[Story] In spite of the dusk, the engineers hasten to put into operation the new engine. Their leisure time was interrupted by a sudden raid of triangle-shaped UFOs. In an effort to preserve their relative peace, they quickly filled the bill with tools to the point where there was no gap left. Probably, it was an alien message, but they couldn’t explain the meaning behind it.
