This is as advertised - so if you are looking for insights into the Lockheed Skunkworks as it was this is a great introduction. A long time ago I had a previous book by Ben Rich which as I recall had a lot more anecdotal stories about the F117A. I lent it someone and it was never returned so I thought maybe this was an updated version. This book covers a lot more about the U2 and the SR 71 but at lot less about the F117.
I (mostly) enjoyed the extra quips from insiders and outsiders, it served to fill in a little more detail.
