Biosphere II, north of Tuson Arizona. considered by the press to be kind of a giant sad failure, considered by myself to be a radical experiment in ecological engineering. The result of the test run was not what they expected, but science is not about what you were expecting. Arcosanti, outside Mayer, Arizona. Experiment by Paolo Soleri in urban engineering, arcologies.

My understanding is that the plane broke up in flight and came down in a number of places. Besides, blowing it up makes it smaller, but does not hide the various materials, layers, and coatings involved.

A warship is basically a large steel box filled with things that are radioactive, flammable, explosive, or covered with sharp metal edges. They can deal out a hell of a pounding, but can't take that much of a shot, kind of like a heavyweight boxer with a glass jaw. Ammunition storage and handling is is inherently dangerous. If you can remove the gunpowder from your projectiles you now have a much less explosive ship.

As regards civilian uses, this is a potential way to put bulk materials in orbit in a hurry. Nothing living or delicate could take that 100 Gs, (or whatever) but you could send up a lot of air/food/water/clothes/tools/ etc, and they would arrive in orbit in perfectly good shape.

The system operators will be fully uniformed, as per the Geneva Conventions. The weapon system will be fully camouflaged, as per universal custom.

The first time an officer fires this at a suspect vehicle, and hits the Cadillac dealership right in back of the suspect???

If a civilization is advanced enough to travel here, they're probably advanced enough to not have any good reason to be hostile.

If I decide to build a vacation house in the Everglades it might get a little rough for any alligators that happen to live on "my" lot. I'm not going to care if they've been there since sometime in the Mesozoic. I'm aware that alligators have some kind of intelligence, however I'm not that interested in it. They will never understand where I came from or how I got there, or what the hell I'm doing inside that big glass box my contractor put up on their best feeding ground. Any that get in my way will be dealt with, it doesn't matter how well they plan their defense. About all they can do is hope that I'm not a predator...

An ideal car system would have four fixed cameras and a mike. You would have a fixed forwards pointing camera that could see the dash and something of the road. Speedometer and turn signals would be visible, along with enough view of the road to judge your driving. Traffic lights and road control signs would be nice. You would have wide angle left and right facing cameras mounted in the "B" pillars, just a little glass dot on the outside of the pillar. The rear facing one I am undecided about. Cops like to shine as much light as possible at the back of your car, this would tend to blow out most images. You might be able to get around this by mounting the camera very high or low and aiming it at a sharp angle. The mike gets clipped into your collar if you see an encounter coming. It is designed to record you but not the officer. This may keep you out of wiretap charges, since you are only recording yourself. You can of course echo much of what he says to get it in the record, so long as you don't annoy him. Recording an officer without permission can be made into a crime. Recording yourself, not so much. Around the tops of the windows you have "you are subject to surveillance" warnings.
The system is designed to come on with the car. If you hit the unmarked button on the dash it starts saving what it sees. It is always running a five minute buffer, saves the buffer when you hit the button.

This gives you the ability to record any encounter near your car beginning five minutes before you get pulled over. He won't like you recording yourself and will probably confiscate the mike, but there's no help for that. If you have mad skillz you can also try to pipe the results off site. If a LEO realizes that he's recorded in the vehicle somewhere he can always confiscate it and have the car stripped right down to the frame looking for the data.
