Point, If EVER there is a question of safety of flight. put the aircraft somewhere safe and take the time Think.! Say right up loud and clear. Captain I think this is UN safe!! Then offer a safe place to think/ Reveiw. comunicate. If the captain blows you off. don't let him/her kill you. If he/her doesn't like this. its time to talk/question the company. Or quite and find another job.
