You’re still picking out logos that fit your theory and ignoring the ones that don’t.
Again, as an example the ESA logo is an “e” and a dot inside a fingerprint like patterned circle;
zeus.nascom.nasa.gov...
Look at the others I mentioned, and many more, and a large portion have no resemblance to that symbol.
Here’s a list of space agencies;
en.wikipedia.org...
The reason for it’s prevalence in the rest has already been adequately explained; i.e. it’s culturally associated with movement and is the
simplest representation of an aircraft (I even use it in my avatar) possible. I’d also add that as NASA uses it many will try to emulate that.
