because its not hard to see how a device used to read your brain signals could be modified to INSERT them too

Yes. Yes, it really is. This isn't the computer reading your mind, so much as it is your mind learning how to talk to the computer. There is a steep learning curve as your mind rewires itself to be able to produce the kinds of signals the EEG is set up to trigger off of. There is no way this could operate in reverse with our current level of technology and understanding.

You're thinking about this the wrong way. Most of these systems are like training your brain how to walk again after a serious trauma. You just hook up electrodes to a patch of cortex and come up with some unique brain pattern that you will use as a trigger for a certain task. You program the computer to respond to that pattern, providing a feedback response. Using the feedback, you train your brain to more accurately produce that pattern, while you simultaneously tune the computer to pick up on the evolving pattern. These are not the kinds of things you just plug in and go, they take considerable time and effort to make work for each individual.

No one cares about sovereign territory. It all comes down to taxes. The government does nothing if not collect taxes. During Apollo 13, Jack Swigert was allowed a 60-day extension on filing his income taxes as the IRS had determined he was out of the country when they were due.

Goodness me, we'd better tell the aviation industry that it's incorrect to call a propellor a propellor when the throttle has been shut or the engine completely killed/died!

If you're actually connecting that propeller to a generator, then yes, it would be a turbine, however I'm not aware of anything that actually does that. There are often pop-out ram air turbines for that specific purpose, either to power weapons and other equipment on hardpoints, or as emergency backup power should your APU or batteries fail. In the case of a propeller, you would call them a retarder, and you typically feather your props to prevent that from happening.

Every prop can function as a turbine and every turbine as a prop.

Perhaps, but not efficiently. You can extract a whole lot more energy out of the flow with a turbine than you can put into the flow with a propeller. As such, a propeller is going to have mild camber allowing modest operation inverted as a turbine, but a turbine is going to be aggressively cambered and would immediately stall were you to attempt to use it as a propeller.

Major damage? Sure, but not fatal damage. The only way for an 80lb craft to cause likely fatal damage is to hit the cockpit and cause fatal damage to its pilots. Wings are tough. You have two engines. You have redundant control systems. The plane would be a total loss, but chances are good there would be enough left intact after the collision to land.

The brain is a wonderful organ; it starts working the moment you get up in the morning, and does not stop until you get to work.
