find this debris area of something, using satellites. now, david, i keep talking about this being the extremes of the range of this jet because one of the working theories is that the jet was flying basically a ghost ship, that those on board, potentially no longer had the ability to fly this jet, that it was flying on auto pilot and it would do so until it ran out of fuel. so it makes sense, that if that was the case, it makes sense it would have -- >> also the satellite data coming out, the plane may have gone along the southern or northern arc. it also suggested it flew for several hours, right at the extremity perhaps when the fuel ran out. so it does add up at this moment, but you have to be extremely cautious at this time because it's only a few indistinct pictures from a commercial satellite.
