XB-70 VALKYRIE | Wake Vortex crash explained

[@RobSchofield]

I've been waiting for someone to do a continuous animation of the crash sequence for years - well done, this is absolutely excellent.

[@Mike-Bell]

Very happy when my efforts are appreciated. Thanks 😊

[@clint9040]

There we go. Yes thanks dear fellow

[@JoeOvercoat]

The animation of the view from the cockpit of the overflying B-58 speaks volumes. Meanwhile, I didn’t realize they been flying around for so long. What the heck it does it take to take a photograph? On station for more than 15 minutes?! Seriously WTF.

[@martentrudeau6948]

Fascinating history, stunning looking airplane.

[@anteshell]

@@JoeOvercoat Well, it takes quite a lot more than 15 minutes. In 15 mins you can get maybe a couple of good photos while walking on ground around the plane, IF you have made a strict pre-plans on what viewpoints you want photos from. When flying in the air, you are very lucky to get just one. From your comment it is clear that you lack the relevant knowledge on both taking photos and how planes behave in air to make an informed opinion about it. Seriously WTF. Why the hell people need to have their stupid opinions voiced? Go learn these thing. Make yourself informed and then make your opinion. Otherwise you'll just make yourself a fool.

[@davideberhardt4977]

As a former USAF Pilot, I was humbled by the fact that such a great pilot could have such an accident. This video could be shown to all incoming USAF student pilots to teach them about safety and always being aware to never let their guard down.

[@MisterIvyMike]

This was the first video I saw about that accident that mentioned the stress to be highly concentrated for 40 minutes and the effect of a short distraction. In some other videos or newspaper article I heard or read that the accident was caused by Joe Walker flying to close by recklessnes. Everybody who flies know how fast a short distraction can get you in a bad situation. Thanks for mention that. That puts that accident in a different light!

[@JoeOvercoat]

Now I wonder why they were in this formation or anything like it for so long. Especially back in the day you could only take so many photographs. It was film. What were they thinking burning that much gas even?

[@CorePathway]

Fact: Walker flew into the Valkyrie. Was it a stupid mission? Was he distracted? Maybe and maybe. Explanations don’t change facts tho. It was an unfortunate, unforced error.

[@winternow2242]

@@JoeOvercoat they probably realized that this was their 1 chance for a photo op, so they better make the most of it. Also, unlike digital cameras, film cameras can't show you previews of your shot, so you have to take as many as possible. This is a guess, but there was probably some hope that a splashy photo spread might lead to renewed consideration of the B-70 or even newer planes.

[@JoeOvercoat]

@@winternow2242 yes, I think they were concentrating on getting that ‘best shot’ in a difficult shooting environment and became complacent as to the dangerous conditions that the formation required. Personally, I lay the blame on the leadership that dreamed this whole stunt up and then didn’t put strict limitations on what would be involved in the shoot like not pushing the safety envelope. All for what? A great calendar shot, might even had made the cover for that one year.

[@davejones9469]

It's true. I was a butcher at a high end shop, and the only time I ever cut myself was when a gorgeous woman walked in and I did a double take lol. Stabbed my thumb to the bone once while steeling and one of my favorite customers came in...oh my twenties, if I could redo you...

I was intrigued by the new info of the higher flying B-58. This is the first I’ve heard of a possible distracting visual. I recall being in highschool when this accident occurred. And all for a brochure cover photo! Certainly wasn’t worth the cost of 2 expert top flight pilots! Thank you for the excellent description and clarifying visuals!

[@MatthewPettyST1300]

I've seen lots of videos of the incident, but this is the very first time any mention of the B-58 flying way over head that might have caused a distraction . a small little side note as an older teenager who built lots of models. On my display shelf in my bedroom I had a XB-70 and a B-58 sitting side by side. Right next to the Saturn 5 rocket that could separate into all the staging to include the Lunar lander you could attach to the nose of the Command Module. So many more from the SR71 to the X-15 and my pride and joy a completely transparent P-51D on a stand that you could raise and lower the landing gear and spin the props by pushing a control button. I was a teenager who is now 68 years old :- ( . memories....🙂

[@MatthewPettyST1300]

Being big into Rocketry, I had a few extra D-cell engines I mounted into the XB-70. I went to my local school yard and set them off. The flame warped one engine port side and sent the XB-70 into a corkscrew about 10' off the ground and 40 feet off the launch pad. I've got pictures with exhaust trails of about 3 complete turns around everyone. The X-15 had a joined epoxied 2 D cell and was last seen screaming out over the Pacific coast at 100 foot altitude straight to the horizon 🙂. Many of my models met their end in much the same glorious way.

[@justicewokeisutterbs8641]

It's cool to hear your stories of your models. In the mid 1960's my folks had a little hobby shop in Ft Worth, Texas near the Camp Bowie traffic circle. It, (and the elementary school I attended), were right under the flight path north of Carswell AFB and so we got to see lots of B-52s, tankers, Hustlers, the F1-11 and other fighters I never learned the names of flying pretty low in and out of the base. Every year the base had an air show and we could see the Thunderbirds performing from that area. One year, I'm pretty sure it was 1965, one of the X-B70's came to the air show. The local radio stations actually tracked it's movements so locals could go outside at the right time to see it. It flew over my school coming in to land on its arrival. Then when it left for California after the show everybody was able to come out to see it take off over our heads. It was absolutely the most beautiful, charismatic airplane ever. I fell in love with it and have never recovered. As a kid I thought it looked like a big, white dragon. It was really loud on takeoff. We were used to loud takeoffs but NOTHING compared to those six engines roaring when it blew over. It made a second pass and then headed west. I've heard that the one that came to Carswell was the one that crashed. Makes me sad, but I feel lucky to have seen it. Anyway, Ft Worth had a pretty active modeling community then. We sold RC, control line and free flight planes, and we flew every weekend to support the business. There were always people out flying. There was also a group who built plastic models. They built them carefully and did research to do the paint jobs really accurately. We would display their models in our shop window. The Aurora plastic movie monster kits were big too, as was Rat Fink and all the Big Daddy Roth character car kits, Davey, Daddy, Digger, and Danny. They were intentionally grotesque and funny. All the kids loved them. Rocketry got big later. Anyway, it was a fun time and place to be a kid.

[@MatthewPettyST1300]

@@justicewokeisutterbs8641 I too got into rocketry and launched many at my school But I went a step further. I modified 2 D cell motors and epoxied them into one long stage. Mounted it into a X-15 and lunched it out over Monterey Bay from a small cliff. Last seen screaming at Mach 10 flying level at 50 feet to the horizon. My SR 71 didn't fair quite so well.😄

[@justicewokeisutterbs8641]

@@MatthewPettyST1300 That is so cool! Great memories of great fun. I think there was something special about putting all the work into a model, rig something wild like your X-15 with modified engines and then risking it in flight. There's nothing quite like it. 😎👍

[@TitusAzzurro]

Damn. On the one hand those toys sound expensive for the time, on the other your passion saved your parents entire days wondering what presents to give you, so that’s something i guess.

[@jgonzalesm6]

F1 cars also develop these vortices-->either from the rear wing end plates or from the Y250(250 millimeters from the central axis of the car)vortex generated by the front wings and elements. F1 engineers want as strong a Y250 vortex as possible as those vortices come together into 1 big vortex which is then spread out to the outside of the F1 sidepods by the bargeboard. Interesting to see under heavy humid conditions or when its raining by either the front wing and rear wing on an F1 car.

[@mateostaplez7497]

Great video and animation. Been following this since I was a kid in the 1960s, and my father was a USAF bomber pilot in the 1950s and 60s. He told me that I might be flying it one day, as a replacement for the B-52 that he flew. I got up close and personal with the remaining XB-70 at Wright-Pat AFB in 1980, before the AF museum was revamped. The XB-70 was outside in front of the museum and I was there just before closing, when almost no-one was there and it was getting dusk. There was a jack-up extended maintenance stand a few dozen yards from it, and since I had used them when I was a USAF crew chief, I thought why not get a picture of the cockpit. I screwed up the jack stand pods and pushed it over to the XB-70, then jacked up the stairs until they were level with the cockpit and ran up the stairs to the platform. I got several pictures before a patrolling Security Police airman saw me and yelled at me to get down from there, which I did, but I was close enough to touch the side windscreen although I did not touch it. A moment of magical wonder for me at that time.

[@Mike-Bell]

Great story! Thanks for sharing. I would love to see your pictures 👍

[@justicewokeisutterbs8641]

Great story! I have a soft spot for the B-52, but oh my, the B-70 was magical.

[@nairbvel]

Probably the most comprehensive & clearly-presented description of the crash I've ever seen. Thank you!

[@DeereX748]

Excellently done, and includes film footage of the XB-70 I've never seen in any other video of the plane. This video also explains the role of wake turbulence in the incident better than any I've seen. It's narrated clearly and the graphics, mixed with actual footage, are outstanding. The research done on sonic booms, using the XB-70 is slightly tainted, because the use of compression lift with the drooped wingtips tended to focus the supersonic shock wave downward, increasing its energy in that direction. I was a youngster when this plane flew, and it has always been my favorite, alongside the SR-71. It's truly a huge aircraft, I've walked under it at the USAF Museum when it was housed in the Museum Annex hangar at Wright-Patterson AFB. The SR-71 is half its size, maybe less.

[@samsignorelli]

Joe Walker flew the X-15 above the Karman Line on 2 successive flights....and was the first person to enter space twice.

[@dieselrotor]

I recall as a child born in 65 and becoming an aeronautics and space junky, the first time seeing a picture of the XB-70 on the ground. I did not think it was real, I thought it was a futuristic mock up of a someday plane. When eventually learning of Her reality and history, (remember, we didn't have internet. Just books and magazines) I was brought to tears. Well done.

[@vertisjohnson219]

Still have a memory of seeing both aircraft at Edwards AFB in May 1966, just weeks before the accident. A/V1 was on static display while A/V2 was in flight.

[@Mike-Bell]

[@anas.g]

Amazing work, definitely deserves more recognition

[@Mike-Bell]

Thank you so much 😀

[@Triple_J.1]

The cause of this accident was partially due to choosing the Learjet as the photo ship. All the other aircraft are supersonic capable, mach 2+ aircraft. At supersonic speeds, wake turbulence is less a factor. If the XB-70 was at speed, with wingtips deflected into waverider configuration, the supersonic shock wave would have been generating additional lift, in conjunction with higher Q, meaning lower angle of attack in supersonic cruise, the wake vortex's would have been substantially reduced or eliminated. Great video. I always thought there was something else to it, considering the talent involved.

[@shrimpflea]

They never would have done a photo shoot at supersonic speed anyway.

[@ScottGammans]

This was really well done. I did not know about the B-58 before watching this, and the animation of the tragic incident was very professional in execution. You’ve got a new subscriber.

[@dandaintac388]

I've seen the surviving XB-70, back in the 70s when it was first parked outside the Airforce Museum. A truly awesome aircraft to behold. I don't think it's inconceivable at all that an highly experienced pilot of an aircraft could make a slight error. When one gets very experienced, where they feel they could do a certain task in your sleep, they get COMPLACENT. And maybe they aren't as hyperalert as they would be if they were somewhat less experienced. I think he was too close to begin with for safety's sake, but had a lot of confidence at how close he could get and how his plane handled. He glanced up, and that tiny distraction, as close as he was to the XB-70, was enough. This not a slam on the pilot, but he was human like the rest of us. So many accidents can be traced to complacency on the part of the machine operator.

[@sfdntk]

Just one brief moment of lapsed concentration is all it took, and then it was all over. What a tragedy. Fantastic video as always, Mike. You really are one of the best creators on this platform.

[@aloysiusbelisarius9992]

My understanding, from researching sources on this incident which fascinated me since I was a kid (I was about three months old when this happened), was that after the crash and during the investigation, some of the senior command involved in organizing this whole shebang paid with their careers, for letting a bunch of civvies bully past the safety protocols just to get cool film footage. One day I want to get up close and personal with the surviving plane. On a side note, when I was in Germany about eight years ago, there was a Soldier, a PFC, who I swear was a near-carbon-copy of Joe Walker...so much so I had to wonder if he had any genetic relation to him! When I showed him a picture of Walker, even he was surprised by the resemblance, as were a few others who also saw the picture.

[@DakarBlues]

I went at last to the Wright-Patterson Museum two years ago with my two kids. I have planned it for at least 15 years, too bad it was too late to elicit a lofty vocation from such an awesome sight. The Valkyrie by itself is worth the trip.

Excellent vid with clear, concise info. Uncanny parallels exist when two Sea Venoms of the Royal Navy fatally collided at RAF Chivenor in Devon; 19 Sept. 1959. I witnessed this crash and ever since, I and others at the Airshow, have always maintained the two aircraft were too close. The subsequent enquiry did not mention vortices but the Valkyrie collision shows that they could have played a part in the collision. RIP Observer Robin W.H. Miller and Chief Petty Officer David S. Chapman.

[@petertimowreef9085]

I love learning about aerodynamics and how lift works, I am at that stage where I know enough about the subject to know I know absolutely nothing about the subject. But Oh My God, the 15 seconds of animation after 2:11 made something click. You're always pushing the same weight in air down as the plane weighs, and spreading that energy out over a longer wing will per definition make wing-tip vortices less energetic and cause less drag. That was such a satisfying AHA!! moment, and I only got it because you made this video. That was a really cool thing of you to do friend, I am grateful.

[@USAmerican100]

Carl Cross tried to eject. The encapsulation retract system used gas cylinders. Forward G forces in the flat spin were so great the gas cylinders could not overcome the force and retract the seat. I read the gas burst disc actually blew. G forces were twice what NA designed for, because the missing left wing and verticals greatly increased the flat spin rate. Al White encapsulated when spin first started, before G forces reached maximum. Carl waited a little too long.

[@Mike-Bell]

That makes sense. I hadnt heard that explanation before.

My dad, Carl Hite, worked at Edwards AFB at the time as a jet engine mechanic on this XB-70. He told me that Cross couldn’t eject because he had dropped a flight manual on the floor which prevented the safety ejection pod door from fully closing. They are clamped to the seat when eject is initiated and he couldn’t move. He also said that Carl Cross, like most test pilots did, calmly talked the plane into the ground.

THAT IS THE BEST EXPLANATION OF TIP VORTICIES I HAVE EVER SEEN.....

[@Mike-Bell]

Wow, thanks!

[@Rondo2ooo]

What a great video and explanation of this tragedy.

[@r23w]

Amazing job. Especially matching the original photos with your CG.

[@Mike-Bell]

Thank you very much!

[@albeck4852]

Thanks!

[@Mike-Bell]

Much appreciated 🌟😀

The thing I love about this design was it rode it's own supersonic shockwave at highspeed. Such a smart use of that to increase lift.

The geese formation paradigm was just excellent. Makes the phenomenon instantly imprinted.. The geese formation paradigm was just excellent. Makes the phenomenon instantly imprinted..

My 3rd cousin was Carl Cross but he was killed on the crash before I was born. My grandfathers last name was Cross. I visited Carl’s grave In Tennessee when I was a child. An amazing aircraft!!!

[@michaelstadnikfilm]

Interesting insights. Thank you for showing this

[@gabrielbennett5162]

My grandfather, Vic Horton, worked with the men involved in the NASA Pilot's Office at Edwards. He was part of the search and recovery efforts after the crash, too.

very great and excellent documentary, well done.

I remember standing below the one of the runways near Boston Logan on Point Shirley and being able to hear the vortex (like a high pitched whistle) a few seconds after a plane passed overhead. Also note that most airplanes now have winglets or upturned wings to avoid the inefficiency of losing the lifting at the end of the wings to the sides of the aircraft.

[@wernerschulte6245]

Very well done ! I knew about the accident and I wondered how it might had happened. Thank you !

[@MyCatInABox]

This whole video was fantastic...just very well done. Than you👍

[@Mike-Bell]

So nice of you

[@DGill48]

As a retired physics teacher, this all makes sense. I never thought about the vortex and what it could do. Invisable but deadly.

I was in a bar at a reunion years ago in the 80's. I was talking with an ex North American engineer, and he got serious when I mentioned the X-B70. He told me Joe Walker was a hotshot pilot, and he was attempting a barrel roll around the X-B70 for the cameras, and hit the vertical tails doing so. I don't know how true that was, but he got very upset telling me. I'm quite sure he's no longer around, since he was probably in his 70's then, but that's what he told me.

[@SoaringSimulator]

When two wings get too close, the one on top pushes down the one on the bottom. There the plane that is below will roll towards the plane above. When this happens it is already too late and there is no way of escape. Unless the pilot of the plane below applies pitch down.

[@tipsymcstaggerx2173]

Excellent Job!

[@Mike-Bell]

Thanks for the visit

Thanks for clearing Joe Walker's name off of the blame list! 🙏🏻👍🏻
