> You know of a path that keeps the acceleration 1G and pointing downwards at all times?

Yes, but you're not going to like the outcome.

Freefall.

[shalmanese]

Freefall is a 0G maneuver.

[jacquesm]

From your perspective, yes. But you're accelerating with 1G right up until you reach terminal velocity (or impact) unless you're in orbit.

[shalmanese]

Maneuvers are always from the reference frame of the passenger. If a passenger is feeling subjectively to be in 0G, it doesn't matter what their acceleration is compared to any fixed reference frame.

Or if you are just far enough away, with just enough lateral velocity, you keep missing the planet. Silly astronauts, can't even fall properly.
