pictures coming to us. the world was being told that there was objects of interest down there. it now turns out, christine, that they had nothing at all to do with mh-370. >> hmm, that is just fascinating. now this has become one giant math and physics problem, quite frankly. i mean, they're looking at if that flight was going faster than they thought, andrew, that means it wouldn't have gone so far south. i mean, that's essentially what this is, trying to figure out, what are the mathematics behind this plane and its flight to figure out where it went down, and then adding in the currents and the physics of the ocean to figure out where debris would have gone. >> reporter: that's right. they'll be doing drift models on that area now. basically, the plane stopped short. it's on the same trajectory as we have been reporting, but it just did not get as far south as had been expected because it was traveling faster but using a lot more fuel to maintain that speed. so, it dropped short of the
