perhaps even the track similar to like you see in plane investigations where they piece together the plane in order to get more answers? would that happen here? i think what they will probably use is computer modeling both in aircraft investigations trains bridge you know failure, multiple fatality traffic accidents, they use computer modelling to reconstruct and i think probably do that here. the up fortunate thing is the only the persons in the cab of that train will know what hit it not exactly what but when something hit that train, if they knew that something hit it and what happened because clearly, someone someone or some thing, rather distracted the engineer and the only person right now that can tell that because the ntsb has already told us it s not on the black box case. they don t have that information from the black boxes. but you know i have worked many many accidents where over time sometimes, the memory, particularly these traumatic events the memory does come bac
unknowns, internal bulk heads and tanks may have imploded on the way down. you don t know if you can rely on the buoyancy of the tanks when you go to put air in them, for instance. good salvage companies typically have a plan a, b, and c, so that when they run into the unknown or more information becomes available through the project they can then alter and be flexible to adjust with the realities. and dave davidson, we just had the piece from gary tuchman, and it is not just as simple as hooking up a crane, is it? oh, no, you have to have a lot of different salvage techniques, there is possibly computer modelling. you have to make a plan so you know exactly how you will do the salvage before you do it. and then it is not hooking a crane up. you may remove weight, that is one way you can use salvage

scenario. jenna: that was janice dean, the first meteorologist to predict the monster storm that hurricane sandy would turn out to be and she made the call right here on happening now. just five days before the storm made landfall exactly one year ago today. that s how much notice we had. bringing with it, she had torrential flooding and hurricane force winds. you ve seen the damage, you ve seen the footage. what was it about sandy that made it so dangerous? why has this year s hurricane season been so tame? we don t want to jinx anything. here now is meteorologist janice dean. can you believe it was a year ago today that we were talking about super storm sandy? and i wish that i could take the credit for it but the computer modelling was just incredible. we knew about a week out that this storm had the potential to be a disaster across millions of people, a heavily populated area and the angle of the storm was really the key to why this was such a damaging system.
