Where did you study engineering or even take one class in chemistry or physics?I have watched loosescrews change and I have also dealt with the issue of building 7 and other issues brought up in it in previous posts. Have you read activistnyc on the issue of 911 or publiceye.org . Both of these sites deal with both sides of the issue rather than just dismissing alternative theories like curezone members . They also post interviews with Griffin and others who believe that 911 was an inside job.
