I could have made more money flying the A300 with our company but didn't trust it like I did Boeing so stayed put. Everybody has to make their choices in life. I am glad I stuck with Boeing. Our copilot that got blamed for the JFK accident was a scapegoat. The vertical stab that was defective and patched out of the factory broke where the repair was done. I don't think the FDR can compensate for a fluttering VS about to leave the aircraft. I think if the back of the vertical stabilizer gets loose the rudder then becomes a trim tab so right rudder input gives left yaw. How would the pilots know that the VS was coming off?
