The solution is to isolate the cabin from the cockpit. Take off with cameras watching the cabin. At the slightest hint of trouble, drop the cabin pressure and it's lights out for everyone. Then have your air marshals go and sort out the good from the bad.
“If we had armed air marshals and pilots before 9/11,...it wouldn’t have changed a thing. They would have targeted the marshals first and merely delayed the inevitable.”
nobody knows who the marshals are. Israel has been doing this for years. Of course you can’t just give them guns and assume they can handle it. They have to specifically train for shooting terrorists on a plane.
No, I don’t think taking out the cabin pressure is such a great idea.
