This has been a fun week for me, and I hope for all of you as well. I brushed up on my Star Wars trivia, and even if you aren't familiar with the movies, I hope there were enough scarf wearing ideas to allow everyone to participate. I'm going to finish this week with a few serious thoughts, and then some tidbits that didn't fit in elsewhere. Thank you all kindly for reading and participating.
As I watched the last of the eleven Star Wars movies, I thought back to what I found to be the overriding theme. Hope is often mentioned, but I was struck by the continued failures of the Empire in spite of their overwhelming might. Why were the Rebels able to succeed in defeating the Empire? I submit to you that their success was because they were able to identify a Single Point of Failure.
The history of aviation is littered with accidents due to a single point of failure, where there were no redundant systems in place to prevent disaster. A single point of failure, purposely put in there by the designer, was responsible for the success that Luke Skywalker had in destroying the Death Star in the original Star Wars movie. The story of stealing the plans to the Death Star for Luke is told in Rogue One: A Star Wars Story.
Apparently, the Empire did not learn from this epic failure. I rewatched The Rise of Skywalker, which is the final Star Wars movie, recently and was amazed that the Empire continued to design their star craft with a single point of failure.
(The Rebels: Hey, all we need to do is shoot at the highly vulnerable axial superlaser, and the entire planet-destroying star ship just blows up. Me (sarcastically): Wow, just wow!)

DH is a retired aeronautical engineer, and much of his career was spent worrying about possible failure in the flight controls of the aircraft he was working on, and fixing any issues during the design process. One of the planes he helped design was the BPJ. (I'm calling it a Big Passenger Jet for here.) I remember him coming home one day and saying that hackers had succeeded in getting into the flight controls of the BPJ and there was going to be a story on the front page of a prominent US newspaper the next day. (Big Yikes!!) I asked how did the hackers obtain a BPJ? (I mean, that is a big, expensive aircraft and who would let hackers play with their airplane?) He said no, they had hacked the controls systems software that was running on a Microsoft PC. (His company sold the software for use in flight simulators, which are used for pilot training.) I said, oh, everyone knows that you can hack a PC. I was certain that the aircraft was safe, because I knew how good the people who worked on it were. It took a night of frantic work by his company's engineers, but I was absolutely correct. The story ran, and since the hack would not work on an actual airplane, the story quickly died.
An example of an aircraft accident due to a single point of failure was the crash of United Flight 232 (a DC-10) in Sioux City, Iowa in July of 1989 after debris from a catastrophic engine failure in flight severed all the hydraulic lines which were bound together at one point. Miliary aircraft specifications at the time did not allow this, however it was allowed in civilian aircraft because it was argued that they would not be shot at. This single point of failure is no longer allowed.
A more recent example is the Boeing 737 Max, which was designed to have certain flight controls depend on the reading of a single sensor, which was already known to be particularly unreliable. Furthermore, the presence of this flight control software was new for this model and was not documented for the pilots. Clearly someone who had sufficient decision-making influence should have been worrying about what could possibly go wrong here, and wasn't. This system was involved in the crashes of Lion Air Flight 610 in 2018 and Ethiopian Airlines Flight 302 in 2019, and all 737 Max aircraft were subsequently grounded until it could be redesigned and recertified.
Thank goodness the Empire never figured out star ship redundant design a long time ago in that galaxy far, far away. Our continued difficulties with the single point of failure issue today shows that this problem is a constant threat. In looking at the inventions on Exposition Universalis, one must hope that they are well-designed and safe.

Moving on to a few final tidbits.
Goggles - Tusken Raiders were native inhabitants of Tatooine that had adapted to the harsh desert climate. Note the goggles, to protect the eyes from the harsh glare of the twin suns. The snow goggles on Le Regard de l'Arctique served the exact same purpose for the native Inuit peoples to protect the eyes in the harsh, icy white, arctic climate.

Cookies - What is this that Grogu is eating? Yeah, I'm pretty sure that it is a macaron. The scarf is La Patisserie Francaise.

Goldfish - How often do we see a mention of Star Wars in unexpected places? Say, in your supermarket snack aisle? Here are Goldfish crackers with Faubourg by Night. They are pretty tasty.

My scarf of the day is Le Regard de l'Arctique in celebration of the end of six months of snowy weather. Thank you for joining me this week in a look at Star Wars themes and our Hermes scarves. May the Force be with You!
