What, back to my old job as Space Relay Designer?Ouch!
There was a recent article in the Seattle Times about a brain drain of experienced engineers out of the company. Maybe they can get Ron W. to come out of retirement?
What, back to my old job as Space Relay Designer?

"It blocked my view of Venus!"I thought you worked on the Illudium Q-36 Explosive Space Modulator?What, back to my old job as Space Relay Designer?
We have a biweekly Zoom meeting of retired space guys from my particular area. One of the theories bandied about is that an umbilical took a lightning hit and scrambled the electronics.Making valves out of a material that don’t corrode in the presence of Water and rocket fuel doesn’t seem to be a major challenge……..but I’m not a Rocket Scientist, just a plane old aircraft and engine engineer
This sums it up nicely… too many players
“The SpaceX success seems even more impressive considering that SpaceX’s Dragon capsule sits atop SpaceX rockets with engines built by SpaceX.
The Boeing Starliner capsule sits atop a United Launch Alliance, or ULA, rocket. Some of the engines are made in Russia, while others come from suppliers such as Aerojet Rocketdyne (AJRD).”
On the other hand, we were frequently locked into antiquated releases of vendor software supporting legacy programs so that we didn't have to revalidate tools and legacy code, which was particularly important with a vendor that like to change intrinsic functionality drastically between releases. Imagine calling vendor tech support(*):However, the German and Spanish partners didn't have the most up-to-date version, and they were loath to spend the money to upgrade. The two versions weren't completely compatible. They brought political pressure... the German president contacted the French president, and the pressure was applied to Airbus. They didn't HAVE to upgrade.
Yup. An answer to many E-AB newbies that want to design their own homebuilts with fly-by-wire and other such stuff. Or hydraulic controls. Somehow, cables and pulleys, or push-pull tubes, are SO old-school.Worst thing is an over engineered solution to a simple problem.

I contend that an under-engineered solution is just as bad. EAB is a good source of examples there, too.Yup.

At times, it seems like Jefferson Starship will reach orbit sooner than any post-Shuttle US program.There was a joke that Starship would reach orbit sooner than this Starliner. Now it's no so much of a joke.
I'm sure they got very high a very long time ago....At times, it seems like Jefferson Starship will reach orbit sooner than any post-Shuttle US program.
Saw a great example of that about 25 years ago. Company we were working with needed a mechanism to open a solar array. They had all these snubbers and energy absorbers and this and that to make the opening as gentle as possible. Our chief designer maligned it as "something suitable to open the trunk of a British car."Worst thing is an over engineered solution to a simple problem.
Most great designs come from small teams, where the goal is consistent and the design is gradually tweaked. As a mechanical example of that, John Browning. Software, lots of examples, one being Linus Torvalds. What companies today seem to do is have really large teams, and continually change the goals, calling it "rapid development" or some nonsense.
Reminds me of my days on Senior Trend (F-117), Tacit Blue and other things unnamed. I demanded the same thing on the YF-22/YF-23 Program when I had the stick.Hey, it worked for the Klingons...

We used the term "Rapid Prototyping" in our neck of the woods; did the first program in the '90s. I helped write a Boeing rapid prototyping guide. Used the process successfully for several sequential programs, with a number of satellites deployed. Last one put multiple satellites on orbit for less than $10M (not including launch, but we got a free ride on an X-37B). Development time, from scratch, was one year (waited longer for the ride).
It's tough to do what's necessary to accomplish this in a big company like Boeing. The first program in the '90s, we were really, REALLY isolated from the company as a whole. Even our IT guys were independent. If we needed a new computer, the IT guys took the program credit card and went to Circuit City. While there was squawking within the company, we always had 100% buy-in from our Government customers.
Toward the end of my career, we were losing some of that kind of independence. Most of it was due to the Boeing/MacDac merger. Our upper management chain now terminated out of state, and hell hath no fury like a mid-level manager who is told, "Sorry, we're not going to tell you what we're doing..." Helped that they couldn't access our files/information from California (no network connection at the appropriate security levels).
The only way we got this done, as Thought-Captain K'anttiah says, was due to secrecy. We had legitimate reasons we couldn't tell manager so-and-so what we were up to. The Government was doling out access with an eyedropper, and we needed more engineers, not managers.
Best thing about it is that we worked *with*, not against, our Government customers. We set up a small area right in our work zone, and always had Government reps on-site who were welcome in ANY meeting, any testing, knew the same time we did when a problem occurred, etc. Not only did this foster a sense of teamwork, but it was an outstanding opportunity for young lieutenants and captains to get hands-on experience actually BUILDING something, rather than evaluating quarterly reports.
Now, Starliner is a lot bigger, and I suspect many of our techniques wouldn't be applicable.
