I am sure you all know that the 9/11 Commission Report is available in soft cover just about anywhere.  The price is very reasonable -- $10.
I bought it for a long plane flight, suspecting it could be a sleep aid if nothing else.  I was very impressed with the writing -- it reads a lot like a novel.  Its a very good read and contained a lot of info I had never heard.
The first chapter is a chilling account of the hi-jackings.  A later chaper is a detailed account of the aftermath of the impacts on the towers and the pentagon.  All of the President's movements are explained.
In between there is a lot of background info on Islamic terrorism, Bin Laden, and the planning of the 9/11 attacks.  It ends with the Commission's recommendations.
I recommend everyone read it.  It is worthwhile.
