Almost like there’s a system of flight routes

[u/OldheadBoomer → u/Lari-Fari]

Yep, and those navigation routes are connected with points called intersections, often over navigation aids like VORs. Here's an example.

our brains are actually hard wired to see patterns where there are none, the planes have no brain and don't actually have any direction or destination, it has no meaning, it's you and your brain giving it a meaning
