The question arose whether H.S. meant constant acceleration as measured in the Earth frame, or constant proper acceleration (i.e. the ship's accelerometers measure a constant 1g). Only H.S. knows for sure, but since the former is impossible, and the latter is a very reasonable and comfortable flight plan, I took him to mean the latter.
