barnes & noble, because this is my hometown bookstore. i'm usually browsing for books. i want to thank susie and dave and kim for making this possible and also for c-span2 and booktv for covering. we will do a q&a afterwards. i'm going to start with a question for myself, if that's okay, which is concern i get a lot -- why would a sports guy write a book about flight 93. it's because no one else did, and apparently no one was going to for a while, and i thought the story needed to be told. i'm a history buff, and i go to gettysburg all the time. i had been out to the temporary memorial ten times, maybe more than that. it's only 90 miles from pittsburgh where the flight crashed, and i wanted to read more and learn more and was frustrated that i couldn't do it. there's amazingly little amounted about flight 93. there was one book written less than a year after the crash. the author did a great job, but there just wasn't much known back then, and in all the time since then, so much more has come out. and i just thought the story deserved a narrative, a full narrative from beginning to end. not just the flight.
