There are TSA agents that will search hundreds of people every day and die without ever finding anything. If you behave like that at a farm, the farmer shoots you before you can infect the other livestock. If you behave like that at an airport, the farmer commends you on your vigilance while your hand paws at his junk. I think everything about the way we fly is stupid, so I've developed an entirely new kind of airline. I'm so sure it's going to "take off" that I've already designed the "flyer"!
This should have resulted in years of therapy.
Sometimes it's just a matter of making the US Department of Defense look, like, REALLY cool.
Actual impending doom like global climate change or mass extinction just makes people bored.
