NASA mysteriously trying to pull world’s fastest plane, SR-71 Blackbird, out of retirement — and won’t say why (nypost.com)

Seeing Blackbird fly again after all these years would be incredible. I'd love to know what NASA has planned for it.

NASA is researching quieter supersonic flight, and I can't help but think of how the (also Lockheed Martin) X-59-

Loooong boi

-has a extreme wing profile/nose, not unlike SR-71:

Almost as long

8700 lbs max doesn’t seem like a lot, are they counting on the parabola for most of the acceleration I wonder?

Its not very big. 8700 lb of fuel is 25% of its MGDW, which seems pretty normal to me?

I think the most likely explanation is something like this, they want data they can't otherwise get.

Machine learning + fluid dynamics?

Turbulence at the trans-sonic barrier is one of the most difficult and poorly understood problems in modeling even today - Heisenberg famously said he'd ask god two questions: why relativity, and why turbulence? - and as a result experimental results really are the best way of determining even the base parameters of the behavior of a system under those conditions.
