Query: The best book on Astronautical Engineering. A scientific jewel.

Finally, now as professor of Fluid Dynamics, I found and bought the book I used to consult and enjoy when I was a student, thirty years ago. With a board including von Braun, Oberth, Dornberger, and so many other brilliant scientists and engineers, the Handbook of Astronautical Engineering is the most complete and concise treaty on the subject I have ever read.
