did this surprise you? well, that kind of thing happens. you try to be aware of that if you ve got an accurate base map to begin with. which is our first problem, we don t have an accurate base map, right? if they ve got one, we haven t seen it. when the floor takes the dive, so does the vehicle and the vehicle goes, oh, no, i m not supposed to be here and punch it out. what did you learn from yesterday s search, the aborted search. it was only down there the whole trip was 7 1/2 hours. how do you adjust today? their tactics are going to be important, having looked at where else in that area they can look. i guess they re moving to an area that they re more confident. let s take a look at some of the topography that the bluefin-21 could be coming up against. i want to get your take on really what this means for the search. first, is the issue of landslides. this was actually surprising po to me. i didn t noland slides could occur in the mountain floor.
