way to drown, that's it. because you get a little bit of air, you get shoved to the bottom of the river, then you come up. and that's the most frightening part is, we know she's getting tired. we've seen her swimming. she's tried to swim away from this raft a number of times and she just gets sucked right back to it. >> let go of the boat! >> john lane screams to her to let go of the boat. they need her to go downstream if there's going to be any chance of saving her. finally naomi lets go of the boat. then she disappears into the white froth. >> and i just wait and i watched. and nothing came up. and then about 40 feet past me, all of a sudden she pops back up in the water. and at that point she's moving so fast, she's gone so far past me that i can't even throw my rope.
