What I remember from the Connexion presentations is that they used
only four ground stations to cover more or less the entire Northern
hemisphere. I think the places were something like Lenk
(Switzerland), Moscow, Tokyo, and somewhere in the Central U.S..
So a Europe->China flight should involve just one or two handoffs
(Switzerland->Moscow(->Tokyo?)). Each ground station has a different
ISP, and the airplane's /24 is re-announced from a different origin AS
after the handoff.
It's possible that there are additional satellite/transponder changes,
but those wouldn't be visible in BGP.
