With an invention like the helistat you can at least understand the appeal. Who has not stood in a remote location looking at your destination over trees and past mountains and thought "god dang it what if we could just fly it over there?"

This is "An Invention" maybe not a good one. But it makes (some) sense.

There are other new technologies that are just as unstable and nerve-wracking too look at but they somehow also lack this basic quality: a reason to exist.
