Not that it is directly relevant to this incident, but the NTSB report on the National Airlines DC-10 N60NA accident over New Mexico is incredibly frightening in terms of the malfeasance it suggests occurred by the airline's management, its maintenance staff, its flight crew and (somewhat) its cabin crew. I certainly hope that now 40+ years on, procedures and professionalism have improved substantially. That National Airlines is now dead does not seem saddening. See:
