The Popular Mechanics articles caused a brief Moonbat depression until they realized that the writer of the article (or is it the publisher of the magaizne? can't recall offhand) is Michael Chertoff's cousin.
Do a Google search and you'll find this whole article dismissed with such headlines as "Popular Mechanics' Deceptive Smear Against 9/11 Truth".
No self-respecting Moonbat believes a word of it.
"self-respecting Moonbat"??? Surely a contradiction in terms...
