Re: 2072: "Evaluating Tech Things"

Well this isn't a view from the interior of a tornado, but it does show a view of the interior. Very cool. Probably looks much the same if you're actually inside the thing. Unless the lenses of your eyes are too distended from low pressure.

Re: 2072: "Evaluating Tech Things"

I thought that, near the bottom of a tornado, things get drawn IN rather than blown away. Granted there might be some stability issues in the strong wind speed gradient, but I think a suitably massive drone with a good head of speed could punch through. I wonder what it would look like inside?
