One might also imagine that more globally-friendly way to implement this
would have been to build a network (VPN would be adequate) between the
ground stations and assign each plane a prefix out of a block whose subnets
are only dynamically advertsed within that network/VPN. Doing that would
prevent the rest of the global Internet from having to track 1000+ routing
changes per prefix per day as satellite handoffs are performed.
