Default Myth: 1 G barrel rolls are impossible.


Well, MX, consider the case of a ballistic track that starts off with
an initial vertical velocity that is less than escape velocity.

Up, then down, until it hits what someone so nicely described as 'the
hard edge of the sky". Is your assertion that is orbital?
