If you find this interesting, then you should definitely check out the book SkunkWorks.

It's about the special projects division in Lockheed who developed the U2 and SR71. One of the interesting things was how they were working on UAV (Unmanned Ariel Vehicles) in the 60's.

It's a thrilling read.

Second this. Ben Rich was a really interesting guy and the first quarter just on the development of Have Blue is a great R&D story.
