Legitimate autority of the Captain still exists
Roulishollandais: In general, yes, but there's not legitimate authority to command and force you to do the wrong thing, especially crash the a/c. "I was only obeying orders." is not a defence. Are you suggesting that a captain has the authority to force an F/O to disobey SOP's or execute bad airmanship in an unsafe manner; or to do so himself without being opposed?
