The reason I asked is that, going forward, there'll be some sort of rule requiring two crew members to be in the cockpit at all times. But that won't mean much if some nut pilot is carrying a three-inch blade.
Of course a that pilot can still do great damage will a ceramic coffee cup, or with his bare hands. So maybe it's a moot point.
And it says something about the sick state of the world that this is even an issue.
There is no way to stop a pilot in the flight deck from doing bad things. Period. Put 10 people in the flight deck and you only increased the odds.
That is why, one of the requirements for hold an Airline Transport Pilot certificate is, “good moral character.”
Let’s face it, the most dangerous person in the world today is a malevolent anti-Semite who is setting the world on fire while he watches basketball. Whose going to stop him? Pilots going nuts are the least of our worries.
The U.S. has a two person rule. The airplanes all have a wicked crash axe in the cockpit. No need to bring your own.
Yes. A 98 lb female flight attendant sitting in the left seat will be useless against a 250 lb male co-pilot if malfeasance is the co-pilot's objective.
