I was 18 stationed at Beale AFB as a Avionics Instrument Tech back in 1982. I fixed all the instruments and did the "spike schedule" on the SR-71. The spikes could move 26 inches and the fwd and aft doors would open and close at different speeds and turns. We checked the system up to 85,000 ft and topped out at 3.2 mach on the spike cart(test equipment). Each SR-71 sortie had a formal debrief with the tech reps and the mechanics. For my shop we were interested in aerodynamic disturbances or engine stalls which usually occurred when the inlet spike and or doors were out of calibration for the speed, altitude, or AOA. We had recorded MRS tapes. This was like a EKG line across a paper. The altitude topped at 85,000 feet and the speed stopped recording at 3.2 mach. I saw many tapes of 3.2 mach. The Lockheed engineers never disclosed what the absolute top speed was they did say it was limited by the spike and the fwd and aft doors. I am 60 now and I am blessed to say I wrenched on the SR-71 for the first years of my AF career. This was a awesome video, thanks for bringing back memories. God Bless 🙏

What the doors adjusted how opened and closed they were during different maneuvers? I was not aware of that I just thought they opened when they were using the engine as a ramjet for thrust as opposed to when they were using the turbines for thrust. I didn't know that the doors actually fluctuated depending on what they were doing

In the 70's the declassified top speed was over Mach 3.2. Flip those numbers and you get Mach 2.3. To which I have a question for you: What two U.S. acft, both fighters in operation today, can attain a nearly identical Mach 3.2 top speed, and perhaps greater?

One of my grandfathers was a SR-71 crew chief. He told me, back in the 90s when it was being "decommissioned", that the top speed would never be disclosed because the Airforce didn't know for sure what it was and would probably never know. So the following might be the truth or just a cool story. You mentioned the manual saying the speed was more limited by the structural integrity of the airframe and air inlet more than the engines, this is true but an SR-71 that had been flying for awhile was faster than one brand new. He said that each plane had become an unique individual with slight differences in length, width and shape, and that each time they pushed that mach 3.2+ they changed a little more. The skin, frame and air inlets were being slightly alterened, reforged, by air pressure and friction heating making them "organically" reshaped to be just slightly more aerodynamic and more efficient each time, when they didn't break themselves or pieces fuse together that shouldn't. He never said how they measured these differences but that they were small, not noticeable to the eye between individual flights, but made things difficult to repair any worn or damaged surface segments with stock parts. He said that this was first noticed back in the late 60s and Lockheed was very interested in how each plane changed, he believed that the planes retired in the 90s were probably different in shape and significantly faster than when he worked on the same ones in the 60s. I have no way of verifying anything he said he was talking around NDAs and national secrets and would not give specifics for a variety of reasons, so might be true might just be a cool story.

This doesn't line up with the reality of what limits the top speed of that plane. It's not thrust or drag limited, it's safety limited. The engines had plenty of thrust to accelerate it well past its top speed, but doing so would cause them to melt. There's nothing about the shape of the aircraft or the engine intakes that could change the temperature of the intake air.
@yamahakid450f5 ай бұрын
@toby1248 Something like water methanol injection could most definitely cool the air in the intake....since heat is the biggest killer of a diesel, i use a 2 nozzle spray in my diesels charge pipe before the air enters the cylinders...it atomizes before entering the cylinders and only provides a cold air, it doesn't actually burn or cause cylinder wash. So I'm sure they could use something to cool the air enough to allow more power out of it, atleast to a certain point...what that would be or how much you'd need to continue cooling the air, I have zero clue...getting enough of it on board to keep it fed may be the issue with that idea, I'm sure it sucks the fuel down, so therfore water/meth mix.

Two stories about the SR-71: 1 - I met a guy that told me he worked on the engines for the SR-71. What he said was that the turbine blades were encased in a ring of graphite. The blades went so fast that they stretched and ate into the graphite to maintain the seal. This whole system had to be replaced after every flight. 2 - I also met a guy that was stationed at the Plattsburgh AFB and told me he saw an SR-71 cross his radar screen once. There were just two blips before it exited his screen.

I worked in the J-58 overhaul section 577 at P&W WPB FL for the last year of production and have seen the insides of them many times....and can say that it's an amazing engine but nothing needs to be replaced after every flight. There ARE thermal limits on various components that if exceeded will shorten their TBO and the only case of something needing replacing after a flight would likely involve a massive pilot error and the guys who flew them were absolute professionals who didn't do things like to their aircraft. For sure it's possible that somewhere sometime somebody pushed one WAY beyond the normal operating conditions which then needed repair before another flight...but that would be an exception rather than the rule I think. Every engine was test run extensively including a 33 minute 'Qualification Run' at full Military Power where fuel flow, thrust and all temperatures and pressures were carefully monitored before the engine was released out to the field. Of course this was at Sea Level and full Afterburner but not involving the compressor bypass tubes that ran straight back to the burner can which were used over Mach 2. The real engineering genius in the Blackbirds was in the inlet ducting where the Mach 3+ airflow slowed down under control to subsonic velocity to be fed to the engine. Information about the ducting and how it worked is well worth a read if you are interested in such things...the guys who designed it were from another world. Anyway....should something internal need replacing the engine would have been sent back to the plant and another installed from their spares in the field. Even working in the overhaul section things were compartmentalized and few people had free run through every system and component. I worked on the afterburners, fuel system and compressor sections and wasn't privvy to the turbine so can't comment on how or if they were sealed. For sure the compressor blades are sealed on the ends as most modern high performance turbines are today. Nothing sounded like a J-58...it's a 'Big Block' motor that doesn't spin real fast like the F-100's and F-119's do so the sound is a deep guttural ROAR that shakes you inside...just glorious and I'm very sad that nobody will ever hear one again.

Yes. A missile launches towards a calculated intercept point, and if the aircraft accelerates, that pushes the intercept point further away because the missile has to fly to the NEW (and constantly moving-further-away, if the acceleration continues) intercept point. So the aircraft doesn't have to actually out-speed the missile; it only has to push the intercept point out-of-range of the missile. That being said, at operational speeds the SR-71 accelerated like a scalded rabbit. It couldn't pull more than about 3 G's in a turn, but its signature move was ACCELERATION. With the engines in ramjet mode, there were no turbines to spool up. More fuel was simply sprayed into the combustion chamber and the acceleration was instantaneous. It would slam the pilots back in their seats like a sports car. The rate at which the SR-71 could accelerate was in that ballpark. So it makes sense that the SR-71 would normally operate significantly BELOW its maximum speed, so that it could ACCELERATE if a missile was launched.

You could see the Sam's falling behind the plane then their proximity fuses blowing the missiles up!

One day, while he and many others were working on those planes in the hangar, an SR-71 developed some kind of problem and had to land at that facility.

This was sometime between 1968 and 1970 when the SR-71 had just started flying and was still super secret. My dad and his fellow co-workers had no idea what was going on, so they went to the break room/lunch room... which had some great big windows gave them a great view of the runways and allowed them to see the SR-71 roll up into the hangar.

Alex -- Check the data on the SR-71 speed run from New York to London. From a reliable source (a KC135Q pilot), that SR took on fuel near the Azores. Time to refuel at the tanker's top speed, subtract that time and corresponding distance from between the timing gates, and recompute the Mach based on remaining distance divided by the remaining elapsed arrival time at the London gate -- not the landing time. It's stunning. . . and may be why NO AIRBREATHING JET has ever attempted to eclipse that record. To quote Kelky Johnson in a public interview I attended in person, ". . . we wish the (then) Soviets would match or break it (the record), because there's still a little left under the hood."

Hi, I'm a former aircraft mechanic for the former (not this new crap, wheels falling off, engine on fire, off the runway UAL) United Airlines and I worked alongside a former in flight refueler for the SR-71. He told a story of how during a refueling operation where he's in visual contact with the pilot, he asked the pilot how fast the "Blackbird" could actually go. He said the pilot responded over the radio with "I can't tell you it's classified.". Then in a remarkable display of "pulling back the curtain" the pilot held up his hand and showed the refueler all five fingers as if to state an actual speed of mach 5! Now here's something people rarely state when mentioning Mach: Mach at altitude, that is, above 30,000ft is 652 mph and at sea level it's 752 mph. This is because mach is a speed of sound measurement which varies with density. In less dense atmosphere mach is slower which is the case at higher altitude. In outer space Mach is zero. These things need mentioning when throwing around Mach numbers. So, with that in mind, Skunk Works may have been playing a little game by publishing low altitude mach Numbers to throw looky-loos off of their trail! Mach 3.2 at sea level is 2,407 mph approx. At altitude it's only 2,087 mph approx. They know that the Russians would have been thinking 3.2 is an "at altitude" speed. If they really mean that the speed is 2,407 mph and the craft actually flies that speed at altitude then it's relevant Mach number is actually 3.69. Now if the 71 flew at mach 5 at attitude like my coworker stated then it would actually achieve a speed of 3,260mph which is very close to what another commenter said here about the plane regularly flying at 3,000mph. That speed's mach number drops to 4.3 at sea level. Back in the early '90's I spoke with an SR-71 pilot at fleet week in San Francisco and he told me the limiting factor of speed wasn't the engines because they are ramjet engines, but it was the limit of the aircraft material capabilities. He said the leading edges would heat up to 900 deg F. Funny though, he didn't say they couldn't get hotter and maintain their temper! He also didn't say what speed or altitude the craft was flying at when they got that hot. It seems to me that they speak to people stating specs in an ambiguous way knowing that we will assume they mean one thing when they didn't actually state it. When I hear stories like this and I look at all of it from the 30,000 foot view it all comes within the realm of possibility! When all is said and done, I really don't know, they're just stories until I can actually verify it all! Peace out!

Also even in the 1960's the Atlas rockets could take the heat generated at 17,000mph which is their entry into orbit speed. I say this because thermal limits are always mentioned about the 71.

I would not question for a second whether the SR-71 is / was Mach 5 capable. The issue really is the fact that the poor bird has to take off. If the airframe was dropped at 30k feet and 300-450 mph, the restrictors which allow its power plant to go dual mode would be lifted and it could likely maintain stability well past five fingers. It's all about compressor stall. For the time, the intake design is an absolute amazing breakthrough. That was how many decades ago? Dual-mode means compromises. Maybe there's a "third mode" setting no one every admitted to already built in. (Likely would have been in the mid 80s.) I'm guessing the last 5 were tested and capable of blowing past at least 3.8 without mods, with a freshly designed 25 years newer inlet system? nothing wrong with the airframe going for more sky.

Back in 1988 I had a girlfriend who was a USAF air traffic controller. She monitored the sea of Japan. She told me that SR-71's often flew across her airspace, but did not show-up on radar. SR-71 pilot's transmitted their position using Morris code. She said it was pretty easy to calculate their speed between position fixes. They crossed her airspace at 3,000 mph. I don't think anyone believes the SR-71 could only fly 500 mph faster then a stripped-down F-15 in full after-burner.

The crew chief of the last SR-71 to retire, was my roommate in a transient barracks in California for three days. He gave me some cool photos of the bay area from the camera on "his" plane...while at 80,000ft. The grain of the pictures is so fine that when you hold up a magnifying glass to it, you can see the faces of the people on that were cruising their boats on the bay that day. He also said that 3.7 minutes was how long it "could take, speaking unofficially of course" to cross from the east coast to the west coast at 80,000+ft in what he called "fast mode", and that his plane had done it. Then he went on to rant a little bit about the PM's (Periodic Maintenance) needed afterwards, and the fact that there was no weekend off because of it.

My father worked space track at Cheyenne Mountain in 1968 during the Vietnam War. After the blackbird was decommissioned he told me a few stories that indicated that the blackbird was both faster than it's official top speed and could fly higher than it's official altitude ceiling. I am certain the pilots were trained fully in the capabilities of the aircraft and never reveal it's true capabilities. You have to remember that the aircraft was designed in the late 1950's and built in the early 1960's with many upgrades to it's equipment over the course of it's close to 30 year operational life. Among the upgrades I am certain they included avionics, engines, flight controls, computers, optics, and frame modifications and coatings. This combined with public statements that the frame was stronger after 30 years of service than the day it came off of the factory floor to me infer it's capabilities far exceeded the original 1950's designed performance capabilities.

Many years ago a friend, now deceased, told me of monitoring radio reports of the last flight of the SR-71 that was donated to the Smithsonian. That flight was from LA to Washington D.C. He swore that he wrote down the time it left LA and the time it arrived in DC. He consulted a map and did some calculations. He came away with an average speed significantly higher than they would admit to at the time. And, being an average that included take off and landing, the max speed at altitude would have to higher. Somewhat later, when the Air Force reported on the flight, they gave departure and arrival times that were different than my friend had written in his notebook. He swore that the Air Force was covering up the actual max speed of the aircraft.

Another time: "we were going over 2000 miles per hour and I still had 6 inches of travel on the throttle." Also, in the "LA Speed Check Story" The L.A. Tower gave him 1992 knots over the ground." A knot, is 7, but MPH is 8. So there's a 1.14 conversion factor. 1992 knots = 2270 mph. And that's what Brian and his back seat man Walter were doing on a routine training mission.

My dad was a B-52 pilot who flew two tours in Vietnam. Once he was flying, he was assigned to SAC headquarters in LGM. He eventually was promoted and went to the top of LGM. The designated speed per the manual was Mach 3.2. My dad noted that if the plane flew suborbital, which it was capable of, the speed was estimated to be Mach 5 due to the lack of atmosphere. Only the airframe, the engine's need for airflow, and its systems (compressor) kept the plane below Mach 3. The current x plane lacks all of those deleterious issues.

Diane Tedeschi September 2017 An expert on maintenance of the Lockheed SR-71 Mach 3 reconnaissance aircraft, Don Campbell was the SR-71 Superintendent at both Kadena Air Base in Okinawa and later at Beale Air Force Base in California in the 1970s. He spoke with senior associate editor Diane Tedeschi in July. Air & Space: Do you remember the first time you saw an SR-71? Campbell: When I was selected for the program in 1964, I was working on the B-58 program, and the first four pilots selected for the SR-71 were B-58 pilots, and they’re the ones that got me to go. They showed me a black-and-white picture of an airplane, and that’s the first time I saw what I call a Blackbird: It happened to be a YF-12. They asked me if I’d like to go work on an exciting program, and they showed me that picture, and I said sure. My first actual sight of an SR-71 didn’t come until early 1965, when I was sent to Palmdale, California, to follow the production. Was what you saw then a fully assembled Blackbird? Yes. I got to see some more later. I spent a total of about eight months between Palmdale and Burbank [where Lockheed’s Advanced Development Projects division, also known as the Skunk Works, was located], so I got to meet with all the engineers and meet Kelly Johnson [then vice president of Advanced Development Projects]...

Very interesting video - thank you. You may want to look at the max. altitude: Most reports state ~80K feet. But I have heard that there are recently declassified reports of altitude in excess of 120K feet. I heard a joke about the SR-71 - at the time the plane had just been 'declassified' (?) and the USAF admitted publicly that it 'existed'. Joke goes: SR-71 is flying over Dallas, Texas, designation 'Aspen-XXX'(I don't recall the actual numbers). For fun, the pilot calls up Dallas commercial ATC = "Dallas ATC, this is AspenXXX, requesting permission to 'go to 90 thousand feet'> Hysterical laughter can be heard through the radio as Dallas ATC staff are laughing their butts off. Finally, one ATC controller gets back to ASPEN-XXX - is a VERY sarcastic tone he says ".... yeah, sure - you go right ahead there, Aspen-XXX, and good luck!". Without a moments hesitation, Aspen replies "Roger Dallas, this a Aspen-XXX DESCENDING to 90 thousand feet". Total silence from Dallas ATC !!

I've heard this before, but you got the altitude badly wrong. ATC only controls up to Flight Level 600 (60,000 ft), above that is uncontrolled airspace. Very few commercial aircraft are capable of getting anywhere near FL600, hence ATC's doubt. The SR-71 was calling in to ATC to enter controlled airspace from above.
@DenanSevenАй бұрын
The issue of increasing SR-71's speed from say 3.2, for the purpose of this discussion, to 3.5+ is managing the positional stability of the shockwave created by each engine's Air Inlet Control System (AICS) spike and aft of spike pressure control system valves called "doors", within the interior shape of the nacelle at speed. The spike you see at the front of each engine's nacelle hydraulically moves aft in a range of around two feet, controlled by the Air Inlet Control System (AICS) as speed and altitude increase per the accel envelope. It's a carefully choreographed process of accel and decel to keep the beast in it's flight envelope. At 3.2 and thereabouts, the stability of the shockwave is very critical within a small range of motion/pressure fluctuation. The challenge is managing that system. The AICS on paper and real life can exceed 3.2M but for mission purposes 3.2 (+/- a bit) is good enough mix of getting to the target, spending minimum time over target and getting away safely and reliably. The AICS is something of a supercharging system that uses the shockwave in the nacelle to radically slow the speed of air in the intake nacelle, which conserves energy by radically increasing pressure of the air in the nacelle aft of the shockwave, resulting in very high density of O2 per cubic centimeter of air fed to the engines... So the engine produces more thrust at the same RPM as as the aircraft accelerates. The engine burns O2 and the AICS increases the amount of O2 per unit of air fed into the engines as speed and altitude increase. Brilliant system. The fuel/air/power efficiency at mission speed was higher than that of achieving mission speed...
@millionsofrecordsernieb75873 күн бұрын
Good answer and there are other limitations. One that is well known is the max inlet air temp of 427C. There's also the additional Shockwave at the tip of the spike...the angle of deflection increases with speed. At 3.2 I believe it is 18 degrees, which angles out past the wings. However at around 3.5 the angel is such that the Shockwave would interfere with the wings and create substantial drag. There are also temp considerations for the engine components but I can't find precise data for this.

This was due to the fact that the temperatures associated with going Mach 3, always caused a failure in one system or another, of varying urgency. Due to the nature of the Blackbird’s mission sets, they didn’t actually declare emergencies because it was just overall assumed that the plane was going to have issues of some sort, during and after a mission.

David, was a complete geek and very approachable guy. They started talking about what they did for work and the pilot talked about flying the BlackBird and the other guy said he was on instruments. David told them he saw them on radar and they told him he didn't. David asked about the plane and they said they put their food on the glass to heat it up before they ate. The plane has a problem at speed with the engines lurching yawing the plane suddenly. "Feels like a train wreck. Slams you against one side of the cabin or other." David asked how fast it was.

While the phrase "top secret" is thrown around a lot, there are levels to it. I was in the Air Force monitoring radar and I had a top secret clearance. When you have access to military machinery of that kind, you usually require a clearance. But that doesn't mean I knew how it worked or they told me JFK was an inside job. Many people with a top secret clearance don't know what you think they might, but there are others who do. If he worked in a gated facility where he needed his ID checked at two stations, plus needing a passcard to get in before having his ID checked again...THAT is what a real security clearance is. The government isn't worried about the average person in the military. Defense contractors, engineers, anyone working in R&D has a clearance and are probably monitored like you wouldn't believe.

We can use a little common sense. 1) The sr71 uses different fuel that acts as coolant. 2) The sr71 leaks said fuel until its frame expansion at speed and altitude (meaning the entire plane has to heat up or warm up while flying in order to stop shedding fuel. Can anyone mention another plane needing to do that? So it's safe to say that the sr71 is a mach 3.5 - 4.0 aircraft. I would dare to say it is closer to mach 4.0... ask the Russians how fast were there missiles that couldn't catch the sr71, not even shot from head on.
@millionsofrecordsernieb75873 күн бұрын
Actually the SAM-2 was as fast, in stage 2 (liquid fuel) it was approx 2600 mph. It's not quite accurate to say the SR outran missiles..SAM-2 missiles didn't give chase like a homing missile. Instead, a firing solution was needed and they could never achieve this because SAM-2 radar reached about 70 miles and that's not enough time for a plane at 3.2 Mach and 80-85K altitude, not to mention the plane had effective ECM and stealth characteristics which made it even more difficult. In effect they just needed a lucky shot. However when the crew knew of a launch they did take evasive action by slightly increasing speed and possibly course and altitude adjustments. One missile did explode close enough to impregnate an SR with shrapnel but it was just superficial damage.

What I thought would be a meteorite falling into the atmosphere, white/greenish trail, that ends up falling, burning out, ended up not descending, and continued to burn, heading east out to the ocean. ATC didn't see anything on the radar. It was traveling quite fast, but hard to determine height. I asked my FO, who was a former F15 pilot, if he had ever seen anything like that. He hadn't.

Just look at the numbers for the F-15 and F-22. They're similar weight machines, and (using wikipedia's numbers for expediency) the F-15's engines at full afterburner fall short of the F-22's max thrust without afterburner. And from that we're expected to believe that the F-22 has a max speed of Mach 2.2? (Wikipedia says F-15C max Mach 2.5, F-22 Mach 2.25). Alex himself has spoken a few times about the power of these newer engines and the even more absurd next gen replacements in the pipeline. Now I'm sure the Air Force doesn't want their Raptor pilots tearing their stealth skins off at Mach 4 for no reason, but basic arithmetic demonstrates that claims like a Mach speed reduction of 0.25 from F-15 to F-22 is more than a little suspicious. Then again, people still make claims about certain ground vehicles that I know from my own experiences (and info that I doubt is well guarded anymore) are just not true or even logical.

I worked in RACOM (range communications) and every time the SR-71 took off at Edwards doing it's research flights at 80,000 feet and Mac 2.5+ all of the ground instruments in the control room zero'd out. We all had clearances of at lest secret and still we weren't able to confirm anything above that altitude and speed. Every single flight was the same and very frustrating because I got to see it and touch it up close and it was a gorgeous aircraft. If it was a woman, it would be a 10+ but it did leak like a sieve on the ground because it needed to refuel in the air and then when it was at speed, it would expand and seal up and was good to go after that.

And the United States always reports levels that are far below the actual performance. To expect anything else as foolish and to classify such claims as lies is inaccurate and unfortunate. After they tell you that the information is classified, What do you expect? You also need to realize that the SR 71 often operated at the is maximum " Edge" of it's flight envelope. Often the maximum variation was less than 10 knots. The term maximum speed is not really the primary issue as the Flight Envelope definition includes far more characteristics. To state that the SR 71 was the fastest "operational jet" (Which excludes the XB70 and others) is accurate. Since the maximum performance is still classified, I can't speak beyond this.

Since the plane was going to wind up in a museum after it landed, they weren’t worried about overheating the aircraft, so they were going to “show off.” The original flight plan was under an hour from LA-NY, but without a full fuel load, they had to throttle back. Even so, the plane came close to Mach 3.4 (2242mph) at one point in the trip.

Thanks for sharing. Yes indeed quite a thing to witness. We were lucky to have a fly by at the Rancho Murietta airshow outside of Sacramento in the 1980s. The sound was far different than any aircraft, on approach it had a roar that was unmistakable and menacing!

They didn't lie, it's called keeping your enemies in the dark. The ceiling and speed were both 'rated' for a certain amount, but I guarantee you that they were Much higher than ever openly stated.

My favourite question Brian shul was ever asked was what’s the slowest you have over on in it he said now keep in mind you fall out of the sky at 290 knots but it was in England and was foggy and we were asked to do a fly over for airforce cadets he said he was looking outside to find the airfield and then said to himself ding you haven’t looked inside the cockpit in a while to his horror realised they weren’t flying they were falling out of the sky he lit the after burners and they started climbing just as they poked out of the fog they were over the airfield and the 12 cadets and their leader were standing on the towers balcony he said it was a quit ride back to base as his back seater Walter didn’t wanna talk to him when they landed the Col in charge came up and said his friend with the cadets said he couldn’t describe it it’s was incredible brain said it was nothing his back seater then walked up to him and said 162 knots what did you see pilot 😂😂😂 RIP Major Shul

The Air Force said the Blackbird had a top speed (unclassified) of Mach 3. Everyone in the aviation community knew this was a gross "understatement."

While serving in the USAF from 1976 thru mid-1980, stationed at Ellsworth AFB in SD as a jet engine troop working flightline, I had the opportunity to witness 1 of these planes land as a transit bird at our base. The SP personnel very quickly escorted the taxiing aircraft to the 90 row of docks(last row at north end of the runway)into a waiting dock that already had doors open(they would accommodate a B-52 easily)and shut the doors after the aircraft shut down. (We also had another one set down about a year or so later, same deal). I knew a couple troops in the SP squadron who were working security at night up there, they told me you have 3 minutes to go inside and look at it after scrutinizing my line badge. I did so and was amazed at the size of it, couldn't help but notice all the fuel on the floor because the SR-71 was designed that way to allow for expansion when at speed and would leak like a sieve when cool. We took our look at it and the SP people said, "You didn't see this tonight, right?" "Nope, didn't see anything....." Personnel were brought in from Beale AFB to make necessary repairs and bring start carts for it. It departed 2 days or so later, and the resultant sound/shock wave from the burners lighting off was actually much louder than a KC-135A tanker using water injection! Very cool to see this display of sheer power, that jet was at altitude and leaving a contrail inside of 5 minutes after a steep angle of attack climbout, and could still be heard loud and clear after it disappeared from sight. So cool to see one in person, and to see it fly!

He mentioned the word "habu" in his introduction. That terms is associated in my mind with Okinawa, Japan and its very poisonous indigenous snake, the habu. Around 1984, I was working for The University of Central Florida as the lead designer for the USMC's TACWAR company-level manual wargame. We went on many multi-week trips to all of the Marine Corps' "garden spots" and in 1984 we were in Camp Schwab, but we frequented many of the Air Force bases for "provisions." I was in the parking lot of the PX at Kadena AFB and heard this very loud noise. Looking up, I witnessed an SR-71 taking off like a missile. It was very memorable. A few years later, they were gone. Glad I caught this even at least once in my life.

I was stationed in Okinawa when the Habu's were retired and flown back to Beale. I was called to a loud noise complaint at the Officer's BOQ. Upon arrival, a bunch of the SR-71 pilots were having a party before leaving. It was no big deal, and they weren't "trashed", they didn't realize things had gotten a little too loud. All were cool about it. After I explained what I was there for to the ranking pilot, we just started BS'ing a little, and I happened to ask, just how fast "really" was the Habu. He told me he didn't really know. Anytime "the enemy" sent a SAM, if it looked like it was going to get close, they just increased the throttle a little bit until the SAM ran out of gas, then backed the throttle down. We both laughed, I handed his ID back to him and told him to have a good night. I did notice that our Shift Commander's wife was in the room partying with the pilots (and she was trying very hard not to be seen) ... but that wasn't my business.

A lot of people don't know this but, it was the tanker Navs that ran ALL of the air refueling rendezvous...I never missed an A/R... Oh boy, do I have a lot of stories. The best one is when in the late 1970s the SR flew round trip out of Beale and return, he flew about a 12 hour sortie that day!! I believe that was the longest mission the sled flew.....Anybody out there know of any others? Thanks for the reply.

Alex, I just love how excited you get just doing your job! You’re a lucky man, doing what you love - good for you, brother. And thank you for contributing yet another Blackbird episode to my ‘Blackbird’ playlist collection; there are never too many. And thank you, EVERYONE, who leaves comments about technical details and especially prior experiences with this entire program. There are currently over 1200 comments, and I will go through the entire list. I ESPECIALLY appreciate reading from the people who worked on the design, manufacture, maintenance, and overhaul of the airframe, avionics, fluids, and the J58. It’s great to have watched so many pilot interviews, but there’s just not enough written about and by the folks that made the ‘Bird and kept it flying.

I listened to a talk given by Brian Schul detailing his Air Force career and transition into the SR-71. He certainly didn't lie about the top speed. When asked he answered truthfully; no one really knows, it just keeps accelerating until you chicken out and back off (the throttle).

My neighbor (recently deceased) designed the Pitot tube at the front of the SR-71. He had a great story about discussions during testing and how he determined they were running ridiculous speeds based on thermal induced discoloration of the Pitot tubes metal.

When I worked as an air traffic controller we had one call us from above controlled airspace over Pensacola Florida declaring an emergency. He wanted us to be aware that he may need a lower altitude since he had an engine out. When asked where he wanted to land, he said he was going back to his base in California.

There is an old tale where an SR71 pilot radioed the tower asking for permission to enter flight level 70. The tower laughed and asked "How the hell do you plan on getting your aircraft to flight level 70?". The pilot answered "By descending."

My dad was in the Air Force temporarily assigned in the UK and overheard a U2 declare emergency (flame out) as it was passing over England on its way out of Europe headed towards the US. The controller asked if the U2 wanted them to scramble the Azores? Pilot’s response: naaa, I’ll just glide it back to Edwards… so, the plan, with the engine not running and powering the plane is to glide all the way across the Atlantic ocean and then all the way across the continental United States… The machines (and many of the men operating them) of that era seem so much better than what we appear to have today.

I remember how F15s used to hit Mach 2.5. First, you took a F15 that had been totally overhauled. You made sure that it was clean with no external loads. Then you would fly it up a waiting tanker and refuel. Once you refueled you made sure you were at 30,000 feet plus and gave it full afterburner and used the V-Max switch. Once you hit Mach 2.5 you would throttle back and land immediately, begore you ran out of gas. Then the would have to totally overhaul the aircraft because the V-Max would damage the engines.
