What are these markings?

I was watching a video about the X-15 and saw these markings in the side of the B-52 used to get the plane to altitude for its run. I’ve never seen them before.

I worked as a historian at NASA Dryden Flight Research Center for nearly 20 years. This was one of two B-52 bombers modified to carry the X-15 rocket-powered research aicraft. The markings on the side of the fuselage represent captive-carry and launch flights. Horizontal X-15 silhouettes indicate captive-carry flights. Upwardly tilted silhouettes indicate powered flights.

Could you elaborate on your job, I like to know how people usually get into these roles
Peter_Merlin@reddit
OK, sure. I got my undergraduate degree from Embry Riddle Aeronautical University and my graduate degree from Southern Illinois University. I spent nearly a decade working for an airline in a variety of roles before getting a job at the NASA Dryden Flight Research Center at Edwards Air Force Base.
For about 20 years, I was involved with history, education, public affairs, and aviation safety. During that time I wrote numerous books and research papers, mostly for NASA and the American Institute for Aeronautics and Astronautics. I also served as a volunteer with the Air Force Flight Test Museum and pursued an interest in aerospace archaeology.
Next, I hopped the fence to the Air Force Flight Test Center, where I spent several years supporting developmental and operational test and evaluation of fighters, bombers, tankers, transports, and unmanned aerial vehicles.
During the Covid-19 pandemic, my wife and I quit our jobs and moved to the Midwest. I took a year off to finish my magnum opus, Dreamland: The Secret History of Area 51. https://schifferbooks.com/products/dreamland?srsltid=AfmBOoppX9subTklzlZ7YRGOqallNDPtNuxn38G8Xtygm3Zk0m59VOs2
Now, I teach undergraduate aviation management courses at Southern Illinois University.

Wow! What career! I have friends whose daughter just got accepted to Embry-Riddle. She’s over the moon about it. Living here in Seattle, she caught the bug early.

Nice! Which ERAU campus, Prescott or Daytona Beach? I went to both. Living in Arizona was arguably nicer but in Florida I got to spend a lot of time at Cape Canaveral.

Oh wow that was good read... Thanks !!!

Wow, I remember seeing you in the Space Shuttle documentary narrated by William Shatner. Very cool to see you here!
Peter_Merlin@reddit
Yes, that was fun one. Over the years, I've done a bunch of film and television documentaries for the History Channel, Discovery, Travel Channel, Smithsonian, Military Channel, Science, NASA TV, and others. Recently, I sat for an interview as part of an Area 51 documentary that's in the works.

Is this the standard for expressing this type of information on the fuselage of an aircraft detailed to assist with test flights? I assume, for B-52 detailed to the X-15 program, this is all they did. Did other platforms doing similar duty have the same type of markings? Like I said, I’ve never seen them before on any aircraft.
Peter_Merlin@reddit
The airplane pictured is the NB-52A, which was used primarily for launching the X-15 but also launched the HL-10 lifting body on at least one occasion. Another airplane, the NB-52B served as a mothership for numerous research aircraft and test articles. Both planes received this type of artwork on the fuselage.
An earlier mothership, a P2B-1S (formerly designated B-29A), was used to launch the D-558-2 Skyrocket and also had commemorative mission artwork.

Page 9 in this PDF shows what each marking means. This aircraft (Balls 3) is currently at Pima, and Balls 8 is at the entrance of Edwards.

I can totally read the markings now! Are marks made in chronological order? If so, is the order left to right?
devoduder@reddit
Yes, if you look at page 17 of the PDF, the first four flights on 003 are captive carry and the fifth is the first unpowered drop test and those match the first markings on the plane.
SidneySilver@reddit (OP)
I can start to understand the test mission time signature — a number of captive flights after a few either powered or glide flights. Great way to make small incremental changes. So cool!
SidneySilver@reddit (OP)
So cool!
CounterSimple3771@reddit
Yes, thank you. Truly
SidneySilver@reddit (OP)
Really cool stuff. Thanks!
I-LOVE-TURTLES666@reddit
Damn that’s cool. Thanks for your knowledge
F6Collections@reddit
What about the one that’s pointing down? Glide?
Peter_Merlin@reddit
I believe so, yeah.

Thanks!

They're pictures of missiles not sure if they're kill marks though

Its cuniform writing, obviously someone was unhappy with the quality of copper.
Velvet_Llama@reddit
Amazing reference.
Intelligent_Age_6284@reddit
NB-52A “the high and mighty one” or “balls 8” denotes the drops and records of each time the X-15 was launched from it. I have pictures from Pima where The high and mighty one is of the markings if you want.

A complaint to Ea-Nasir about his ill-fated attempt to branch out into forging aircraft grade aluminum?
Techhead7890@reddit
It really does look like cuneiform wedges!

Underrated comment
Haydn__@reddit
its a big red circle, probably done in Microsoft Paint
RoughConqureor@reddit
It was king Ashurbanipal’s bomber. 630bc. It’s obviously cuneiform writing.
xeridium@reddit
That's Ea Nasir's jet. Stay away from him he sells shitty copper.

I actually understood that obscure af reference. (Good for you...pretty funny.)
phoneguy247@reddit
Controller cheat codes for the X-15?
SidneySilver@reddit (OP)
Ha!
tiag0@reddit
FWIW the 2 NB-52s modified for this are on display. 0008 (Balls 8) is on display at Edward’s AFB, while 0003 “High and mighty one” (the one pictured) is on display at Pima Air Museum. Pima also has a replica X-15, they have/had placed it under.
Clicky here to see a recreation of that screenshot/picture you shared on their instagram

Totally cool! Thank you 👌
Key-Monk6159@reddit
Just want to express my amazement and appreciation for the incredible wealth of knowledge here. And more importantly, the willingness to share.
Thank you all!

Right! I was thinking the same. It’s why I love Reddit.

They were the X-15 launch mission scoreboard.
Horizonal silhouettes were 'captive carry' flight tests, where the NB-52 lauch ship carried the X-15 for system tests without releasing it.
Tilted silhouettes were airdrops. Angled downwards were unpowered glides; angled upwards were powered flights.
Since the NB-52A (52-003) and NB-52B (52-008) were used together, the number of launches on the side don't correspond with the actual sequence of launches - '03 carried 93 of the X-15A's powered flights, while '08 carried the remaining 106. However, the exact order of the first five missions immediately shows that the aircraft in this picture is NB-52A (52-003) since the first four missions were captive flights and the fifth the only planned unpowered glide of the X-15 program - the first five missions on NB-52B (52-008) were five horizontal red stripes for the test flights done with the inertial guidance system in a modified F-107 external fuel tank mounted on the launch pylon.

Thank you!

If you read them you learn a new shout
el_ochaso@reddit
These are the mission sortie markings, I believe. All the different types of launch vehicles launched by this particular B-52 have a corresponding mission symbol painted on the aircraft. Im sure somebody more knowledgeable will chime in with more specifics.
