NatGeo documentary follows a cutting-edge undersea scanning project to make a high-resolution 3D digital twin of the ship. //

In 2023, we reported on the unveiling of the first full-size 3D digital scan of the remains of the RMS Titanic—a "digital twin" that captured the wreckage in unprecedented detail. Magellan Ltd, a deep-sea mapping company, and Atlantic Productions conducted the scans over a six-week expedition. That project is the subject of the new National Geographic documentary Titanic: The Digital Resurrection, detailing several fascinating initial findings from experts' ongoing analysis of that full-size scan. //

The joint mission by Magellan and Atlantic Productions deployed two submersibles nicknamed Romeo and Juliet to map every millimeter of the wreck, including the debris field spanning some three miles. The result was a whopping 16 terabytes of data, along with over 715,000 still images and 4K video footage. That raw data was then processed to create the 3D digital twin. The resolution is so good, one can make out part of the serial number on one of the propellers.

"I've seen the wreck in person from a submersible, and I've also studied the products of multiple expeditions—everything from the original black-and-white imagery from the 1985 expedition to the most modern, high-def 3D imagery," deep ocean explorer Parks Stephenson told Ars. "This still managed to blow me away with its immense scale and detail."

In Winston Churchill: The Roaming Lion, a six-hour course, Dr. Larry Arnn examines Winston Churchill's life, philosophy, and political legacy through a comprehensive analysis of his military experiences, leadership principles, and views on governance. The lectures explore Churchill's evolution from a soldier-writer to a statesman, highlighting his perspectives on warfare, democracy, and individual liberty, while examining how Britain's geography and history shaped his strategic thinking. The course delves into Churchill's complex political philosophy, including his approach to just war, constitutional government, and the balance between social welfare and individual freedom.

Remember that free trade with China, allowing it into the World Trade Organization, was in pursuit of a foreign policy agenda. The thinking was China would move toward democracy, become a stakeholder in the international order.

That didn’t happen. It was a failed experiment. So all those jobs lost with the goal of liberalizing China were for nought. So if we’re still dealing with an authoritarian regime engaged in a mercantilist policy, complete with currency manipulation - it’s time for the USA to try something else.

In 1945, six women pulled off a computing miracle.

They programmed the world’s first computer—with no manuals, no training.

Then, a SINGLE assumption erased them from tech history for decades.

The story of how ONE photo nearly deleted computing’s female founders: 🧵

Kathy Kleiman, a young programmer, found old photos of women standing beside ENIAC—the first general-purpose computer.

When she asked who they were, curators said: “Probably just models”...

But Kleiman had a feeling they were something more:

Program ENIAC—a machine the world had never seen.

It was 8 feet tall, 80 feet long, and weighed over 60,000 pounds.

The engineers built the hardware...

But someone had to figure out how to make it do anything:

They were the world’s first programmers.

First, they were hired as “human computers” to calculate missile trajectories during WWII.

Then chosen for a top-secret project unlike anything before:

Security restrictions kept them out of the ENIAC lab.

They had to write programs using only blueprints and logic diagrams.

No manuals. No programming languages...

So how do you code something no one’s ever coded before?

By inventing the process from scratch.

They built algorithms, flowcharts, and step-by-step routines—on paper.

Then, once granted access, they programmed ENIAC by physically rewiring it...

And that’s where things got even harder:

There was no keyboard.

Programming meant plugging thousands of cables into the right configuration—by hand.

It was almost impossible to program.

But they pulled it off anyway:

The Titanic didn’t sink the way you think.

J.P. Morgan had a first-class ticket on the Titanic.

But he canceled at the last minute.

His biggest financial rivals stayed onboard—and never made it back.

Here’s the truth about the ‘unsinkable’ ship:

J.P. Morgan was the power behind the White Star Line.

At the time, he was consolidating control over the U.S. financial system through the creation of the Federal Reserve.

Three of the biggest opponents to the Federal Reserve were aboard the Titanic:

1. Benjamin Guggenheim (mining magnate)
2. Isidor Straus (co-owner of Macy’s)
3. John Jacob Astor IV (one of the richest men in the world)

All three opposed Morgan’s plans for the Federal Reserve.

None of them survived.

Meanwhile, J.P. Morgan had a first-class ticket on the Titanic—but canceled his trip at the last minute.

In 1985, researchers discovered the Titanic wreck.

But when they examined the hull, they found something shocking:

The metal plating was bent outward. //

3. Three of his biggest rivals died aboard

4. There are serious discrepancies in the Titanic’s construction, sinking, and insurance.

Coincidence? Maybe.

Or maybe one of the greatest financial schemes in history.

No one can prove the Titanic was deliberately sunk.

But here’s what we do know:

1. J.P. Morgan controlled White Star Line

2. He canceled his trip at the last minute

3. Three of his biggest rivals died aboard

4. There are serious discrepancies in the Titanic’s construction, sinking, and insurance.

Ninety-nine years ago, H.L. Mencken - the "Sage of Baltimore" - released his book, "Notes on Democracy," which I really need to go read again. Mencken was no fan of big government, even by the standards of the 1920s; in fact, you could argue that he was no fan of government at all. What's interesting about his work is his prescience.

Granted, society and politics run in cycles. The Strauss-Howe Generational Theory is one attempt at defining these cycles. So is the old saw that goes, "Tough times make tough people; tough people make good times; good times make weak people; weak people make tough times." //

Mencken. He wasn't an optimist. But when you read his work, you wonder if he didn't have some kind of premonition as to what's going on in the United States today. Back then, in the Roaring Twenties, Mencken made this observation:

The ideal government of all reflective men, from Aristotle onward, is one which lets the individual alone – one which barely escapes being no government at all.

Good government is that which delivers the citizen from being done out of his life and property too arbitrarily and violently – one that relieves him sufficiently from the barbaric business of guarding them to enable him to engage in gentler, more dignified, and more agreeable undertakings.

In other words, the only legitimate role of government is to protect the citizens' liberty and property. //

The notion that a radical is one who hates his country is naive and usually idiotic. He is, more likely, one who likes his country more than the rest of us, and is thus more disturbed than the rest of us when he sees it debauched. He is not a bad citizen turning to crime; he is a good citizen driven to despair.

The most dangerous man to any government is the man who is able to think things out for himself … Almost inevitably, he comes to the conclusion that the government he lives under is dishonest, insane and intolerable.

All government … is against liberty.

I believe in only one thing: liberty; but I do not believe in liberty enough to want to force it upon anyone. //

"The most dangerous man to any government is the man who is able to think things out for himself …"

This was true in ancient times; it was true in 1926; and its true today.

Unlike almost every other country, the US was founded on rebellion- people thinking for themselves and resisting the pressure to obey the government for the sole reason of "because we tell you to."

There are those who hate this quality and actively push against it with their NewSpeak and pronouns and "canceling".

I hope we will always have the rebels, who think for themselves and resist the conformity.

My favorite Mencken quote: "Every normal man must be tempted, at times, to spit on his hands, hoist the black flag, and begin slitting throats." Not sure quite why I love it. I just do.

On this day in 1975, Bill Gates and Paul Allen founded a company called Micro-Soft in Albuquerque, New Mexico.

It has been about a year since we reported on the major revelation that many thousand original North American Aviation manufacturing drawings survived destruction during the 1980s because one of their employees, Ken Jungeberg, saved them from incineration. Furthermore, as we also discussed last year, AirCorps Aviation worked out a deal with Jungeberg in 2019 to secure these historic artifacts for their longterm preservation. Ever since their arrival at AirCorps last winter, Ester Aube, the company’s manager for their technical documentation division, AirCorps Library, has been working diligently to preserve and catalogue this massive archive. With so many drawings to review, this would be a daunting task for anyone to undertake successfully, but Ester has applied her keen intellect, professional training and substantial skillset to systematically document and collate these drawings into a practical and valuable resource for aircraft restorers, historians, and the aviation-minded public at large. Additionally, Aube has delved deeper into the process, tracing personal details for several NAA technicians who originally drafted these drawings, because their stories are no less important to the narrative than the documents themselves; this aspect of aviation history has received little prior attention from the wider world …until now.

AirCorps Aviation of Bemidji, Minnesota has just announced that they have acquired a massive trove of original manufacturing drawings for North American Aviation (NAA) covering types such as the P-51, T-6, B-25 and P-82. This is a remarkable development, and all due to a lone engineer at NAA named Ken Jungeberg who had the foresight to save these drawings when they were days away from destruction at North American’s plant in Columbus, Ohio during the late 1980s. But before we discuss this find, it is perhaps first worth reflecting upon what it represents…

Just a few of the thousands of WWII-era North American Aviation aircraft manufacturing drawings which Ken Jungeberg saved. (image via AirCorps Aviation)

The American aircraft industry produced just under 300,000 aircraft between 1940 and 1945, a staggering feat by any measure, especially considering that just 3,600 rolled off U.S. assembly lines during the entirety of 1940. While aviation companies such as Boeing, Douglas, Curtiss and their like would design the aircraft, and put them together at their factories, it was simply impossible for them to both make all of the components and subassemblies on site and keep up with production demand. They had to subcontract out the bulk of this work once a design received an order for full-scale production. Indeed, much of America’s entire manufacturing base was involved in this effort – from small ma and pa furniture shops to industrial giants like Ford and Chrysler – whether they were making map cases or wing panels. Some companies, such as Ford, even had their own aircraft assembly lines, like the one in Willow Run, Michigan which built B-24 Liberators.

But have you ever wondered how it was possible to have such a prolific output of high quality aerial machinery when each aircraft assembly line received component parts from so many different independent subcontractors? How was it possible for all of those many thousands of parts to fit together properly in such a repeatable fashion?

The answer is pretty simple; it all came down to the quality of the manufacturing drawings which the aircraft company engineers created during their design process. If you had a coherent set of accurate drawings showing how to make each part, and how to put each assembly together, then you could rely upon skilled workers at disparate factory locations to produce components whose dimensions complied with design tolerances. Of course, there were times when problems arose, but when they did, the engineers usually found solutions. But a coherent set of manufacturing drawings was key to this effort.

However, every single component, from the tiniest rivet to the entire aircraft, required drawings to properly describe them. Obviously, the more complex parts and sub-assemblies required multiple drawings, sometimes hundreds. Highly skilled draftsmen and women created all of these drawings by hand by – usually using pencil on vellum drafting paper. Drawings could sometimes be massive too, extending ten feet or more. The finished product was designed to be practical, fully describing the part and how it fit into an assembly. Drawings were often exquisitely beautiful too – more works of art than simply functional. //

But then along came AirCorps Aviation with their AirCorps Library project. For a small annual subscription of just $50, you have access to serious engineering details, including manuals, for several dozen American WWII-era aircraft designs. They have also digitized the engineering drawings for a number of these aircraft too, such as the P-51 Mustang, F4U Corsair and B-17 Flying Fortress. While they haven’t digitized everything available yet for each aircraft design – it’s a massive process – it is a fascinating resource for anyone with even a passing interest in WWII aviation. //

This is why the news about the preservation of more than 15,000 original drawings produced by North American Aviation that relate to such iconic designs as the T-6 Texan, P-51 Mustang and B-25 Mitchell is such a revelation. AirCorps Aviation has gained access to these drawings, and is presently cataloguing and copying them for their subscription library. However, the fact that these drawing still exist at all is down to the dedicated efforts of just one man, Ken Jungeberg. His name will resonate in aviation lore for generations to come due to his foresight in saving such historically important documents. For further details on this remarkable news, we will let AirCorps Aviation’s Ester Aube continue the story…

Thousands of original North American Aviation technical drawings undergo preservation and cataloguing, highlighted in museum exhibit. //

In April of 2023, Ester Aube finalized and installed an exhibit at the EAA museum using the drawings and telling the story of the draftsmen from North American and highlighting their contribution to the war efforts. When the collection was initially received from Ken Jungeberg, they had promised to do something to help get the story of the draftsmen out to the general public and get some of the drawings in public view so that people could enjoy and learn. The exhibit will be in the museum until September of 2025. “I chose some, cherry-picked some really amazing drawings to highlight in that exhibit,” says Aube. //

With so many drawings and aircraft to sort through, Aube started the project working on a specific aircraft, the P-51, because both AirCorps Aviation and the many aircraft in the warbird community would get a lot of benefit from such extensive original engineering drawings. At this point she estimates she has catalogued a little over 15,000 drawings just for the Mustang, and has also ventured into the smaller size drawings for the early B-25 models, which will be her next branch to catalogue. “The cataloging process is very labor intensive,” she says. “So I’m cataloging part number and the description, which under normal circumstances isn’t as important. But because this collection contains so many experimental and pre-production drawings, you have to catalog the description because that part number isn’t listed anywhere in a parts catalog or it’s not referenced.” North American did have a part numbering system, but all the pieces of data are needed or else the searchability is difficult. So part number, description, the date it was drawn, name of the draftsman, the material the drawing was done on, and the factory it was made in all are recorded during the cataloguing process. There are drawings from factories in Inglewood, Kansas City, Dallas, and even some from the Canadian Car Foundry in Ontario, Canada’s largest aircraft manufacturer during World War II.

Ken Jungeberg’s efforts saved a vast collection of North American Aviation’s WWII engineering drawings from being lost. In this interview, Ester Aube of AirCorps Aviation shares his story and her role in their preservation. //

During World War II, long before the advent of computer-aided design, thousands of skilled draftsmen meticulously created tens of thousands of engineering drawings for every aspect of each aircraft model produced. These drawings were not only precise and detailed—ensuring different factories could manufacture components to exact specifications—but also works of art in their own right. Without the dedication of preservationists and archivists, many of these irreplaceable documents might have been lost forever. Thanks to the vision of a select few, however, these drawings are being safeguarded—not just as historical artifacts but as invaluable resources for the warbird restoration community. In 1988, Ken Jungeberg, head of the Master Dimensions Department at North American-Rockwell’s Columbus plant, was granted permission to save a large collection of non-current engineering drawings from the company archive. //

Re: Loud printers
You've obviously never used an ICL 1900 lineprinter: these could print at 160 characters per line at up to 1300 lines per minute. The mechanism was based round a hollow drum the full width of the paper with 160 rings of characters, each containing the complete character set. These were organised so that each embossed row had the same character in every position. The embossed drum was installed behind a row of 160 hammers and a inky ribbon the full width of the paper: both paper and ribbon scrolled vertically, though not at the same speed. The print hammers were driven off a very latge capacitor in the printer's body.

The printer was loud enough when printing invoices, etc, but George 3's print driver could easily outdo it. It separated documents by outputting, IIRC, a page throw, a job title, 10 full width lines of 160 asterisks and another page throw: when this happened the printer almost jumped off the floor and made a noise similar to a short burst from a machine gun.

These ICL printers were much louder than any IBM lineprinter I've ever heard running. That's because IBM used train printers: the character set formed a rotating chain running across the paper path and were designed so that only one character could hit the paper at a time. //

Re: Loud printers
Impact printers were getting fairly close to their practical limits in terms of printing speed. There was a flurry of development in the early 1970s to come up with better solutions. Xerox produced something that was kind of a hybrid between a drum printer and a photocopier - a set of flash lamps illuminated the correct characters on a drum transferring their images optically to the selenium copier drum. That got printing up to around 4000 lines a minute. Honeywell introduced an electrostatic system using a dielectric paper that raised speeds to 18,000 lines per minute.

However, it was IBM that developed the first laser printer - the IBM 3800. Its initial version managed only a shade under 14,000 lines per minute, but a later version raised the speed to over 20,000 lines per minute - around 2.8 km/h. With paper running that fast , a laser and a hot fuser unit, suddenly noise was not the only hazard. There's a fascinating training video for operators that shows the massive scale of the beast.

Francos said the order to release the files came directly from the president, and it would be part of a larger Milei project to declassify and release information about the 1970s military crackdown on government opponents, many of whom disappeared.

The government announcement came on March 24, which in Argentina is a public holiday to commemorate the victims of the political strife during the so-called Dirty War. The Dirty War ran roughly between the 1974 death of President Juan Peron and the subsequent 1976 military coup, through to the junta’s fall in 1983.

Peron, who was sent on a 1939 mission to learn about Italian fascism, is an essential figure in the Nazi migration to Argentina. He was a senior member of the fascist government coup that took over the country in 1943. That government declared war on Germany in February 1945, which could be seen as a fig leaf for its true leanings.

In a 1969 interview with historian Felix Luna, quoted by Tomas Eloy Martinez in his Wilson Center paper, “Peron and the Nazi War Criminals,” Peron said he reached out to influential members of the German community to explain that the war was over and Argentina needed to act. “Please understand, we have no choice but to go to war, for if we do not, we will go to Nuremberg.”

Eloy Martinez said Peron told him in 1970 that he orchestrated the effort to collect as many worthy Germans as possible—just as the United States, Russia, England, and France were doing—and because they were technically on the winning side, they would have a free hand.

Peron, who began his first of three presidential terms in 1946, also said he coordinated with Spain’s Generalissimo Francisco Franco, who had remained formally neutral throughout the war.

Every year, nearly 1 million new citizens are welcomed into the United States through naturalization ceremonies, all of whom must pass the American citizenship exam by answering 6 out of 10 questions correctly.

The document is about Gary Underhill, a CIA special assignments operative who dropped a major bombshell the day after Kennedy's assassination. This wasn't some conspiracy theorist in a tin foil hat—Underhill was a World War II military intelligence veteran and former Life magazine photojournalist who was linked to high-ranking CIA officials.

On November 23, 1963, a clearly disturbed Underhill made a desperate journey from D.C. to New Jersey to warn friends about a "small clique within the CIA" being responsible for Kennedy's death. A memo with the subject line "Ramparts" (the name of a magazine that featured investigations of the CIA) notes that friends described him as "sober but badly shook."

This is quite telling for someone who was a "perfectly rational and objective person," as his friends described him. //

Less than six months later Underhill was found shot to death in his Washington apartment. The coroner ruled it suicide. //

Underhill claimed Kennedy was about to “blow the whistle” on a corrupt CIA faction involved in “gun-running, narcotics, and other contraband.”

Although the friends had always known Underhill to be perfectly rational and objective, they at first didn't take his account seriously. “I think the main reason was,” explains one friend, “that we couldn't believe that the CIA could contain a corrupt element every bit as ruthless—and more efficient—as the mafia.”

Now, here’s where things get weird. Underhill was found dead months later with a bullet in the left side of his head.

The verdict of suicide in Underhill's death is by no means convincing. His body was found by a writing collaborator, Asher Brynes of the New Republic. He had been shot behind the left ear, and an automatic pistol was under his left side. Odd, says Brynes, because Underhill was right-handed. //

I always wondered about Jack Ruby killing Oswald while he was being transferred from the jail. Ruby was a night club owner deeply in debt to the Mafia bosses. Would a grown man with his lifestyle be so "heartbroken" by the death of the president waltz into an apparently unrestricted police area to kill the assassin?. I guess life in prison was preferable to the punishment of not following Mafia orders to shut up Oswald. I remember seeing it live on TV as my father, a NYC cop, jumped up and screamed "He's got a gun"!!!
