If you like aerospatial history but also if you'll like to know how all this birds were made, you should read "Skunk Works". I have just finished reading it, and is a great book. It tells all the development of the U2, SR71, F117, and more.

It's also greatly recomended for entrepreneurs, they worked as an small team, a very talented and focused group of people building unbeliable planes. At the end it has a great rant against all the bourocracy that has built up alog the years at the government.

Just an amazing read!
