welcome back. breaking news, the bluefin 21 has nearly completed its 12th mission, 90% of the search zone scanned. and yet another deadend when sheet metal with rivets washed ashore has been ruled out as debris from this plane. it raises the question, is it time to rethink the search vat gee? jean casaras has more now. australia will not rest until we have done everything we humanly can to get to the bottom of this mystery. reporter: it is a mystery no closer to being solved. the bluefin 21 autonomous underwater vehicle has searched the targeted area with no luck. experts are preparing for the next phase of the recovery effort. this requires deep sea ascents. this requires more probably bluefin 21s. this requires probably
very, very unlikely that they will find any sign of mh-370 from that visual search. so, the focus really now on the bluefin-21. as of this morning, we understand the joint agency coordination center, that it was on its 12th mission, having scoured about 90% of that narrowed search area, so far finding no signs of the missing plane, but authorities still looking. no timetable as of yet as to when it will finish that up, no concrete timetable. in fact, we re hearing conflicting things, some australian officials saying it could be wrapped up in a matter of days. the australian defense minister yesterday saying it could be a matter of weeks. john? what about that conflicting time frame right there, erin? because you ve been reporting this, you know, for days now. there are those who are saying it could be today, tomorrow when it s done, it s 90% complete with the search, then just yesterday telling us that it could be two more weeks. what s the basis of this conflict?
