"I myself feel that our country, for whose Constitution I fought in a just war, might as well have been invaded by Martians and body snatchers."

| A swarm of quasi-independent aerostatic devices. |
The reason for including this entry, as well as one for aerostat, is that these machines are capable of communicating with each other. This communication allows them to coordinate their movements.
| Atlantis/Shanghai occupied the loftiest ninety percent of New Chusan's land area - an inner plateau about a mile above sea level, where the air was cooler and cleaner. Parts of it were marked off with a lovely wrought-iron fence, but the real border was defended by something called the dog pod grid - a swarm of quasi-independent aerostats... These pods were programmed to hang in space in a hexagonal grid pattern about ten centimeters apart near the ground (close enough to stop a dog but not a cat, hence "dog pods") and spaced wider as they got higher. |

Together, they form a protective swarm.
In nature, bees swarm for a purpose; an ageing queen, overcrowding, poor ventilation in the hive. In flight, bee swarms approximate the kind of distance between individuals shown in a dog pod grid, with several thousand individuals spread through a volume the size of a minivan, flying together. However, when a bee swarm settles, the individuals congregate in a dense volume roughly the size of a football.
"Guard" bees don't fly around the hive to protect it; they stand guard in an aggressive stance at the entrance to the hive, checking individuals upon entry.
