Actually there'll be a few fun facts

Did you know that airport runways are numbered based on the angle from north? Specifically from the pilots entry perspective. The runways angle is taken, rounded to the nearest multiple of 10, and then the zero is dropped. This also works in 2 directions per runway. So a runway that’s labeled 9 on one side would be labeled 27 on the opposite side, because the first angle is 90 degrees and the opposite angle is 270 degrees.

Fun fact two is about how they define north. There’s many ways to pick a north, though the two most common ones are math (called true north), and magnetic north. Magnetic north is the most commonly used one, but it actually fluctuates. The further north you are, the bigger the fluctuations. Because of these fluctuations and them needing to repaint runways due to the angle changing, Canada became the first country to use true north for deciding how to number commercial airplane runways. Some other countries use true north in some capacity for military planes or certain commercial flights or whatever, but the only country to have it as their standard for commercial flights is Canada.

There’s many ways to pick a north

My favorite method is following the fluffiest animal ie bears or wolves. I feel like they head North sometimes
