I cannot see why so many are opposing the two-crew rule.
This guy was emotionally weak despite his ability to hide his illness. Just the presence of cabin crew on the flight deck would have prevented this tragedy. Never ever would he have tried to overpower fellow crew. Only the thought of being entirely in control allowed him to carry out his plan.
I appreciate why many pilots perceive agency cabin crew with only two-week training as a potential threat and why the rule makes it easier for extremists to get past the cockpit door in flight.
However, as far as I am concerned thus far this rule has been successful in the US and to my knowledge there have not been any female suicide pilots, let alone loonie cabin crew trying to overpower flight crew. Not saying this will never happen though.
Why not further restricting the two-crew rule to only the purser allowed on the flight deck with only one pilot present and the door shut?
Being appointed the role of the purser requires longer employment with an operator plus a decent performance record. Also, cabin crew allowed onto the flight deck from now on are to undergo a more thorough background check including a more restrictive medical similar to a flight crew's.
