the debris will tell them how the aircraft came apart. so for example, a bomb blast, which isn t in this case. it would have residue. it would show strains, certain parts of the metal may have twisted in tern areas. the impact, the dense, all that would be shown on the actual metal. we saw these images and we also keenly looked at them, these were the first signs of debris and we know there was an area that there was a lot of debris. it s a big shifting area. but you saw something that made you say, wait wait wait, there could be a survivor. which i think we re so reluctant to even go there, david. what made you think that? i am as well. it was kind of an initial reaction andern soly what made me think about that was the fact that there was a door and right below the door is mounted the slide, an exit slide so whether or not it deployed or came apart during the breakup, that s still in question. they don t deploy unless they re deployed on their own?
