Let me repeat something. Where the plane crashed and where the current search zone is are two interrelated, but different things. The search zone is where 20 days of ocean currents and winds are believed to have moved things after the crash occurred. The fact that the search zone has now been moved to a location that is northeast of the previous zone does not mean that the crash site has also been presumed to have moved by an equivalent displacement. Ocean winds and currents different in direction and intensity at different locations. Furthermore, the previous search zone was based on two weeks of drift, while presumably the current zone is based on three weeks of drift.
