Amazon.com and Barnes & Noble removed review of "Firefight: Inside the Battle to Save the Pentagon on 9/11"

I had submitted a review of "Firefight — Inside the Battle to Save the Pentagon on 9/11" to Amazon.com and Barnes & Noble after attending a talk by the authors (where they refused to answer my questions).

I don't recall the history of the review at Barnes & Noble. The Amazon.com review was accepted, published, and was on Amazon.com for months. It's no longer there. Is this more of the coverup of 9/11?

You may read the review at The Wisdom Fund.

And if you really want to know what happened on 9/11 at the Pentagon, come to the National Security Briefing on July 11.
