refining the assumptions. but still you're just basing your end point only comes from your beginning assumptions. we've look at the bottom of the ocean. it's not there. therefore, the assumptions were incorrect. if the plane is not found in the next few days, it simply is not there. >> and you're saying -- richard, okay, go ahead, richard. you're fuming in kuala lumpur. >> no, jeff is -- i am, i am. it's early morning here. it's already humid and i'm getting hotter under the collar with jeff. we haven't searched the bottom of the ocean yet. they are searching the most promising area, which we'll have to widen. and there may be inaccuracies that has to be searched. but stop looking for certainty when all you're dealing with is the best information that you've got. and to suggest, jeff, that somehow this data is incomplete or inaccurate or not wrong simply ignores the number of people who have looked at it.
