I'll be picking up this book probably this weekend, as I just found out from my father that my grandfather is mentioned several times in this book when he was the Army liason to the Bureau of Naval Weapons, responsible for the specifications that led to the Bell Huey helicopter. He emailed me a couple of pages, and it looks to be a pretty good read.
