity to test the pilot's knowledge of rudder inputs and their effects many times...written and oral exams for the private, commercial, instrument rating, multi engine rating , airline transport pilot certificate and perhaps others including type rating.
regarding the SAC B52 incident, I think there was one another one due toloss of vertical fin leading to a crash somewhere near Cumberland Maryland about 45 years ago or so. I'll bet the pilot didn't rock the rudder!
