Comment Re: What happens to other MD11 pilots? (Score 2) 88

On the contrary, MD11 pilots have the most to learn about the automated systems. Just because its automated, doesnt mean you dint need to know how it works, when it works, what it looks like when itâ(TM)s not working, what you still get when it doesnt work, what you dont get when it doesnt work,â¦

Some of the worst Airbus crashes for example have been caused when the automation has suddenly degraded from normal law to either alternate of direct law, and the pilot has not understood that they now dont have the protections that they normally get, or have straight up lost control of the aircraft in the degraded state.

I think your idea of how fast subduction happens is a little off by some orders of magnitude.

However encasing it in something that won't leak (like glass) and dumping it in a very deep and dead part of the ocean is plausible and may be the best idea we have. There is no need to aim for the subduction fault, that makes no difference.

I think it's pretty hard to argue they haven't demonstrated rapid reuse. They've demonstrated that they can land, and reuse their booster, in later cases with very minimal refurbishment. They've demonstrated that they can land their ship. I don't see any reason why they shouldn't be able to reuse the ship. There's still an open question about the quality of the heat shield, but it's clear that it is improving rapidly with each flight, and is likely very close to being "good enough". The most recent ships haven't seemed to have (m?)any tiles fall off. They've had gaps when they've landed, but that's because they've had gaps when they took off, to test whether the ship can survive missing tiles during reentry.

As far as mass to orbit, yes, it's reasonably clear that they have a problem with the dry mass at the moment. That said, it's become reasonably clear that they understand how much of a dry mass problem they have, and therefore figured out how much larger the ship needs to be to solve that problem. Version 3 is clearly designed to solve the dry mass problem in two ways. 1) Adding a bunch of fuel. 2) Making the engines more powerful.

As you say, for Starlink, they're fine at this point, they can launch a bunch of satellites, they can reuse the booster. That's at least as good as Falcon 9. As far as tankering, it's clear that they're planning on starting tankering next year, again, with version 3. It's clear to me that that indicates that they think they have enough mass margin to be useful at that point.
