Are you in favor of Senator Mike Gravel recommending a ''real'' investigation of 9/11 by non-aligned citizens?

I think it needs to be brought back up yes, i was at a conference a long time ago which had a lot of evidence, from eyewitnesses and structural engineers, those things were built to withstand an aeroplane collision, the idea was put into the plans after the empire state was hit. How did the "fire men" in the famous video know that building 7 was going to collapse hours before it did? without being anywhere near any kind of explosions or fire.
