Dark satire.  Loved the stewardesses — nice touch.

The assumption is that these planes are being flown by humans.  With all the technology now — drones and the ability to remotely control planes — it’s very possible that the planes spraying chemtrails/geoengineering don’t have a human flying them.  This makes it easier to poison people…no pesky human emotions like morality, compassion, guilt, to stop them from spraying us.
