I think what was and is the most frustrating about situations like Septemper 11th is there is nothing you can do but watch it happen. I believe all here would be proactive in a situation where you could, physically, make a difference. It is just the nature of Americans, especially the "gun culture". September 11th wasn't one of those situations. Collectively as a nation we watched as the events of that day unfolded in an era with a 24hr news cycle. There were plenty of images and angles. We were left to our own devices as far as action. There was no sense to be made of the senseless.
At the time I was working in a screen printing shop. We mostly printed vinyl decals for colleges. Everyone in the shop (all three of us) just listened to the radio. As you might imagine, not a lot of production was completed that day. There was no real drive considering the situation. As Conagher 45 refered to earlier, the flag was something that sprouted out everywhere overnight. It gave everyone some comfort an a symbol to rally around. For the next month we printed American Flag decals. All of our retail stores were demanding them. We even printed some smaller flags for football helmets. That shop (and most of my work clothes) were covered in Red, White, and Blue. Talk about therapy, that was the easiest and fastest month of my tenure there. I have seen our flags all over: All the sherriffs and police crusiers and fire trucks here in Gainesville, cars, store fronts, etc. We were even told by one of our retailers in Atlanta that several were put up in Delta cockpits. The only thing better would be to know some of our flags were in a different cockpit over different airspace.
My '90 Jeep Wrangler (YJ but that is a different forum) sported one 'till she left my driveway and her younger sister ('06 Wrangler Unlimited, damn wrong forum again) got one the day she arrived and still proudly wears one today. So, if you have an American Flag that says fantastic statics in the corner, you know one of the people responsible.
I am reminded everytime I get into my vehicle that September 11th is not a day, its a war cry.
