Yulya I will help you out with your question about 9/11. You can't really argue with me about it, because I was on a search & rescue team at the time and arived 10 min after second collapse. Here it is, with my own 2 eyes: 1. Tower 7 collapsed from structural instability as a result of the shock wave of first collapses, I was stading 20 feet away when it started shaking and ran with the rest. 2. Gold. It is not missing, if you wish I have a photo that I personally took of U.S. Marshalls carrying gold out of Federal Reserve. 3. People who were on lower floors ran faster, people without arms came out fast because 4 elevators were still working and they take 3-4 min to get downstairs. Any other questions ?
