Are you a helicopter pilot? I thought you rotated with power out, just not as fast as you would without the tail rotor. I could be wrong... I only worked on the engines and used them as a passenger. I've only flown sail planes...

I mean, you do have some control during autorotation descent, but it's at best an extremely hard landing if your pilot is really skilled. They build crumple zones into the seat mounts for them.

It's a pretty cool technique. You adjust your rotor pitch to let you fall faster which let you put/keep angular momentum into your rotor, then at the last minute before slamming into the ground you pull hard on the collective and turn all that angular momentum in your rotor into lift to make it so that you don't slam the ground at full speed. You can manipulate the cyclic control (direction controls) during autorotation, but you're spinning the whole time, so it's very hard to guide an autorotation to a specific landing area.

I'm polyamorous. I won't even date someone who dates cops.

Even a well maintained helicopter is a safety nightmare.

I started my career in aerospace at a company that makes helicopter engines and later I became a search and rescue mountaineer/EMT in a county with more helicopters used for SAR than anywhere else in the US. We beat it into our new members "never pass up the opportunity to turn down a helicopter ride".

The mountain rescue association tracks member fatalities and injuries. Helicopter accidents are, by a large margin, the leading cause of line of duty death in mountain rescue, and we spend only a couple percent of our time in them.

I used helicopters a lot when I was on mountain rescue.

I never saw an air sick bag

It will always be a matter of "for how long?". Location from integrated acceleration is what we call a stiff problem. Meaning that any error is compounded as you continue to integrate (slight over simplification, but good enough for the point). There will never be a sensor that has zero error, so it's just a question of how much integration you can do before the errors make the results unusable.

Do you have a recommendation for a good cheap android phone (didn't worry, I'll run a rom) that one could get to have a "clean" phone?

I've been thinking about getting a phone that has none of my socials on it for when I go to Canada to get vaccines

Without GPS or tower based error correction any location prediction based on conservation of momentum in the phone will be useless before very long if the phone is moving.

Yes, but the point about minimizing plant deaths by eating plants instead of feeding more plants to animals and then eating the animals is a valid one...

The comment you link to does do a better job of explaining what you're getting at, but I would still argue that those behaviors also require a partitioning of empathy, and that is a behavior most humans are susceptible to... Those who have empathy can often be made to shut it down or partition it so that it only applies to certain people.

I stand by my original comment modulo the part that asserts that it is empathy. It is not a lack of intelligence being the point.

I don't think you understand what empathy is. Why are you bringing up irrational appeals to emotion?

Many of the Nazis convicted at Nuremberg were undeniably smart in the sense that they could perform abstract reasoning better than most people. Some of them had top 1% IQs and none of them had below average IQs (yes, IQ is an imperfect measure of intelligence, but at the same time, anyone who gets a 130 on an IQ test is smart... They just might not be smarter than someone with a 120 or a 110 from a different background).

I've had a long (25 years so far) and successful career in computational science/engineering. Everyone I have worked with in the last 25 year, with only 2 exceptions I can think of, was smarter than most people. I have heard some truly awful things come out of coworkers mouths. Particularly in the run up to the invasion of Iraq. People who could write software that accurately predicted airflow through jet engines who did not care that the people of Iraq were not the same people who attacked the WTC. They knew, but did not care! They simply wanted to lash out at brown people in the middle east.

No, empathy is the distinguishing characteristic.
