I like the idea of TV screens for windows...just put a pinhole camera on the outside to feed the TV screen on the inside.
It'd use a system similar to the proposed "cloaking" technology they are testing, where tiny screens project what cameras on the opposite side of the object are seeing.
My question though concerning the route from Brussels to Australia is, the flight path over the North Pole. Specifically, taking into account the rotation of the Earth. Even still with a 5 hour flight time, the Earth is rotating toward you in a sense. Which would actually cut the arc more narrowly, but then again on the return trip the arc would be quite a bit broader.
And because this would be a supersonic flight, they'd wanna traverse the Bering Strait instead of coming over Alaska or the Kamkatka area of far east Russia.
