Well done, Duster
Until there's two secure doors with an interlock, it's possible for a martial arts trained bad guy to muscle aside a pilot reentering the cockpit in a surprise move, latch the secure door behind and take out the remaining pilot protected from any further interference from the remaining crew and passengers.
Until there's two doors, I don't want anybody but crew in the forward galley as crew entering the cockpit are vulnerable to a surprise attack.
Now once a hijacker pulls this off and an F16 is called in, Duster will become another famous underling that management ignored.
I'm sure he and many others would be much happier if management clued in before rather than after.
