I'm afraid
surely not, that I'm with
Kaptin M on this one...
nor do I have absolute faith that there are no bad apples in the pilot community just because they fly the planes
Any such bad apples do not need a weapon to take control of the the cockpit... They just wait until you go to the washroom, lock you out and they've cracked it.
How do you imagine that confiscating their nail clippers/scissors/Swiss army knife beforehand is going to affect the situation? And anyway, don't engineers have all kinds of dangerous stuff whilst airside as part of the tools of their trade? Can't they just give it to someone?
There is no joined up policy, because no such policy can usefully be made. It is a sop to the travelling public and most of us grudgingly accept that. Just don't expect me to be happy about it though.
