If you enjoyed this video definitely check out Skunk Works by Ben Rich. He ran the experimental R&D wing that developed the U2, SR-71 and the F-117. It has really interesting information about the development and operation of all these planes. Some of which I was shocked as allowed to be printed.

Second this. Skunk Works by Ben Rich is basically a real life Tom Clancy novel

It was gifted to me by @davidu when I worked for him, and I finally started reading it last night!
