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.

As has been said before, and is also readable in that blog entry: the
system is supposed to create *one* advertisement change when the plane
is crossing from the "Europe" to the "US" ground station (etc.), not
1000+.

The comment still applies. Imagine that this system were implemented globally
on all international/intercontinental air routes. It would still be nice to
avoid having each of those airplanes cause a globally-visible routing update
whenever it crosses some geographical boundary.
