so far it lost fuel, maybe there's a pocket and it could float, now there's a possibility andette could fill up with water and sink. it goes both ways. david, looking at this, why would we believe the plane would fly as far down west. why isn't it more reasonable to be searching areas in the strait of malacca where it was last seen. >> you've got military radar in the area. they didn't pick up tracks. really it's a process of elimination. if we know the airline wasn't in a certain spot, we can go look into a different area. i think that's why australians and malaysians have gone out this far. no one picked anything up across that part of the world with their military radars. they would have forensic tapes, i'm sure, like we do, that they can go back and double-check
