There’s also the Great Circle flight paths. Essentially, because the earth is round, it’s actually a shorter distance to fly in an “arc” (when looking at a flat map). In the below picture, the upper curved line is actually shorter than the lower straight line:

Here’s another image which demonstrates why the curved line looks longer on a flat map:

And because of how map projections work, this applies to virtually any flight path that isn’t directly north/south… Just like the one in OP’s photo.

I mean, open source projects can be started or based in the US. But that doesn’t mean it’s an American project; it’s just that the people who started it happened to be American.

I guess if we had to point to a specific American OSS, maybe Tor would qualify? It was initially developed by the CIA, so that may qualify it as US OSS. But it has since taken on a life of its own and the CIA doesn’t have any hand in active development anymore… So it’s still hard to say that even “being made by the literal US government” qualifies an OSS project as “American”.

It’s sort of a Ship of Theseus situation. At what point in the development process do we consider it a non-American project?
