In 1857 the poet wrote Justinus Kerner about his fear of what would happen to the airspace in the future. He saw the heavenly tranquility be sabotaged by the spirit of mechanical mobility, by technology and the alarming advances. In the poem "Under the Sky" he writes about what he thought was rain dripping from above, but which turned out to be a leak from a flying oil barrel. Elsewhere in the poem he writes: "I look to the sky, to be sure / About why it is so dark / I discover a draft of goods, which sails past the sun."
Kerner may have been right about something, even though the market has hardly been able – or will be able to – cause a solar eclipse right yet. Yet he had no idea what the airspace would actually be used for in the future: that it could now be filled with flying eyes, so small that one could barely see them, and that they could even shoot and kill. Remote controlled, or off own will.
