Precisely, but further still; one must consider the relative perspective of the subservient witness on the parabolic progress. If the perpendicular tangent to focus places the intersecting reference point anywhere below the intersecting midpoint of the latus rectum, then we're golden. If it lies anywhere above our latus rectums well, I don't need to tell you what that means. Of course, this is mostly academic.
I assume you are discussing the cow jumping over the moon scenario. I doubt this is possible, but I hear there is cheese. I think we need to take this to SpaceX to run some hard numbers.
