passing information has not been aviation's strong suit. and I will admit that I didn't know you could rip the vertical fin off the plane while using the rudder. Mind you I've taken at least 9 FAA written exams and the subject didn't come up.
My airline was lucky in that we didn't have the Airbus 300 series.
But a crash in Canada and its causes on a different type was not transmitted to our airline in time to prevent a similiar crash.
that is one reason why forums like this are important, you just might learn something.
