IPCRESS posted:Not directed at you, but your post raises an interesting question: how much overengineering has been taken out of planes since slide rules gave way to supercomputer finite element analysis? How much of the margin of safety been shrunk by virtue of better design and notionally more repeatable manufacture? Would this sort of thing not be an issue in a 727 but kill 787s? It should just result in reducing inefficiency due to over designing. You still test to the same levels. Occasionally it may cause you to under design the system due to poor models but again, should be caught at test. This really is the difference between having a design and having a qualified design. The latter has gone through a qualification regime where the factors of safety, often 2x, have been rigorously demonstrated. The next step is continuous screening to show that process issues have not resulted in altering the design away from what was qualified during manufacturing. This is often supplemented by an acceptance test where you test to (but typically do not exceed) mission levels for each piece of flight hardware. And now you know why flight hardware costs an order of magnitude more than you would expect.

How much of the margin of safety been shrunk by virtue of better design and notionally more repeatable manufacture? Would this sort of thing not be an issue in a 727 but kill 787s? Safety factors exist because engineers know they don’t have a perfect understanding of the world. You imagine that big margin saving the day when atrocious alloys strike, but it’s just as likely that the margin will have been eaten up by something like “the rocket is vibrating like a pogo stick and we didn’t know that would happen”. If the metal is deficient on top of that, the rocket will fail. When the conditions are more fully understood, engineers can see where danger had been overestimated and where it had been underestimated. Good models give engineers confidence to economise overbuilt areas so as to reinforces areas where the safety factor was the only thing holding the ship together.

It is hardly possible to overstate how dumb Trump is. However, I don’t want to read about him being dumb, so that’s a hard pass from me. I would have written Forty Five out of the picture by having him choke on a pretzel or letting his advisors run the show—which I believe is more realistic anyway.

Tyndall still really hosed up. Something like 1.2+ billion dollars for hurricane/flood repairs. The fact that most of Tyndall's ~30,000 acres of trees looks like this is also expensive, as you kind of have to deal with it lest it become a big festering fire hazard.

The Insinna interview linked on the last page was both great and lead me to this interesting thing: https://www.defensenews.com/air/2018/08/27/us-air-force-tests-base-in-a-box-in-poland-to-prep-for-future-wars/ Defense News posted:KRZESINY, Poland — If the U.S. Air Force finds itself in a conflict with Russia, it won’t be able to simply rely on its major operating hubs in Germany, Italy and the United Kingdom. So it’s getting more expeditionary thanks to a new “air base in a box” that will enable the service to rapidly move to a partner nation’s airfield, set up a squadron and begin flying combat missions.
