Hello Simon,

A comment thread like this is not the place to have a full-up discussion of these issues at the level of detail you are looking for. Also, I am not the one to answer every question about every aspect of the events. Check out my web site, http://911speakout.org, and sites like http://scientistsfor911truth.org, or http://ae911truth.org as starting points for more scientifically reliable information.
