They want to fly it counter-clockwise around the Earth to turn back time and save Harambe.

On one hand, this news is really fucking cool!
On the other, the motivation for this is guaranteed to be really fucking dumb!
There could be some legitimate uses (NASA operates U-2 spy planes over wildfires to this day) but it would not surprise me at all if it is for some dumb reason.
I'm really hoping it's NASA doing some really cool science shit, otherwise you'd expect a military organisation to be doing this.
They're conducting on-going research into aircraft designs that can go supersonic without producing a sonic boom (the thing that made supersonic jets impractical for cross-country flights along with the insane about of fuel they burn) so I'd guess they need a reliable supersonic jet to test against.
NASA probably has lots of data on the SR71 so it makes sense to use that to test new concepts on.
I like its lines, but realistically, I don't know what you'd use it for unless you need extremely high-resolution images.
We know, from Trump's probably-ill-advised tweet back in 2019, that we can do 10-centimeter resolution from reconaissance satellites like USA-224, near the physical limitations of light resolution.
https://en.wikipedia.org/wiki/USA-224
Perigee altitude: 270 kilometers (170 mi)[1]
Apogee altitude: 986 kilometers (613 mi)[1]
https://en.wikipedia.org/wiki/Lockheed_SR-71_Blackbird
During missions, the SR-71 operated at high speeds and altitudes (Mach 3.2 at 85,000 ft or 26,000 m)
The SR-71 operates at a tenth to a thirtieth USA-224's altitude, so assuming comparable imaging systems (which I could believe) and that there aren't stability or thermal issues (which I'd be less-certain of) it can get ten to thirty times the resolution of a KH11 satellite from the lower altitude. I'm not sure how much utility there is in reconnaissance to getting 1 cm or ⅓ cm resolution images instead of 10 cm.
I can think of a couple of reasons to use the SR-71 again.
- Concern that a crash in space could lead to a cascade of crashes, disabling all sattellites.
- (On demand) capacity. I could imagine that the SR-71 can cover an unplanned spot faster than sattellites. Also, with the wars in Ukraine and Iran they're maybe finding out that they don't have enough imaging capacity.
- The imaging angle, a plane can image almost horizontally, they can look under bridges, through windows etc.
- A ten times increased resolution could be useful for recognizing details, maybe it's even good enough to recognize people though it might be pushing the limits of facial recognition. It's also the kind of resolution where they can read some text, e.g. identifyers on shipping containers or military vehicles.
the sr-71 is definitely not a scramble-able plane:
- it leaks fuel when on the ground (it shrinks when cold) so it's stored empty,
- it's as aerodynamic as a brick when subsonic so it needs an insanely long runway, and
- it has an always-on afterburner so it burns an alarming amount of fuel.
when they were doing surveys of iraq during desert storm they had to field a fleet of eight tanker planes over the indian ocean just so the damn thing would make it from japan to the gulf.
Edit: oh and those are specially designed tanker planes because of course it uses JP-7 so they needed separate tanks for that and their own fuel. they also needed to be able to refuel at like 850km/h or the blackbird would just drop out of the sky.
love that plane.
Iirc it starts nearly empty and is only fueled up in the air, so basically no way around tanker planes.
that's apparently not true, it would take off with half fuel because the landing gear could buckle under the full weight.
even with a full tank it could only go for about 90 minutes though so anything nontrivial did indeed require a tanker.
still faster than launching a new satellite
Can't they do all that with drones?
You need to deliver the drones to the location of interest though. And regularly bring fresh ones I guess. A stealthy and fast as fuck delivery platform would make sense.
I don't think the SR-71 has much cargo space if that's what you're suggesting.
realistically, I don't know what you'd use it for unless you need extremely high-resolution images.
Well, what does NASA do?
I think it's a pretty safe bet that NASA wants it to test something about aerodynamics at extremely high speeds. Perhaps they want it to deploy some experiment at mach 3. Sometimes you just don't know if your simulation models are correct, and you need to try something in the real world.
I suppose it's also possible they want it to get some close up footage of a rocket during launch or reentry.
But I think the most likely answer is still that they just need something that goes very fast.
The thing is sounding rockets do exactly that and are still in service (vs somehow unfucking an ancient plane that hasn't been serviced in decades with tooling that no longer exists) and there are multiple companies out there operating supersonic drones for high speed tests of whatever you wanna do.
I dont see the value in bringing the blackbird back into service. I think its more likely that they want to freshen up the paint and park it at some press conference / event.
Well, you can control your airspeed and attitude in an airplane, solid rockets just make a ballistic arch and they only accelerate, they can't maintain a speed.
So if you want to test how air behaves in a particular regime, you can't actually maintain that regime with a sounding rocket, so the best you can get is a snapshot.
Honestly, if what they're working on is dialing-in their computer models, the more precise data they can get, the better. It makes sense to maintain a speed for a minute, so you can get a really good running average on your measurements of air pressure, heating, drag, etc. They may want to conduct the same tests at different altitudes and airspeeds, and probably all in level flight. To control all those factors, that's near impossible to do with a rocket.
Again, I don't know what they're doing, what their actual plans are. I'm just saying there are absolutely plausible reasons to use this aircraft.
Satellites are too predictable, plus too infrequent. If there are two spy satellites that cover Iran, for example, Iran can easily know when and what direction, then presumably take some effort to cover whatever they want to hide.
A reconnaissance plane can show up without warning, any time, loiter for at least minutes, take pictures from different angles, in addition to sharper imaging. We can speculate they may also have sharper non-optical imaging, such as thermal or radar
Ok, but what if there are several satellites that cover iran at all times? What if they would need to hide from most directions all of the time? Because I think that's basically the situation right now. The whole world is being monitored from multiple angles all of the time by several different governments. At that point, reconnaissance aircraft in general seem a little redundant.
I think the only real utility they offer is the ability to swap out sensors between flights and upgrade old cameras to the new cutting edge options whenever they're available.
My money's on hegseth wants the sonic booms when he's giving a speech about how manly the army is. Considering they have that unmanned x-37B for spy satellite stuff, and it would be a massive amount of money to bring back the blackbird, while NASA is having its budget cut, it is 100% going to be for some self serving promotion.
NASA flies U-2 spy planes over wildfires. They might be able to do the same thing with the SR-71. I really don't know, that's my best guess for a realistic use case.
I would just like to point out that while not confirmed, it has been speculated since the mid-2000s that the actual imaging resolution of the satellites is closer to 2mm. Or as the joke goes, we'll figure out what brand of cigarettes you smoke by reading the filter.
I would say that that's purely speculation. Physics won't allow it. The diffraction limit basically limits the best resolution to about 10 cm (assuming an altitude of 200 km, blue light and a humongously large lens with a diameter of 1 m). It's likely that they're quite close to the diffraction limit and maybe they have even more extreme hardware than I would guess, but a two orders of magnitude better resolution isn't happening anytime soon I think.
They decided that the classic speed check story needs an update after all these years.
There were a lot of things we couldn't do in an SR-71, but we were the fastest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the jet. Fun would not be the first word I would use to describe flying this plane. Intense, maybe. Even cerebral. But there was one day in our Sled experience when we would have to say that it was pure fun to be the fastest guys out there, at least for a moment.
It occurred when Walt and I were flying our final training sortie. We needed 100 hours in the jet to complete our training and attain Mission Ready status. Somewhere over Colorado we had passed the century mark. We had made the turn in Arizona and the jet was performing flawlessly. My gauges were wired in the front seat and we were starting to feel pretty good about ourselves, not only because we would soon be flying real missions but because we had gained a great deal of confidence in the plane in the past ten months. Ripping across the barren deserts 80,000 feet below us, I could already see the coast of California from the Arizona border. I was, finally, after many humbling months of simulators and study, ahead of the jet. I was beginning to feel a bit sorry for Walter in the back seat. There he was, with no really good view of the incredible sights before us, tasked with monitoring four different radios. This was good practice for him for when we began flying real missions, when a priority transmission from headquarters could be vital. It had been difficult, too, for me to relinquish control of the radios, as during my entire flying career I had controlled my own transmissions. But it was part of the division of duties in this plane and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. Walt was so good at many things, but he couldn't match my expertise at sounding smooth on the radios, a skill that had been honed sharply with years in fighter squadrons where the slightest radio miscue was grounds for beheading. He understood that and allowed me that luxury.
Just to get a sense of what Walt had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Los Angeles Center, far below us, controlling daily traffic in their sector. While they had us on their scope (albeit briefly), we were in uncontrolled airspace and normally would not talk to them unless we needed to descend into their airspace. We listened as the shaky voice of a lone Cessna pilot asked Center for a readout of his ground speed. Center replied: "November Charlie 175, I'm showing you at ninety knots on the ground."
Now the thing to understand about Center controllers, was that whether they were talking to a rookie pilot in a Cessna, or to Air Force One, they always spoke in the exact same, calm, deep, professional, tone that made one feel important. I referred to it as the " Houston Center voice." I have always felt that after years of seeing documentaries on this country's space program and listening to the calm and distinct voice of the Houston controllers, that all other controllers since then wanted to sound like that, and that they basically did. And it didn't matter what sector of the country we would be flying in, it always seemed like the same guy was talking. Over the years that tone of voice had become somewhat of a comforting sound to pilots everywhere. Conversely, over the years, pilots always wanted to ensure that, when transmitting, they sounded like Chuck Yeager, or at least like John Wayne. Better to die than sound bad on the radios.
Just moments after the Cessna's inquiry, a Twin Beech piped up on frequency, in a rather superior tone, asking for his ground speed. "I have you at one hundred and twenty-five knots of ground speed." Boy, I thought, the Beechcraft really must think he is dazzling his Cessna brethren. Then out of the blue, a navy F-18 pilot out of NAS Lemoore came up on frequency. You knew right away it was a Navy jock because he sounded very cool on the radios. "Center, Dusty 52 ground speed check". Before Center could reply, I'm thinking to myself, hey, Dusty 52 has a ground speed indicator in that million-dollar cockpit, so why is he asking Center for a readout? Then I got it, ol' Dusty here is making sure that every bug smasher from Mount Whitney to the Mojave knows what true speed is. He's the fastest dude in the valley today, and he just wants everyone to know how much fun he is having in his new Hornet. And the reply, always with that same, calm, voice, with more distinct alliteration than emotion: "Dusty 52, Center, we have you at 620 on the ground."
And I thought to myself, is this a ripe situation, or what? As my hand instinctively reached for the mic button, I had to remind myself that Walt was in control of the radios. Still, I thought, it must be done - in mere seconds we'll be out of the sector and the opportunity will be lost. That Hornet must die, and die now. I thought about all of our Sim training and how important it was that we developed well as a crew and knew that to jump in on the radios now would destroy the integrity of all that we had worked toward becoming. I was torn.
Somewhere, 13 miles above Arizona, there was a pilot screaming inside his space helmet. Then, I heard it. The click of the mic button from the back seat. That was the very moment that I knew Walter and I had become a crew. Very professionally, and with no emotion, Walter spoke: "Los Angeles Center, Aspen 20, can you give us a ground speed check?" There was no hesitation, and the replay came as if was an everyday request. "Aspen 20, I show you at one thousand eight hundred and forty-two knots, across the ground."
I think it was the forty-two knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that Walt and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most fighter-pilot-like voice: "Ah, Center, much thanks, we're showing closer to nineteen hundred on the money."
For a moment Walter was a god. And we finally heard a little crack in the armor of the Houston Center voice, when L.A.came back with, "Roger that Aspen, Your equipment is probably more accurate than ours. You boys have a good one." It all had lasted for just moments, but in that short, memorable sprint across the southwest, the Navy had been flamed, all mortal airplanes on freq were forced to bow before the King of Speed, and more importantly, Walter and I had crossed the threshold of being a crew. A fine day's work. We never heard another transmission on that frequency all the way to the coast. For just one day, it truly was fun being the fastest guys out there.
As told by:
Major Brian Shul, USAF Retired
The Cessna pilot: "All those guys did this because of what I did!" :)
I'll stop and read this, every time.
Same. Which is why I didn't mind finding it.
I think there's part of every nerd that loves seeing a real expert casually embarrass some cocky hotshot.
Thanks for taking the time. I must have read that five times before but it's such a great story I'll always take the time.
I saw Shul (and Walter too) speak at an event near my house shortly before he died. He closed with this story, which if I'm honest I'm sure 90% of the crowd was there to hear. It was like the Beatles playing Hey Jude or something.

Sled Driver is a great book also if you're into that sort of thing.
It's a famously difficult (or at least expensive) book to find in person. I have a PDF copy of it.
Several years ago I met a U-2 pilot, and naturally we talked about the SR-71. I mentioned I had a PDF copy of Sled Driver. His eyes lit up and said he'd been looking for at least a digital copy forever. I sent him the PDF, and in thanks he invited me to the base and showed me all around the U-2 stuff; the vacuum chamber, the room in which they suited up, the planes on the ground, and most impressively took me in the chase car for a U-2 that was practicing touch-and-gos.
We already got that update:
There were a lot of things we couldn't do in an Cessna 172, but we were some of the slowest guys on the block and loved reminding our fellow aviators of this fact. People often asked us if, because of this fact, it was fun to fly the 172. Fun would not be the first word I would use to describe flying this plane. Mundane, maybe. Even boring at times. But there was one day in our Cessna experience when we would have to say that it was pure fun to be some of the slowest guys out there, at least for a moment.
It occurred when my CFI and I were flying a training flight. We needed 40 hours in the plane to complete my training and attain PPL status. Somewhere over Colorado we had passed the 40 hour mark. We had made the turn back towards our home airport in a radius of a mile or two and the plane was performing flawlessly. My gauges were wired in the left seat and we were starting to feel pretty good about ourselves, not only because I would soon be flying as a true pilot, but because we had gained a great deal of confidence in the plane in the past ten months. Bumbling across the mountains 3,500 feet below us, I could only see the about 8 miles across the ground. I was, finally, after many humbling months of training and study, ahead of the plane.
I was beginning to feel a bit sorry for my CFI in the right seat. There he was, with nothing to do except watch me and monitor two different radios. This wasn't really good practice for him at all. He'd been doing it for years. It had been difficult for me to relinquish control of the radios, as during my this part of my flying career, I could handle it on my own. But it was part of the division of duties on this flight and I had adjusted to it. I still insisted on talking on the radio while we were on the ground, however. My CFI was so good at many things, but he couldn't match my expertise at sounding awkward on the radios, a skill that had been roughly sharpened with years of listening to LiveATC.com where the slightest radio miscue was a daily occurrence. He understood that and allowed me that luxury.
Just to get a sense of what my CFI had to contend with, I pulled the radio toggle switches and monitored the frequencies along with him. The predominant radio chatter was from Denver Center, not far below us, controlling daily traffic in our sector. While they had us on their scope (for a good while, I might add), we were in uncontrolled airspace and normally would not talk to them unless we needed to ascend into their airspace.

You knew right away it was a Twin Beech driver because he sounded very cool on the radios. "Center, Beechcraft 173-Delta-Charlie ground speed check". Before Center could reply, I'm thinking to myself, hey, that Beech probably has a ground speed indicator in that multi-thousand-dollar cockpit, so why is he asking Center for a readout? Then I got it, ol' Delta-Charlie here is making sure that every military jock from Mount Whitney to the Mojave knows what true speed is.

I was torn.
Somewhere, half a mile above Colorado, there was a pilot screaming inside his head. Then, I heard it. The click of the mic button from the right seat. That was the very moment that I knew my CFI and I had become a lifelong friends. Very professionally, and with no emotion, my CFI spoke: "Denver Center, Cessna 56-November-Sierra, can you give us a ground speed check?" There was no hesitation, and the replay came as if was an everyday request. "Cessna 56-November-Sierra, I show you at 76 knots, across the ground."
I think it was the six knots that I liked the best, so accurate and proud was Center to deliver that information without hesitation, and you just knew he was smiling. But the precise point at which I knew that my CFI and I were going to be really good friends for a long time was when he keyed the mic once again to say, in his most CFI-like voice: "Ah, Center, much thanks, we're showing closer to 72 on the money."
For a moment my CFI was a god. And we finally heard a little crack in the armor of the Houston Center voice, when Denver came back with, "Roger that November-Sierra, your E6B is probably more accurate than our state-of-the-art radar. You boys have a good one."
It all had lasted for just moments, but in that short, memorable stroll across the west, the Navy had been owned, all mortal airplanes on freq were forced to bow before the King of Slow, and more importantly, my CFI and I had crossed the threshold of being BFFs. A fine day's work. We never heard another transmission on that frequency all the way to our home airport.
For just one day, it truly was fun being the slowest guys out there.

It's either clickbait or bullshit.
I agree with the skepticism, however this one is being reported by real aviation news sites, Aviation Weekly specifically.
The confirmed news is an SR71 that used to be parked outdoors has been moved.
Investigative journalism and some theorizing goes further, I found The Aviationist article saying "according to Trimble’s reporting, NASA also contacted former members of the SR-71 program to determine whether they would be interested to participate in a potential return-to-flight effort."
Hey, at least it's not paywalled.
NASA is researching quieter supersonic flight, and I can't help but think of how the (also Lockheed Martin) X-59-
![]()
-has a extreme wing profile/nose, not unlike SR-71:
8700 lbs max doesn’t seem like a lot, are they counting on the parabola for most of the acceleration I wonder?
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.
Probably because the Pedo-in-Chief saw it in a movie. I swear that's how he gets some of his stupid fucking ideas-- like the reopening of Alcatraz. You can't tell me that moron didn't just finish watching The Rock (nic Cage movie) when he decided that.
Well, Mayday did just come out in September, and that features an SR-71 ish spyplane
Next up: A base in the bermuda triangle
A prison for monsters, run by Amelia Earhart.
Never heard the Alcatraz one!
Just visited San Francisco for the first time a few weeks ago, and Alcatraz was dope. Thought it's always been open to the public.
The fun way to watch that movie is from the perspective that it's really a bond movie that doesn't focus on Connery
His racist sidekick Musk was also obsessed enough to name one of his weird brood after that plane too.
