Right on, Mark. Here's an alternative  way to look at it. Think of the
rocket's trajectory as that of a bullet fired upward (not necessarily
directly) into the air. The equivalent of brennschluss occurs less than a
second after firing. It's like as if launch crew had neglected to put more
than a thimbleful or so of propellant into the tank (they were off
letting Katje have her way with them). Yet the bullet continues in
its inertial path (objects in motion and all that) upward--until
gravitational force is sufficient to start it downward--all the time
tracing its by now proverbial shape in the sky.
