The pilot is responsible for the safety of the lives of the passengers on the flight. If as a pilot you accept this responsibility you are duty bound to ensure (as much as you can) that the other people do not die or are not harmed. This is an absolute
Is it an absolute? If so, why do planes crash? Is it because all crashes involve pilots who don't take their responsibilities seriously? Or because pilots make mistakes.....just like Ghandi, Schumacher, Tiger Woods, Michael Jordan, Chuck Yeager , Mother Theresa and Nelson Mandela?
Summary dismissal is the only response in this situation.
What about adding one more response? Like investigating how two humans log 30,000 boring flight hours and then do this?
