Doc Edwards' book:
Upon Snowmman's advice, I read a fair amount of DB Cooper and Flight 305: Reexamining the Hijacking and Disappearance at the Amazon site.
It's an uneven book in a lot of ways. To start, he describes the skyjacking in the present tense. I found that jarring. Also, he makes many conditional statements such as, "Cooper probably did this," or "we assume he might have done that...," and I feel those passages should have been tightened up by more research.
But he has done a lot of research, and his book will be a well-regarded addition to the Cooper literature. E.G.: He includes a very substantive appendix that annotates all of the transcripts. As someone who has written a book on Cooper, I found Edwards' book to be a strange juxtaposition of information. Reading it was like delving into a subject I knew a little bit about, but not much, because his book is filled with information from people who either refused or were very resistant to talking with me, such as the WSHM, or whom I felt didn't have much to add, like RMB. From that vantage point, it is not surprising that I am not mentioned once, nor is the Mountain News cited as a source of material. Along those lines, I didn't see one mention of this Forum, nor is it cited in the Index. Reflecting upon that dynamic, it is not surprising that Doc Edwards is not a regular participant in our conversations here. However, R99 is cited as a key figure in the editing and composing of the book. For me, it's like meeting someone who says they know all about the Cooper Vortex, and yet, I have never seen them fly by.
Hence DBC and 305 is a strange but worthy book.
