Perhaps someone can enlighten me about whether political economists are the best people to review a document that would require knowledge of the effects of explosives, reaction of materials to intense and prolonged fire in an enclosed space, etc.  In fairness, I should add that perhaps the editor of The Hidden History of 9-11 has assigned scientific peers to review the paper.

I have a very good dentist but would not go to him for brain surgery or for a software problem.
