The only acceleration I was concerned with my answer was the acceleration inside the spacecraft itself, which is its proper acceleration. It's nice to be reminded of the niceties of relativity. | |

A ship with constant proper acceleration will have decreasing coordinate acceleration in some frame as it approaches the speed of light in that frame. | |
