because apparently they recalculated how fast the plane was flying across the malaysian peninsula after it made that left turn moving away from beijing, heading in the opposite direction. how did they miscalculate where the end point was? what did they do to refine it now by 700 miles? >> well, if you remember early on, we had the aircraft turning in multiple directions. we were concerned if the waypoints put it on the ground, in the air, we didn't really know. and there was so many potential variations in altitude, which certainly would change the entire fuel calculations, which would be the range of the aircraft. so i think what they were doing now, based upon the pingers, and different altitudes and different speeds, they have refined it now to a point where they really believe that this is going to focus in on the search area. >> this reassessment, you buy it? you gave us an indication yesterday that they were -- they had discovered this new area where they want to devote their search efforts. >> i think they had really put
