Stupidity and hysteria does not protect airplanes.
Well, we've had no successful terrorist incidents on US air carriers since 9/11.
We've also had eight and a half straight years of stupidity and hysteria courtesy of the TSA, under both GOP and Rat administrations.
Now you and I know that correlation < > causation, but the sheeple don't, so I expect more and more stupidity and hysteria in future.
