Maybe I was not paying attention in class, but it seems Jormungand is an autonomous AI system that destroys all aircraft indiscriminately once it has been activated. It indiscriminately robs everybody of air travel, even Koko. It would make sense if it could leave civilian planes alone or obey their operators.
With what weapons does Jormungand enforce "no air travel, ever"? Does it attack even low-altitude gliders? Is is completely indiscriminate, since it destroyed all aircraft at once? Can Koko override it?
