The triumph of the squares


The 50th anniversary of the first moon walk has caused me a full-blown geek-out. I remember the space race with fondness. Aerospace was the biggest story out there. The 50s and 60s saw an explosion of technological growth. Some favorites of mine from that era include the F-104, the U-2, the SR-71, the Boeing 707, 727, and 747—the "jet age" planes that changed travel and even music by democratizing flight.

I "graduated" from my Erector Set stage straight into model airplanes—the ones that flew and made a bunch of noise. And even though the space race was on, I was never seduced into model rocketry. It was expensive and the available examples didn't do much—restricted as they were by the same sort of regulations as fireworks (which where I lived were essentially outlawed.)

Real-world rockets were kind of boring as well. The most notorious of the test pilots out at Edwards Air Force Base (Chuck Yeager) even labeled the early astronauts as nothing more than "spam in a can." After all, the first "American" in space was a chimp. But that wouldn't last long. The original astronauts were extremely competent test pilots and before long, they were demanding greater control of their missions.

Even so, I was far more interested in the flight testing at Edwards where they pushed the limits of supersonic flight with real airplanes like fighters jets. But soon, they eventually embraced rocketry with the incomparable X-15. They had to. If you want to set speed and altitude records, eventually you run out of atmosphere where air-breathing power-plants simply do not work. The X-15 was insanely fast, complex and dangerous. It wasn't going to be piloted by a chimp. In fact, these things required the skills of the best pilots we could find. And I had a favorite—Neil Armstrong.



Armstrong was a superb pilot. On one mission a failure of a new instrument caused him to fly nearly 50 miles beyond where he was supposed to turn back to Edwards. His propulsion was spent so he was flying a glider with the aerodynamic performance (4:1 glide ratio) of a brick. He nursed that X-15 back to Edwards coming over the lake bed at less than 100'. This would be the same guy who landed on the moon with less than 30 seconds worth of fuel.

His degree in aeronautical engineering came from Purdue. This is NOT a school that grants engineering degrees to goof-offs. In fact Purdue would contribute a serious fraction of the top engineers to the space program. The rest mostly came from State Universities in the USA Midwest like Michigan.

He grew up in Wapakoneta, Ohio about an hour north of Dayton—the home of the Wright Brothers. His father paid for a ride in a Ford Tri-motor at 6. He soloed an airplane on his 16th birthday (the legal minimum age) and spent much of his childhood building model airplanes. This last fact is what endeared him to me. I too built model airplanes which were insanely difficult to get to fly well. The problem is that models and real airplanes conform to the same laws of nature which means to indulge in this hobby, it really helps to learn things like fluid dynamics, lightweight structures, and drag coefficients. You know—kid stuff.

Yes that is me with a model that required at least 150 hours to build. Didn't fly very well—too little power and too much paint.



Flying is something that only happens on the boundaries of perfection. You can get 15,000 things right and one wrong and your precious airplane is a flaming heap. Good pilots are followers of check lists—as diligent on the 1000th time through as the first. They read the operator's manuals. They know what all those switches do. They understand that dishonesty and corner-cutting could end their lives.

Armstrong was notorious for insisting on understanding every part of his aircraft. He wanted to know what everything was supposed to do and what it COULD do in an emergency. But even better, he understood that flying is a team effort and it was critical for every member of the team to take their jobs seriously. Here's what he says about the people who built Apollo.
Armstrong: Each of the components of our hardware were designed to certain reliability specifications, and for the majority, to my recollection, had a reliability requirement of 0.99996, which means that you have four failures in 100,000 operations. I've been told that if every component met its reliability specifications precisely, that a typical Apollo flight would have about [1,000] separate identifiable failures. In fact, we had more like 150 failures per flight, [substantially] better than statistical methods would tell you that you might have.

I can only attribute that to the fact that every guy in the project, every guy at the bench building something, every assembler, every inspector, every guy that's setting up the tests, cranking the torque wrench, and so on, is saying, man or woman, "If anything goes wrong here, it's not going to be my fault, because my part is going to be better than I have to make it." And when you have hundreds of thousands of people all doing their job a little better than they have to, you get an improvement in performance. And that's the only reason we could have pulled this whole thing off.

The Triumph of the Squares

Nearly a year after the landing of Apollo 11, NASA head Thomas Paine gave a commencement address at Worcester Polytechnic Institute where he declared that the successful moonshot was a triumph of the squares, the validation of the values of "Squareland" which he listed as foremost a profound faith in reason. It was "outward looking and mathematical," was "time oriented...and deeply concerned with future consequences." It "accepts as true only rational facts and theories which predict future events with mathematical precision under rigorous standards of reproducibility. Only Squareland's rationality could ensure the "crops yield, lights light, bridges carry loads, children avoid polio, and men walk on the moon." In fact. to Squarelanders, a solid definition of "truth" might be "that which successfully takes two men to the moon."

This speech made me groan and roll my eyes. On one hand, going to the moon really DID require the "square" virtues that Paine so celebrated. Beside, I was clearly a prototypical "square" (see photo above.) Building airplanes sort of demands squareness. I was also the son of a small-town clergyman—building airplanes was one way of staying above the reproach of the church ladies. On the other hand, this speech set off the scolds who assumed that "square" virtue included an unquestioning support of the Vietnam War, a marked preference for booze over pot, white shirts and neck ties, and above all, short hair for men.

Unfortunately, the space race had been sold as Cold War macho and a real-live Nazi named Wernher von Braun was chosen to head the effort. So the link between the space race and unbridled militarism was pretty damn short. NASA was acutely aware of this problem. It was one of the reasons that Neil Armstrong was chosen to take the first step—he was the only civilian pilot to have reached his advanced status. This turned out to be an excellent choice. In the goodwill tour following the moon landing, he charmed his listeners around the world into believing that this was a triumph of human (not American) genius. The reason this worked is because Armstrong deeply believed it was true.

But while the moon landing was clearly a triumph of the squares, the squares would not triumph. By 1972 the Apollo program was ended and no human has gone beyond low-earth orbit since. The can-do attitude of Apollo has so completely disappeared from American culture that many now actually believe the landing was a hoax. It is probably more accurate to call Apollo "Peak Square" because the vast majority of my fellow citizens in 2019 look on a profound faith in reason as a weird psychological disorder.

BBC calling

In the summer of 1970, I found myself in UK. I kept running into people who wanted to talk about the moon landing. Most of them were very well informed. I had to scramble to keep up at times. One night in London, a waitress in a pub sat down next to me and asked if I was the American space expert she had overheard. I humbly admitted I was probably who she was looking for but I was FAR from being an expert. Then she asked, "How did they know how long the burn for the lunar insertion midflight correction should be? And how did they know they were pointing the engine in the right direction?" I didn't have a canned response so I pulled out my understanding of inertial navigation. It wasn't a very good answer but she seemed to understand, smiled and went back to work. I was left wondering just how a random London barmaid knew enough to even ask such good questions.

In 1978, PBS would air a 10-part series called Connections starring a fascinating storyteller named James Burke. (There was a companion coffee-table book by the same name). Burke had carved out an awesome assignment for himself. He wanted to explain the products of the modern world (computers, plastics, powered flight, etc.) in such a way that his listeners would understand how their world came to be. It was absolutely brilliant. Episode #1 The trigger effect traced the development of a modern city like New York back to the invention of the plow. The nine that would follow were equally good. Somewhere along the way we are informed that Burke was the man who covered Apollo for BBC.

AHA! That explained why the Brits knew so much about the moon landing—at least partly. So in the near-infinity of Apollo 11 at 50 coverage on YouTube, I went looking to see if I could find any of Burke's descriptions. I found a good one—an hour of Apollo highlights.




Just in case you need a reminder of how utterly lame the Apollo coverage was on USA corporate media, here is an example from ABC. I am pretty sure all the CBS and ABC coverage of the whole mission can be found at YouTube.

Of all the footage of the Apollo 11 mission that I have uncovered in the past few months, the following may be my favorite. It was done by NASA and has even more in capsule footage than the recently released Blu-Ray of Apollo 11. Of course, the new version has far superior imagery because restoration techniques are so much better. But this one is narrated by Wernher von Braun himself and the technique he used is to compare the 1969 effort against the description of a trip to the moon from Jules Verne's 1865 From Earth to the Moon.





As for the speculation that the Apollo program could provide a template for how this nation should take on the challenges of climate change, my responses are:

It might work
  • If we can restock our seriously depleted supply of "squares."
  • If we can find leadership that understands that this problem will be at LEAST 1000 times more difficult than the moon landing—and that's the best reason to do it.
The HILL looked at this possibility in more depth: Apollo as model for climate change.
