On the morning of the 19th, I woke up from an incomprehensible monotonous hum coming from behind the forest. My family and I then lived in Zhavoronki near Moscow - we rented a dacha there. Having woken up, I was no longer able to return to my morning sleep, but for some reason began to listen to this strange hum. In this unclear, but, as it soon became clear, historically important noise of the time itself. I went out onto the porch.
