One reasonable answer would be we don’t know. That would be consistent with our normal concept of criminal justice, there has not been any trial, all people except Republicans are considered innocent until proven guilty. Joe Biden has bragged publicly that he forced the Ukrainians to fire the prosecutor. Depending on…

If it is possible to do any of it at all, there might be places where it would be easier and other places much worse - the mountains on the way to California, assuming California still exists, are a lot bigger than the ones in the east, maybe too much to tunnel under. We could avoid some of that in New York by going…

Seems reasonable, higher speed will enable them to fly higher, coasting along on their kinetic energy - when they get up so high that there isn’t enough air for the engine, there also won’t be much air resistance to impede their progress - i.e., there is already plenty of vacuum without pumping, if we just go up to…

Right, the big advantage of vacuum seems to be reducing operating cost by reducing air resistance. Hydrogen would, as noted, reduce the power required even more, and it can’t burn as long as no air leaks in, but of course everything leaks. And leaks, of course, mean we can’t just pump out the air and stop, we have to…

Thanks for including my comment. It took a while to find it (had to look in the pending section, and the whole process of searching goes a lot better with those included, for some reason (hope that helps)) and I wondered if it had been left out because of my irreverent attitude that It’s Only a Game :-) But it is…

Let’s not forget, as LPR says, It’s Only a Game. The conflict of interest here is not nearly what it would be if he moonlighted to promote one team over another, he is promoting the sport in general in both jobs. And any damage he might do is minor league compared to the supposed journalists who work full time…
