This vehicle is clearly sub-orbital since it moves at only 1/3rd of orbital
velocity.

Which brings up the issue of overflight rights. Up to what altitude is
recognized as a country's soverign air space?

The altitude their interceptors and SA missiles can operate at with a
high PK.

Seems pointless to make an aircraft that can be based in the US so as
not to rely on unreliable "allies" for basing rights if these same "allies" will
still need to be consulted for overflight.

If the Chicoms build one and fly it over the U.S. we would have a "cow."
So I suspect the whole world is a ****** with this plan.
