The hum of the Earth. Lithuania

Glinskas Cheslovas writes to the Commission on AI:

...

The other time was 2-3 months in advance. It all happened in the evening.

My father and I were building something near the house. Mom called for dinner. And we went into the house. I had just sat down at the table when I heard that whistle again. At first I thought it was a tractor coming (they often drive here). But if the engine speed drops (the tractor driver removes them, for example, in front of the pit), so they should rise. But I realized that it wasn't a tractor, and jumped up and ran out into the yard.

The evening was like all summer evenings - warm and quiet. The sun was still shining. but I didn't have time to run out into the yard again, when the whistle suddenly disappeared again. I looked at this side, where I think the whistling should go, and saw some smoke. It was from the north side, high in the sky. The sky was cloudless and clear. In 2-3 minutes, the smoke drifted across the sky and disappeared.

After all, even a helicopter would not turn around almost on the spot.

Then my mother also told me that one morning she was going to milk a cow and suddenly she heard a whistle, and then some kind of light that suddenly disappeared. This was confirmed by the neighbors who also saw it.
