no one has really even gun to look in that southern most track yet. >> how long will you be out there searching? >> great question. when we started out in the gulf of thailand, it was a very defined boundaries. it had a defined parameter. normally, in the u.s. navy, what we do, the first 72 hours, that's critical to finding people and survivors. the first thing we do is launch a helicopter. that's what we do immediately. you have an essential point, a starting point to look. your helicopter starts there and slowly works its way out. now, we have a whole ocean. quite frankly, it's a pretty unprecedented scenario. i can't tell you how long we will be out here. we have 300-400 sailors right now. we had 700 at one point. they are doing a great job. this is a 24-hour business for them out here.
