We don't know if Eric97217 meant absolutely pulling up to vertical or just pulling up. The maneuver described sounds like a simple split S to me (also called a Reverse Cuban Eight). The fact that he alludes to A-10s using this maneuver to quickly reverse direction makes me think he's describing a Split S, also. Since it's difficult to describe the movement of an object through space, unless he better describes what he's seeing/doing, we'll never know.
