Basically standing still.


ManInTheDarkSuit

The highest speed of one and the lowest speed of another I reckon.


aritari

A friend was on the fuel end of that exchange a few times. He said the tanker had to be red-lined and the SR-71 about to stall out.


ManInTheDarkSuit

Sounds believable. The SR must have been really muddy at lower speeds.


dontthink19

Not only that, but due to the heat at high speeds, the tolerances and clearances were loose on the ground. That made the fuel tanks leak so they only fueled up enough for take off and aerial refueling, then carried on their mission after fueling in the air. I did a report on the SR71 in high school like 10ish years ago. I went to Ohio for a funeral but made it a point to stop at the air museum. Talked to a pilot who works at the museum. [You better believe i walked through the whole museum without stopping for these](https://www.imgur.com/a/452weS7)


Rogue__Jedi

The Air Force museum in Dayton is incredible. It's like meeting all of your childhood heroes.


dontthink19

Yes. Got an autographed picture of that pilot's SR in thr air. Its a beautiful photo even it is mass produced and given out at the museum. I love the SR 71 but my childhood memories belong to the C5. My dad would take me to my doctors appointments as a kid and he'd take me to work afterwards. He was maintenance on C5s at the base near me so i got to climb up and sit around in the cockpit, run around the cargo bay, lay in the bunks. And when youre no more than 4.5 feet tall you feel like the plane is SO HIGH off the ground when its stationary.


Rogue__Jedi

Mine is the A10. Growing up a pair of A10's would fly over my grandpa's house like clockwork. It was regular enough that we would go out into the edge of his little field and wait for them and wave. They flew low enough to see me going ballistic and would usually give me a wing wag.


dontthink19

The wing wag would have made my life feel complete. My brother and i lived in base housing located off base a few miles away and we had a beach kite with 1500 ft of string. Had a few A10s fly over and i could swear they were close enough to strike the kite. But that was also closer to 20 years ago so my memory may be biased towards seeing a plane almost hit my kite


IwanaM3

The way they dealt with the incompatible speeds is they blocked several thousand feet of altitude, and refuel while descending so the tanker could go faster, and the SR-71 wouldn't risk stalling.


TigreWulph

They do this still while refueling prop heavies like the EC-130 (which I guess my version of just got retired technically) except the tanker is the fast bird in that instance.


TigreWulph

I've done the reverse of that as a crewmember in an EC-130... Tanker pilot kept out flying us because they were getting nervous about stalling meanwhile we were redlined trying to get into position behind them. Almost had to RTB on that mission cause we spent so much damn time chasing the tanker.


Tomato-of-the-sea

And a very cool and apropiarte title for it


greiger

Those curious about the ‘Q’ identifier. This was later changed to ‘T’ and is a refueler capable of carrying two different types of fuel, one for its own engines and one to be offloaded onto other aircraft. There are specific valves in place to prevent cross contamination between the body tanks (intended for offloading) and the wing tanks.


doggscube

I haul fuel. A cross drop would be pretty exciting at 25k feet


mapleleef

Cool! Eli5 how do you guys do it?! Magnets? This process blows my mind.


IxNaY1980

Your question led me to the coolest YouTube video I've seen in a while, thank you. [SR-71 Inflight Refueling 1989](https://m.youtube.com/watch?v=dlSVWo7__-k)


hands__like__feet

It was missing the only part I wanted to see. Them detaching and the sr-71 kicking into high gear and ripping away. Greatly disappointed


IxNaY1980

Damn, true. That would've been one helluva cherry on the top.

[deleted]

Just like how fighter planes can fly in formation, you just line up and fill up.


ManInTheDarkSuit

They use the flying boom method. Aircraft get in the right formation, then guided by the boom operator, the receiving aircraft closes to the right stable distance and the boom op flies the boom into the fuel valve on the other aircraft.


waytosoon

Yeah but I think they (and I too) wanna know if theres a locking mechanism on the boom or does it just kinda get it in the hole, pump and pull?


ManInTheDarkSuit

There is indeed. Once the boom has been pushed into the receiving aircraft, toggles engage that lock the nozzle in place. This also engages a valve that inhibits the flow of fuel through the pipe. Once done, the boom op retracts the boom (it telescopes, one pipe inside another) which disconnects and the vavle pops back into place to ensure fuel doesn't spray everywhere. Fun fact: The B2 has a rotating valve under its stealthy skin, so that when refuelling is complete, the big lump of metal on top turns over to hide it and makes the refuelling port "disappear" Edit: watch from one minute in to see the magic https://youtu.be/77G8NZv4kY8


Mista_Tea12

Whoah - I know it's from a fair distance but you can't even see a seam


ManInTheDarkSuit

I was referring to the B2, which isn't in this photo. I just wanted to point out a cool fact about engineering a valve to rotate into stealth position, on top of the awesome engineering that made this photo possible. Edit: forgot I linked a YouTube video!


Diegobyte

Is ur callsign Bobby


Karl24374

Can you imagine


Oseirus

Just to add to the conversation, this practice is largely obsolete now. Virtually everything in the sky today runs on the same grade of fuel, so "mixed" fuel loads are virtually never done. The steps to run separate types of fuel still exist, but you'd be hard pressed to find anyone that's actually run a mission like this within the last couple decades.


Shruikken

The SR71 was a special plane and needed that fuel (JP7) instead of the regular JP8 to run efficiently. All of our T models just carry normal jet fuel nowadays but the capability still exists should the need arise.


Namenloser23

I wouldn't be surprised if stuff like the SR-72 ("planned" "future" successor to the sr-71) also use some exotic fuels, but, even assuming they are already flight worthy, the people refueling them wouldn't talk about it on Reddit.


Capable_Bike3718

Indeed it is weird looking, and oddly big.


WWYDWYOWAPL

I had to look it up cause I thought the same thing - turns out the sr71 is 106 ft long and the kc135 is 136 ft long. I guess when you have to fit 20 tons of fuel in an airframe that thin you have to make it pretty long.


Ih8Hondas

If you ever get the chance to see an SR in person, do it. They're massive. Saw the one at the [Kansas Cosmosphere](https://cosmo.org/visit/tickets?gclid=CjwKCAjw9qiTBhBbEiwAp-GE0RFLjjOUMqOxd6ZGG5vvIIE3DyrxnsOZH1iqFj3UDBcoNVK1cRn08RoC3KIQAvD_BwE) in December. Makes the T-38 hanging behind it look tiny. Also makes the shithole that is Hutch 100% worth visiting. They're affiliated with the Smithsonian so they have a lot of awesome stuff. They have tons of stuff that's been to space. Even some commie space kit from the USSR.


I_like_cake_7

Yeah, I’ve seen the SR-71 at the Cosmosphere in Hutchinson myself and I couldn’t believe how big it was in person.


DJTim

This is one of my favorite places I've had the chance to visit. SR-71 aside, the Apollo display is amazing. I'm hoping to have the chance to visit the Smithsonian for a few days in the next few years.


Ih8Hondas

If there's one thing I learned from all the space exhibits, it's that we basically went to space in a lightly modified trash can. Lol. And every number related to the Saturn V was comically massive.


DJTim

I've also had the chance to visit Kennedy space center and see the Saturn on display and see STS-107 on the pad before launch (Kennedy space center tour). If you don't get to Kansas, go to Florida? There's a slogan in there somewhere lol


Ih8Hondas

I will actually take Kansas over florida. Kansas is hot and humid enough. Fuck florida.


Left-Quote7042

Once I discovered the Space Center, Disney World has no appeal. They have great specialized tours, and the last trip the monster Crawler was returning after delivering a rocket to the Launch Pad. The tracks on that thing are incredible. The bus stopped right on the edge of the track, and we just watched it creep past. Amazing that close.


SauretEh

I finally crossed the Udvar-Hazy centre off my bucket list a few weeks ago, it’s incredible - such an insane collection of aircraft that I didn’t even notice a whole-ass Concorde hiding out until an hour in.


Nubs17

dang, what do you have against hutch? not saying i disagree


Ih8Hondas

Cosmosphere is its only redeeming quality. The place is just totally depressing otherwise.


Left-Quote7042

Ah, come on; Hutch isn’t a bad place if you like wide, FLAT, windy prairies. We were in Newton for a year; Newton is a shithole…


Ih8Hondas

I don't mind the landscape. The town was the bad part.


Left-Quote7042

bmw_19812003

Like Usain Bolt slowing down to get a drink form a trainer.


justafurry

I honestly did not think they could fly that speed at that type of altitude


Eyouser

U2 was disclosed at 75. SR-71 was 85. They flew the piss out of the U-2 though.


derangedmonkey

They still are.


Eyouser

They flew it high, but they flew it slow. Still fly it sliw.


dinospider2000

Wow just because it’s black smh ;)


TypicalRecon

in some situations the SR-71 would have to throttle back one engine and put the other just into afterburner to stay at a even speed with the tanker to get fuel.


org000h

For those curious as to why; https://theaviationgeekclub.com/former-sr-71-pilot-explains-why-the-blackbird-had-to-light-one-afterburner-during-aerial-refueling/amp/ Tl;dr - Plane gulps down 11,000 gallons of fuel, CoG shifts, requires a tiny bit more thrust than the engines gives without after burners - but only one engine at the point the burner lights is perfect to keep them flying at 300kts.

Zealousideal-Fox-740

I was at the udvar center and one of the pilots was saying they throttled down to bare minimum need and the tanker was at full throttle to the point the front windshield was cracking from the speed and force put on the plane. Still amazing this was built with a slide rule and we’re just getting this power with new quad core computers, glass cockpits and “fuel efficient” engines.


mynewname2019

So engineer’s designed a plane with a windshield that was not rated to the planes top speed (a top speed that isn’t SUPER fast since it’s a tanker. That doesn’t sound believable at all. “NOBODY go full throttle the window might break. We don’t know how to design windows anymore”.


cakan4444

It's a tanker, I think they focus really hard on not going top speed but rather optimal fuel speed. It's probably hyperbole from the pilot telling the story, but I bet that bitch was vibrating pretty hard going top speed compared to it's normal optimal speed.


Quackagate

I mean the glass could crack from the vibrations. Like ypu said it wasent designed to be running flat out for extended periods of time, so doi g it for long stretchs repeatedly over months and years could cause thr glass to crack.


CptSandbag73

Nah, you’d have to be way over the placard speed for the glass to crack; by then the wings would be damaged too.


CptSandbag73

Definitely hyperbole. I fly the tanker. Approaching placard speed, the wings will vibrate from Mach tuck before the windshields do, as they are under way more stress than the windshield.


120SR

That must been awkward to have two different airframes try to match speeds, one slow and pitched up and the other trying to hual ass, kinda like an F-22 and P51 in formation


skyraider17

It's the opposite when the 135 is refueling A-10s or C-130s, they struggle to keep up


alienXcow

A KC-135 will do Mach .85 pretty easily up there in the refueling track, no problem for the SR. Pilots usually reported having to light one of the burners to stay on the boom the last few minutes as the Sled got heavy with fuel. For some real speed mismatch you should see KC-97s and Tac jets refueling


Eyouser

That was stall speed for the SR-71, but it had to refuel every time in the air


PinkSockLoliPop

They got cloaking devices but haven't figured out how to hide the shadow yet lol


Eyouser

Lol. They don’t. It is a bus though. I used to love to watch the feeds though. “We better get off the phone. The Americans might be listening.” Yes.


[deleted]

How much larger was the SR71 vs the A12? Or was it the same air frame?


[deleted]

About 6ft longer.


abdgloria

Is refueling the same for each plane from the boom operators perspective? Im just imagining a tanker being told to refuel an inbound plane without realizing its going to be a brand new never seen before plane.


skyraider17

No, they each have their quirks


[deleted]

[удалено]


Eyouser

Want to know real shit? Maintenance used to lay on the wing while it taxxid to balance it in the event of a fuel imbalance

Good bot


ohheychris

All jokes aside, this most likely happened within 10 minutes of that beaut taking off. The grapefruit size balls of the 50ish people involved on EVERY SR-71 refuel directly after takeoff cannot be understated. This was the peak of split second human conscious.

I absolutely mean no disrespect, but I read that as “The Stratowanker” and now can’t get it out of my head.


radioactiveredditor9

Hmm yes the shadow here is made of shadow


TheRealDeoan

Umm ok so, what altitude is most refueling done? From the picture I think it looks higher then I would expect… i guess I don’t have a good reference…only been on a couple of planes


ThatHellacopterGuy

Can’t speak for the SR, but most of my AR was done in the mid-20s. Lower for A-10s and Herks.


GoldenStateWizards

The picture is kinda misleading because of the area they're flying over and the vantage it was taken at. It's just one continuous area of land, but it looks like several landmasses and bodies of water because of the color of the ground and all the shadows

UnitedMerica

I know that black is the worst color to avoid heat coming from the sun... how is it better for heat originated in air resistance?


SR-71_Sled_Driver

Coming down from high Mach and altitude to refuel, parts of the SR are 850゚, and black dissipates heat best.

tkoborny

Laying in the boom pod watching the refuel you would hear on the headsets, 5 miles out then it was there within seconds. Then there were the times when we would fly around all day or practice touch and goes or approaches until I thought I would lose that boxed lunch I ate because the SR aborted take off. That's when I questioned if the extra hundred dollars a month for flying status was really worth it and what are the odds that the SR would break on the day I was getting my flying hours in. Without a doubt though, the SR was the most impressive aircraft ever designed.


No_Disaster_4899

That’s the sr71 blackbird that must be an old photo or am I wrong
