we're looking for the haystack or whether we're looking for the needle. there is effectively two independent searches going on. we're talk whack rosa was talking about what happens beyond the assumption of where the impact point was and how the currents might affect that. what i would like to go back and interrogatory the assumptions where the impact point was. what i mean by that, how far it's traveled there are three to five assumptions that we're using. we're using speed, altitude, we're using endurance, how much fuel did it have. what was the track after the last transponder ping to when it actually turned south. and all those assumption also inform where the impact point was, which we don't know, and then we're trying to base further analysis and science off where the impact was on the currents and the drift. so it's impossible. >> you said that listen, the ships that are out there now, the planes, they want to get to the debris if possible or objects. that ship wants to get to the plane, to the pinger, right? to the data reporters?
