Just a couple of things to consider...
1. It is possible that the Pentagon ordered Flight 93 to be shot down and it could very well have been. People reported seeing the plane come down in fiery chunks. If they ever acknowledge this, "Let's Roll!" is going to become as trite as "Where's the beef?" and you'll want to hide this book in the closet somewhere.2. Look who's on the cover of the book. Hey it's not Todd Beamer. It's, hey, it's Lisa! Do you think she's trying to cash in on what presumably happened on 9-11?Nyah. ;-)
