&gt; <i>If we didn&#x27;t have greater security for air travel aircraft would rain from the skies.</i><p>Did something changed fundamentally about human condition after 9&#x2F;11? Planes didn&#x27;t generally get attacked before, and they didn&#x27;t generally get attacked after. There were a few incidents on <i>both</i> sides of 9&#x2F;11. I don&#x27;t see any reason to attribute things going as they always have been to security theatre erected around the 9&#x2F;11 events.<p>&gt; <i>I think you might be blind to a whole layer of the infrastructure because you never have visibility into it.</i><p>I might be. Please share some details then, I&#x27;m always eager to learn something new and reevaluate my opinions.<p>&gt; <i>Today, not so. I don&#x27;t know how much you travel. If you do, be thankful there are people who did their best to ensure someone isn&#x27;t shipping an incendiary device on the same plane you and your family happen to be on.</i><p>I do travel enough, mostly on business. I am very thankful to all people ensuring my safety in air and on the ground. But I do question a lot of the efforts that were introduced as a reaction to events of 9&#x2F;11.
