Such a great book that is becoming harder to find a decent copy of these days.
There's a great sketch that Kelly Johnson did of the A12. This was in September of 1958(!) and he had a rough top speed of Mach 3.0, with a possibility of Mach 3.2. And it existed on nothing but a sheet of paper and in his mind. No computers with advanced software and super computers with petaflops of power.

First time I've seen that sketch, but it looks like Popular Science lifted it directly for an article from the 80's that I remember distinctly about Project Aurora.
