I grew up in So Cal I am 54 now so remember the drills at school ,we have Vandenburg A. F. B. a couple hundred miles away from us they would launch a rocket and left a beautiful vapor trail over the pacific ocean it wasn't till years later having a boss who worked in the space programs who told me there was a lot of stuff rotating around the earth for our protection and I need to thank the American "we can do it spirit" that propelled us ahead of the rest of the world and for Ronald Reagan scaring the crap out of the Soviets with his Star wars program ( which was impossible but they didn't know that) . Can we do it again?? I'm not sure. These sites are interesting . Thanks for the post
