How I reconstructed the SR-71 Blackbird (in-depth research, 3D modelling, animation, and more)

The process for making my artwork has become quite involved, and it's my pleasure to share it with you. At 55 mins., the original SR-71 cutaway explainer video is my longest, most involved work yet!

Making a 40min video to explain a 55minute video! What a legend! Thank you!

[@RobertCraft-re5sf]

Yeah, I really appreciate him showing the research photos and sources. I've never seen many of them before.

[@animagraffs]

oh there was so much more too, there always is with Animagraffs! and you're most welcome :D

[@Synaptic_gap]

Truly incredible! Your work is in a class all it's own. Would love to see your treatment of the Apollo lunar system, if you ever get around to it. @@animagraffs

[@khalilbtp3593]

A 55 min video that takes months to make.

[@felio_]

​@@animagraffsSo part 3 is confirmed?

[@onthe_brink]

bro just casually makes everything from scratch. this guy is on another level

[@Whisper555]

It's not a boast when he claims he is above average.

[@Lezarddd]

Making your own stuff from scratch should be the norm tbh. Still phenomenal work.

[@cristosocorromedina580]

💯

[@helplmchoking]

I mean, even Mustard, who we all know is pretty awesome at pairing gorgeous animations with great information, uses pre-made models. This guy is on a whole different level, the detail is amazing

[@JacoblaageKragh-gc4em]

"just allow me to warmly invite you to start exactly where you are and go from there" so nicely put!

[@animagraffs]

We gotta work with our own inner landscape, and we can't b.s. ourselves for long. To say we all haven't been burned by being too hopeful about an endeavor is probably a lie. But to, in turn, believe we're actually incapable is also not true. In the end, it comes down as a simple invitation to try, respecting all sides of ourselves. Both the weathered skeptic and the boundless inner child, and everyone probably has flavors of both that weigh in with every choice we make.

[@honor9lite1337]

​@@animagraffsUnderstood.

[@romaaeterna1378]

Above average is an undestatement.

[@outdew7010]

I was a crew chief on the SR71 (971) and I loved the video one of the best I've seen... THANKS!

[@dannydetonator]

TY for your service.. from Europe!😅

[@mbenn8168]

At school - the best teachers loved their subjects didn't they? Jake's enthusiasm says it all. It's a happy time when a new video pops up. Thanks man.

[@JohnSmith-mn4wf]

Please note you your channel is one of the best 3D graphics / educational channels in existence. Thanks for all your hard work and educating us all.

[@adrianqx]

The research alone would weed out 99.99% of people who would dare take on such a project , impressed is an understatement , great to see a man doing what he loves !!

[@ddontyy]

I dont know why you would use Blender Polygon modelling instead of an Actual CAD software that is designed for actual exact measurement and sub mm tolerances. Still impressive though.

[@Jixijenga]

@@ddontyy I believe I can answer that as I'm transitioning from writing novels to making visual media. I'm doing what he's doing, but while I'm learning how to do it. I started using "the 3D stuff"-back before I knew the terminology-when I was in high school in the early double-aughts. There wasn't much to do in rural Minnesota, so I wanted to make a game and back then pirating was both easier and more difficult all at the same time when compared to now. These days we are spoiled with options. My copy of 3DS Max wasn't working right so I went to the very unknown SketchUp, which had recently been acquired by Google. Everything I know about making something in a three-dimensional, digital space was self-taught in SketchUp, which fell in this weird crack between the different spaces. CAD software is, indeed, accurate down to sub-millimeter and this is vital for engineering projects that need exact tolerances in the real-world. You can't wing it where metal meets metal, or metal meets meat, because it just won't work. My mind works on this level-this is common among men who have to fabricate and fix things with no plans-and SketchUp can do it too. Many of my own fictional creations benefited from being able to just do it out of the box, to go where my mind took me, and when I decided to graduate to better tools I found that Blender really didn't encourage that kind of workflow. That's not what Blender is for, though. Even though we're seeing machines built with slide rules and mid-century grit-creations of men who thought down to the millimeter-we are watching them through a video. These are not technology demonstrations with exact tolerances so a shop somewhere can churn out parts. No, instead these are short films to explain how the technology works and cinema is not found inside of a millimeter. Nothing on the CAD side can hold a candle to Blender out of the box and as you saw in the video there is room to make it do much, much more. I hope that answered your question. (I also hope that I'm not stepping on Jake's toes here) Frankly, this is all for a video that entertains as well as informs and this is precisely where Blender shines brightest. Plus, it's free! :D

[@RomboutVersluijs]

​@@ddontyybecause he doesn't need to model precise, he models to get a message over to the viewer. The viewer won't see if the measurement are not 100% exact. Ps the initial comment was about research, not sure why you comment about poly modeling in blender to this?!

[@helplmchoking]

@@ddontyy Because you're modelling for rendering and VFX? CAD gives you ultra precise models that are perfect for validating designs, producing accurate measurements and tool paths for manufacture, materials analysis etc. but a big downside is it REQUIRES the perfect accuracy and all the technical details. You need to input precise measurements for every single part, which isn't available or necessary for this kind of model. He's not designing or building an aircraft, he's creating a 3d representation of the aircraft and yes he's trying to be as accurate as possible but CAD is unnecessary and frankly is for a completely different process. All that aside, the software used has nothing to do with the research the comment was praising

[@robertg.2276]

It is just unbelivable that all this work is one man effort...level of detail,execution,script,video edit....one man band....unique on you tube...just unbelivable....respect...it would be nice to know how many mouse cliks and how many mouses are actually consumed for each project 😂😂😂...keep on doing what you do..can wait for next project

[@Northmaverick1]

The amount of research, preparation, and due diligence you put in is comparable to your 3D expertise! It's staggering! Thank you for your work! Absolutely the best!

[@victorwhitacre1885]

Don't stop. Your passion for modeling matches my curiosity. Looking forward to watching these when my son asks, "Daddy, how does that work?"

[@AlexMeyer.]

Thank you for this!! Col. Richard Graham was one of my associates, and I'm so proud every time I see his work being helpful to others.

[@borge2014]

Please make longer videos, we do not tire of watching. Love you explained the music concept, and that is what I felt, gliding on space! Anybody out there wanting a 2hr video? Have to re-watch the original SR - 71 Animagraffs again, yay!

[@TheArchitect515]

My wife's grandfather was an SR-71 mechanic. He doesn't talk about it very much for some reason, but i think its really cool. I've been a big fan of the aircraft for years, and your video was the most in-depth information I've ever seen about it.

[@Autorotate5]

Your work is absolutely spectacular! I'm a 68 year old former helicopter pilot. Thank you for your outstanding detail

[@jhamptonjr]

If I had been born 15 or 20 years later than I was I might understand blender. I can't believe blender had the tools to make this possible. Thank you for putting all this effort into this!

[@mbraun777]

Years ago, it may have been necessary to write Fortran code to describe a pattern of nodes in some type of coordinate system, possibly spherical, then write more Fortran code to define node connectivity for elements, finally loading all that info into Ansys to generate part of a 3D model. Since then, I've had to completely relearn CAD, for work, as well as play, as in game meshes. What you are doing is so much more than mesh creation. This is cinematic. I can say, having done my share of hunting for dimensions and creating 'dummy' parts, you exhibit a love for what you do - a satisfaction in a job well done. I wish you success.

[@animagraffs]

You're one who posses the old knowledge of talking to the machine directly! lol, much respect, really. While we have extrapolations on extrapolations now, knowing what's underneath things always makes a craftsperson sharper. I downloaded "pov-ray" in the 90s. It's a bare ray-tracer software, where I had to write code to make a scene. I had no idea modeling software even existed. It was wondrous even so, and I stayed up many late nights making 3D scenes with code. As an artist at heart, the math-y side is really difficult for me. But I can see how it shaped me!

[@imCarlBrown]

Just outstanding! I watched the video all the way through. Then I watched it with my three sons. We’ve watched several of your videos and they’re awesome. I first learned about the Blackbird while in a library in the early 1980s. It’s such a testament to the human mind. Great job!

[@tortap]

Hold up! So you learned all the mechanics for an entire secret spy plane, built it in 3d, animated and narrated it... And then you composed the music that goes with it? Mindblowing

[@dannalbob]

I had a giant SR-71 poster up in my room as a kid... I still think it's the most badass looking plane.

[@payfusion]

I have never found a reason to comment on YT. In today's world, it is extremely rare not to find a single negative comment (on the work you have shared) is a testament of the perfection that you have acheived. You deserve every compliment that you have been showered upon. I am truly inspired by your dedication to your craft. I can't wait for you to release your next piece of work.

[@lukasvonniederhausern6153]

People like you truly keep the spirit of the Internet alive.

[@benrothstein9547]

I am a huge SR-71 fan and aerospace enthusiast with a curiosity of how things work. You've managed to capture detail of this jet that I've learned and had wanted to learn over my entire life in an hour long video. I was wondering how in the world the video was made. Thought it was a team of people to create such a complex presentation. To learn it was only you and a ton of research has me blown away. Well done and thanks for educating us. Subscription earned.

[@williamromine5715]

Your enthusiasm(sp) spreads to your viewer. I am 82 and computer ignorant, and have no idea how you produce such beautiful videos. I have been looking at You/Tube since 2020, and stumbled on your channel only recently, but I am so glad I did. Thank you for your hard work in producing your videos.

[@methylmike]

dude! this one went sooo hard the engines blew my mind

[@StratoArt]

You sir are an inspiration!!! Coming from a KC-135T crew chief who refueled my jet with JP-7 for the Blackbird (and JP-8 for the tanker itself) for one of the last SR-71 missions in 1998.

[@markp.9707]

Thank you for your service and what a role you played sir. Bless you and your family.

[@rutgervitez4438]

Your Blender skills are absolutely insane. Keep up the good work 👍

[@MadEyeMose]

Astonishing accomplishment. I was fortunate enough to be assigned as a aircraft mechanic to 9th OMS from 1986 - 90. Most engine repairs were checked out with basically an idle run in the hanger. Occasionally components replaced required a full after burner run. If the SR-71 was run at much above idle while in the hanger, the hanger could be damaged. Full afterburner test required towing the aircraft for more than a mile to the edge of the runway. The SR would be connected to the run-up pad with two 3" 12' long rods and bolts. Airmen (me) would run the start cart, and then stand by the fire extinguishers just in case the grass caught fire. We would have contests for a picture of beer to see who could step closest to the afterburner. I could get close enough that I could no longer tell if my feet were still in contact with the ground, and still lost to a guy who weighed 20 lbs less than me. We would also toss rocks into the diamond and enjoy the splash of the rock on the blast deflector. The trick is to watch the blast wall as you toss the rock and hit the diamond. How fast would those rocks be traveling? Beal run-up pad: 39.12308676335525, -121.422495740995151

[@auntbarbara5576]

You are the best kind of teacher. Jake, if kids had instructors like you they would be blessed indeed.

[@gonzametal9677]

I'm studying 3D with Blender, that's how I found your channel, and I was inspired by it, far from discouraged, your work motivated me to go further, so than you very much sir!

[@sw653j]

"I know that I am above average, talented." Watch this to the end and you understand what an understatement this is...

[@ferociousfrankie]

I think the coolest thing you did was convey the "spookiness" of the blackbird. It was so advanced for its time and was so innovative it was almost alien. You captured that in educational content which is hard to do.

[@Chris-qc2kd]

Dude, you are not just a 3D artist, you are THE 3D artist. Your dedication to these videos and artistic skills are extraordinary. Keep up the excellent work!

[@stevej061069]

This is, without a shadow of doubt, one of the most impressive things I have EVER watched. The actual video is a stunning piece of work but this really goes a long way to demonstrating the insane degree of work behind it. I salute you. Incredible.

[@Quoth_]

It warms my heart to see your eyes light up when looking at these old schematics and your passion is easily seen and it's very infectious! Thank you!

[@geraldstokes5661]

I worked on the blackbird , from 66 thru 69, it is quite a aircraft. Ur doing a good job with ur drawings...

[@OrangeDurito]

The sheer brilliance contained in this video is so overwhelming that my artistic skills feel almost negligible. But as you said in the beginning not to feel like that, I would like to shrug that off and actually strive to reach this stage. You are an engineer, a programmer, a 3D artist, a musician - you are like a ONE MAN ARMY of an inventive mind that can connect with common people!!! You sir are an inspiration.

[@animagraffs]

I'm absolutely sure that what you bring to the table is different than what I bring, no matter the skill level. And the world needs authenticity like it needs water, so even your smallest efforts bring a different flavor into existence, even if only you see them. Also thanks for your compliments, it's awesome to hear from folks who appreciate my art :)

[@Vastafari34]

There's a helicopter (Sikorsky H-60) that the Army, Navy, Airforce, and Coast Guard all use because of its power, reliability, and versatility. It is one one the MOST famous and versatile helicopters in our great military. It would be a service to our nation and all the great men and women who work on, and fly in these amazing aircrafts if you did a video on the Sikorsky H-60. Each branch uses the same base model, but then outfits them specifically for their needs. For instance, the Army's Black Hawk has a different assortment of accessories compared to the Coast Guard's Jay Hawk. Even though the base model Sikorsky H-60 has different models (Black Hawk, Sea Hawk, Pave Hawk, Jay Hawk and other's as well), a video on the the base model H-60 would very easily become a primary training tool for EVERY branch of the military and it would be used for decades to help our great service men and women become better familiarized with the planes they work on and fly to help recue citizens at home and protect our freedoms over seas.

[@infontay]

Protect our freedoms overseas? You mean war monger and terrorize smaller countries for financial gain and power for corrupt politicians?

[@franciscobizzaro]

Sounds like a plan!

[@Epic_Eggroll]

I love this idea, I think he would have a lot of fun dabbling into helicopters.

[@Vastafari34]

My friend is a rescue swimmer for the USCG and he took some time to show me the basics at the top of the plane where some of the flight controls connect to the wings, and it is truly a remarkable beast.

[@Epic_Eggroll]

@@Vastafari34 Man that sounds amazing, i really interested in being a rescue swimmer

[@TovarasSanders]

have over 20 years experience as a designer, and am using Blender occasionally, and thank You so much for starting Your video as You did, because I was close to sell my laptop and go flip burgers at McDonalds. Outstanding skills, am starting to put in serious hours into Blender now...

[@a7madness210]

i really admire your english speaking skills, for a non native english speaker.. i truly get inspirations from your way of speaking, some may think learning language from an insane detailed video is weird but that the beautiful thing, even the unnoticed details you do people get inspired from... thank you sir and all the best

Technology: from the Greek tekhnologia ‘systematic treatment’, from tekhnē ‘art, craft’. Seeing the process and technique behind the art is simply awesome. Thank you!

[@politicsuncensored5617]

I just found your channel recently & enjoy it greatly. Your how to video on the SR-71 is the best. People get to see your great enthusiasm in what you do and that transfers to the viewer like myself. I have been building model ships since I was 12, but stopped about 5 years ago. I find it relaxing and enjoyable watching videos like you make rather than staring at a TV screen. Thank you for all the long hours and hard work that you do. PJ

[@deisyperez6297]

Just wanted to say to keep going, even if at some point the views may no longer pour in we need these videos to educate the world on the beauty of how things work on a deeper level.

[@arko986]

I want to remind you of something: You are not only above average, but you have also become a brand. You are Animagraffs, my friend.

[@animagraffs]

I love this. When I started out to make my first Animagraff project, I didn't fully realize the deeper parts of me that would come through in the work. It's a testament to finding something solid in life, that with each project, those desires further unfold before my own eyes. Like being surprised by a part of myself that I wasn't fully acquainted with, but in a good way. It's satisfying, down to the deepest things that make me, me. I really appreciate your words, and you noticing the brand of Animagraffs. For how surgical and objective the art form is, it ends up being more personal than I would have ever imagined at the start.

[@PASquared]

This is truly a mindboggling commitment for one video, and it is so greatly appreciated. Incredible!

[@cobberpete1]

Be yourself and don't compromise. Your work is over the top. I have unsubscribed to a few channels because the 'Sponsors' take over the channel theme. Long may you make a living out of it.

[@dogmandan79]

I was at Blackbird Park in CA last week and saw many of these same components. Its fascinating to see this video and to see the part IRL. I dont usually watch 55min long videos, but this one was a definite exception.

[@Bobby-ot7td]

I fell in love with the SR-71 when I was like 10 or something. My family went to the Museum of Flight in Seattle, and I swear to god, the moment I saw the SR-71 my heart was captured by it. Of course I did not know the absolute insanity that went into this aircraft, but I still fell in love nonetheless. Over the past 15 or so years, that love has not been tempered in the slightest, and I have to say, your video brought me a massive amount of joy. I could see myself watching this time and time again in the coming years. Do not ever stop. There are many people who have a passion for learning, whether they know it or not, and these videos are some of the greatest I have ever had the pleasure of watching. I can only hope that this video, as well as all your others, can inspire and bring joy to others the same way they do with me. Never change man.

[@BraggenritesNetwork]

Dude, I am frustrated not engineer. Meaning that I went to school for graphic design, but I should have done the work to become an engineer. I absolutely love your channel and greatly appreciate your hard work. As I kid I used to take apart my toys, to see how they work, and your videos really feed into my curious nature. And the details, oh boy the details. They’re just awesome! So thank you. These behind the scenes are equally as enriching, as it shows us how you got to the videos. Insane research! Again, thank you. Anyway, I just wanted to let you know I truly enjoy and appreciate what you do. Keep up the great work! 🙏

Nice work dude! I'm both a prior serviceman of the Cold War Era and an old hand in video game development, so you killed two birds for me with this project. Your passion for this is evident in your voice and your work, so bravo. Btw, that manipulation of the materials is called UV Scrolling. I started in games before the Xbox launched, so I would've sold off my kids for that ability-and our textures averaged 16x16 pixels, so I would've sold the babies' mama for the image features you're using. Again, splendid work!
