Excellent find Gariac, I had no idea about that NASA operated one of the YF-12's wired like a pinball machine to develop the comprehensive high mach
analytic tools used by the modern aerospace industry.
That is a really neat variation of the A-12 planform. The folding ventral fin looks similar to the XF8U-3, I wonder if the concepts developed
separately or if there was some sharing of data between the Chance Vought and Lockheed?
