No Kaptin, there is no parallel between the Erebus crash and the current debate about inaccurate Swiss charts. Any professoinal pilot knows that amendments, revisions and Notams are an almost daily chore. He therefore applies airmanship to update and cross-check his navigation using every available means. The flight plan track provided to the Air New Zealand Antarctic flight might have been offset to that which the crew expected, but the fact remains that they did not check it and that Captain Collins descended below minimum safe altitude without having positively ascertained his position.
