I don't understand that term. It became popular around 1997/1998 so I'm guessing that pre-1997 Somalis used it as a term to separate themselves from post-1997 Somalis. Which means that Flight 13 was a system that began running during that period and onward. Who knows, maybe we're on like Flight 18 or 19 now, but I guess the term stuck.
But that's just a working theory. Its not fully developed so I'm wondering if any of you smelly qaxootis can help me figure this out.

Smelly Somalians!
