Synthetic planes’ alphabet.
I was thinking about my aeromorphs once again and as a result decided, that they need their own unified language. They understand human languages (mostly English + one or more of the country, where they were born), but between each other they prefer to speak Airborne (I’m still coming up with the name), which alphabet shown above, because it is greatly simplifies communication by reducing diversity of accents (and thus - misunderstanding) from different parts of the world.
I figured it out last night, trying to make all symbols easier to write, maybe will go further in grammar and syntax
