Mysterious X-Plane from NASA

It would make sense to use existing, proven systems on such a machine and when it comes to high-speed aircraft, you need to be able to stop. So re-use of the SR-71's undercarriage, or components of it would be understandable.

Bob225 - I agree with your sentiment on these multi-post threads (TL;DR) but I think I mentioned on another thread that we had our stab at all this speculation in the 1990s (I assume you were around then), so why not let the new 6th generation black aircraft chasers have their AI/not AI fun?

I use the 'Ignore' function.

Hi Chris,

Good point, yep i was around in the 80's & 90's getting excited by the EAP, B2, F117 etc.

Lived not far from Mildenhall & Lakenheath at time, so saw the SR-71 fairly often, and saw the F-117's arrive at Lakenheath for the first time.

Ignore is fast becoming my good friend, perhaps it's just my age? certainly turning into a grumpy (er) middle aged man.

That's McNamara levels of petty-spite, he should've been dismissed as SecAF for pulling that stunt and perhaps spend a nice "Vacation" in the Big House.

My guess is this is the rumored hypersonic aircraft LM has been working on for a while now and the SR-71 is being refurbished to act as the highest speed chase plane available. It won't be able to chase for the full envelope, most chase planes can't, but I'll bet the SR-71 can chase for somewhere between 60% to 75% of the new vehicles' flight envelope.
 
I don't want to sound ignorant or foolish... but could this have something to do with a certain aircraft that was rumored to exist in the 90s—one that is soon to be declassified and handed over to NASA for research?

This is probably the most plausible theory I've yet seen for this SR-71 "disappearance". Its mental to think that the SR-71, as far as manned, high speed flight goes, is still state-of-the-art.

Another thought; I wonder what the maintenance cost per flight hour would be now? It was something like $80k per hour in the 80s.....

Easily 200k an hour, just from inflation alone.

Then digging all the old Habu Brats out of retirement to work on the thing.

There was a rumour a couple of years back the pratt and Whitney were buying j58s from museums

IIRC, the engines were not loaded with long-term-storage preservative oils, so while the blades may not be destroyed the internals are.

Not sure about anyone else, but I definitely never even considered “F-14s and SR-71s flying again” for spots on my 2026 BINGO card. Now it’s looking like a person can bring the possibility up in conversation and not be laughed out of the room.
 
Perhaps Isaacman has found the aircraft once spotted over the North Sea in a hanger and fancies flying it.
