What interested me about Chapman was, relatively speaking, he seemed like a down to earth normal guy. He had a job in an exciting career field, but had a mundane go of it, again relatively speaking. Until he was ultimately tested, and passed beyond what one can comprehend. These are the kind of stories kids should learn about in school. Chapman is an example for all.
Dan Schilling and Matt Eversman wrote a book about Blackhawk Down, detailing accounts from various participants. It's a good read as well.
