I would personally be happier with a 39 inch katana (Japanese sword) - but it would be hard to get a decent swing on that blade in a cockpit. So a 16 inch bayonet (as a stabber) would be a good compromise.
However they have even taken away my "knock off" SAK (Swiss Army Knife) that came with the shaving foam - with its' pissy 2 inch blade, corkscrew and opener. So I can no longer open bottles of beer or wine - or even the odd hotel window.
So now I have to rely on the "woolworth" bolts that have been installed and if anyone makes it through those then I suppose it's either the teeth or throwing Jep books.
Sure I have other items on the flight deck I might use - but they are not really weapons per se. A little thought and innovation goes a long way - but what about something made for the job?
