This is absolute madness. For the first time ever I feel unsafe. Any aircraft with humans on the Flight Deck can be crashed, with or without captain/copilot/cabin crew present.
I had once a cabin crew (male) stopped by security somewhere in the East.He was carrying a replica Berretta 9mm. Few years back.Was he suffering from some mental disorder? Probably...Was he hired by the company..? Definitely.
Yes, he was fired, obviously.
