are air pockets. this was a car carrier, a ro-ro, roll on, roll off, as well as a passenger vessel. it took on water very quickly probably because of that. so there is a less likelihood, i would think, with a ro-ro type vessel, a car ferry-type vessel, that there are substantial air pockets. but this is a large vessel and undoubtedly there are air pockets here and there. that's what they're hoping for. that's what they're going to look for when they get on board. >> i so hope you're right. i wanted to ask you, too, about safety procedures because apparently nobody knew what to do. they told these poor students to stay on board the ship. some of them went back into their cabins. that's not what you're supposed to do, right?
