They are moving the assets and the cost, i suspect they have an area they want to search. >> did someone deliberately turn off the planes communication systems? >> we dont know. its possible to have a cascading fire melt down of the system that you lose the navigation systems and lose communications and tron respoan. >> we know its shut down. 1:21 a.m. 14 minutes after the plaens data reporting system shut down, the communications were shut down manually. thats why i ask you that we. >> not nece...

Whoser to make sure theyre always safe and reliable. safely. >> reporter: can we actually look in? >> sure, sure. >> it vibrates the atoms at the rate of a million billion per second. that is so fast that heat cannot be conducted, shock warvts cant be conducted. >> reporter: theres a big debate right now where people say is this testing really sufficient to be absolutely sure that that nuclear device will go off? how do you answer thatty. >> well, we probably look at these weapons today more ext...

Be conducted, shock waves cant be conducted. >> reporter: theres a big debate right now where people say is this testing really sufficient to be absolutely sure that that nuclear device will go off? how do you answer that? >> well, we -- we probably look at these weapons today more extensively than we did even when we were doing nuclear testing. there are hundreds of ways that a nuclear weapon could fail. weve found failure modes in the stockpile that we could never have found with nuclear testi...

Certain period of time. if that plane flew on for six or seven hours with no pilot inputs whatsoever im wondering how much they will be able to learn from the recorders? >> and that really brings up another point which is that the airplane did not communicate to the outside world. and maybe one of the failure modes that we just never thought about was maybe we should have the ability for that airplane to be able to communicate via satellite, to the outside world without any pilot interaction. i ...

But they will have the ability to get a great deal of forensic evidence what may have physically what happened to the airplane by looking at how the structureed tore or came apart. to see if there was any fire damage. to see if there was any damage that happened to the aircraft before impact. all traffic investigators are trained to do that with ferrous and non-ferrous met it is as well as electrical wiring as well. the accident reminds me of problems we had and issues with the apollo 1 bad fire...

Inspections, the mechanics look very closely at the skin. where these cracks have developed are in the lap joint. these are subsurface microscopic cracks where you need have a more comprehensive program such as ultrasound or x-ray. that wasnt required in this lap joint. so the inspection was fulfilled, however were now fining out that these failure modes, these stress cracks were in an area that werent preplanned or pre-identified by the manufacturer so the inspection program didnt need to be th...

Work, there was a backup plan, a fail-safe to the fail-safe, a so-called dead mans switch. the dead mans switch also failed. why? because someone didnt change the battery. so to recap, the growing list of problems with the deep water horizon oil rig owned by bp, dead battery, bad wiring, leak in the so-called blowout preventer. but perhaps the most damning evidence to come out was this -- when transocean bought that blowout preventer, which was supposed to prevent the catastrophic spill that wev...
