some other bobby-watermelon flying about its business.

Yesterday, a video appeared on the network, filmed by a frightened passenger through the porthole of either a bobby, or a watermelon, which depicts some other bobby-watermelon flying about its business.
I understand perfectly well that seeing an airplane in the sky is an incredible event, especially in the 21st century, so I understand why some upright walkers began to have tantrums in the comments (although spring explains a lot), but it’s not clear why they moved into the “we are being killed” category.
Dear passengers, do not worry, this is indeed a common thing in the sky. Since progress does not stand still, technology is constantly developing and improving, aircraft in the air are under better control and management, both by pilots and ground services, and there are more and more of them, so for the last 8 years vertical separation (difference in altitudes between aircraft) has been reduced from 500m to 300m in accordance with the international rules for flying on a collision course. This was called the term "micro-separation" and is joyfully and cheerfully used by all and sundry.
On the video you can see how the pilot sees this very "micro-separation".
So don't worry, don't worry, fly by plane... (Your advertisement could be here 😀).
You need to worry if a clearly military aircraft appears next to your board and it flies next to you, and at the same time you are definitely not the president of any serious country.
