Right...loss of attitude control likely means the satellite will fail in its mission, but has little to do with when and where it will burn in, or whether it will hit some other satellite. It just joins the several thousand tons of broken-down crap already up there.

The author of TFA would seem to be thinking in airplane terms, which I suppose is a narrow cut above a car analogy...

Great example would be German museums dealing with the events surrounding their involvement in the World Wars and the Holocaust. You go into any of those, and while they talk a lot about the Nazi Party, National Socialism, Hitler and the rest, you would be hard pressed to say that anyone would think any of it is an endorsement. Everything I saw really had a tone of: "My God, we screwed the pooch BIGTIME. Let's put this all out here, so maybe people won't let it happen again"

Indeed. I was quite surprised to hear the tour guide at Hitler's mountain chalet above Berchtesgaden...she told it like it was, no beating about the bush. Her sentiment was clearly Nie wieder.

Eons ago there was a magazine called Softside that published games written in BASIC for the Apple II, Atari and TRS-80. It soon got a visit from a Radio Shack lawyer asserting that only Tandy had the right to publish software for their computers, and demanding that they cease and desist from saying "Radio Shack" or "TRS-80" in their articles unless they paid Tandy a royalty.

The magazine complied by saying "S-80 Bus" which was not within the scope of Tandy's trademarks. Tandy got its wish: nobody ever writes about Radio Shack computers today.

...a simple DC motor. It delivers its max torque at zero speed. However, you couldn't use just any old motor: in the "stall" condition it also draws maximum current, and most motors aren't designed to take the resulting heat load for more than a few seconds. One way around this would be operating the motor at less than its rated voltage.

If you "back-drive" a DC motor, you'll actually have to apply more than the stall torque, but if you're turning it at a speed much less than the free-running speed it will only be a small increase.

Voltage/current/torque relations for DC motors:

It is pitiable how the editor(s) feel the need to mock the ignorant propaganda of a thoroughly subjugated people.

I sorta got the impression that they were mocking the Caligula of the Far East who's doing the subjugating. The US gubmint isn't going to remove him, because he doesn't have any oil, so this is pretty much all we can do.
