I don't fly much, because I hate the TSA and .... I hate the TSA.
Anyplace that won't let a gentleman have a pocketknife is one place that gentlemen need not go. I was raised to believe that every man worth his salt carries a pocketknife. Don't even get me started on guns.
However, if you've been paying attention at all, you know that the only weapon you truly carry with your everywhere is your brain. Everything else is a tool. And, it turns out, the TSA retards are just now figuring out that everything is a weapon.
Serving several years as a corrections officer taught me that the human capacity for weapons manufacture is unlimited. If someone goes jihad on a plane, stick a plain Bic pen in his sternum. If you can hold him down and hammer it in with a paperback book, it'll be cleanup on aisle four. For an easier task, get behind him and put it in a kidney. That'll change his focus real quick.
Don't want to get that close and personal? From your carry-on, take out a bottle of shampoo, or a bar of soap. Drop it in the toe of your pantyhose (or your socks) and use that as a bludgeon. If you can get a good lick upside his head, he'll be drooling on himself in federal custody.
Another example; you know that little air hose the stewardess uses during the safety briefing? When you've got the clown down, use that on his neck. When he goes limp, use some pantyhose (the one with the soap in it will do fine) and hog-tie him.
Your brain is the weapon. Use it.
Thanks to Say Uncle and the Munchkin Wrangler for the heads-up.
