Great work Stephen and you're absolutely right, we're now able to have an intelligent conversation on 911 without getting emotional. I would recommend Dr Judy Wood's book "where did the towers go". It helped me to understand what could have happened to two of the tallest buildings on earth turned to dust. Not just the two towers. But, the buildings on the site.

The toasted cars, fine dust, surviving firefighters in the stairwell, no damage to the bathtub. These are just some of the questions that are asked in the book.
