question becomes why chairman mccaul. and there has been speculation that this plane may have land somewhere with the hopes that it could be used at some point later as a weapon. programs loaded with explosives. how seriously are security officials taking that scenario? >> well, we're concerned with that. i know there are two routes that it could have possibly taken. one would be to the north toward kazakhstan which would be close to afghanistan, pakistan. i think that would be unlikely because our radar detection systems would have picked that up had it gone that route. i think the intelligence community and homeland security believe that it possibly more likely went the southern route toward australia, indonesia. now two scenarios are here. one is that the plane ran out of fuel and land in the ocean.
