The general consensus about FFVIII is that the military technology is at least modern. I mean, they've got machine guns, rifles, armored vehicles, attack boats, long-range missiles, even some badass robots.
So why aren't there any jets? :o
With the exclusion of Ragnarok, there isn't a single vehicle remotely similar to a fighter jet, bomber, etc. You'd think with all their fancy-pants equipment, they would have thought about that pretty important aspect of warfare.
Now, I know this is a game, and games don't have to make sense, but I'm a speculative kind of guy. Any ideas as to why there aren't any planes in FFVIII?
