Thanks. I've ordered this issue so I'll fill in more later when I receive it. Apparently there's a design in there for a Mach 25 spaceplane which sounds interesting.
When did the X-15 fly Mach 25?
Are you saying it wasn't a "space plane"?

Scott ManleyPublished on Apr 4, 2019At Palmdale Airport they have a display of a SR-71 and an A-12 next to each other, as well as a D-21 Drone and a U-2. This is the only place I know that has both aircraft next to each other, making the small differences much more obvious. The A-12 predates the SR-71 and wasn't made public until 1981, long after it stopped flying.* Actual speeds and flight ceiling are classified, so, maybe the SR-71 can go higher and faster but they can't tell us.
A-12 outperformed the SR-71
