Having constructed my first heavier-than-air aircraft in miniature of balsa wood and copper foil with four symmetrical electrical thrust units, I released the craft outside of my workshop – and up it went! …and up…and up…and well, you get the idea. Having not tethered the device and having run it upon the formation of electrical energy from Aether converters, there is no real limit to how far up it will go!
So here we are with the situation that somewhere over New Babbage airspace is a vehicle climbing at the rate of about a meter per minute up, up, and away! It being a small craft, one will never find it and it is stable and all that, and running on a never ending energy source… well, I shall have to consult the astronomers to find out just where it may end up.
