which is a perfect flotation device. a sealed cell flotation device that could float for years. >> this is a question from philip. can a plane enter the water in such a manner that it leaves no debris. a lot of people have been asking that. do we know that now? >> i used to be an aviation history professor and we would find in researching planes from world war ii and older planes, occasionally they would remain on the ocean floor and lakes and bodies of water completely intact. but in modern times, not really. there are not many accidents where that happen. there are a few private smaller planes that land on the water and sink. there are small private planes where that has happened. it is possible. and the 777 is a tough plane. boeing built it to last, apparently. it's possible. unlikely, because if you are coming in to make a sully-style landing on the water with these high seas if you caught a wing you would cart wheel and it wouldn't be a smooth landing at all. >> what would the experts have liked to see done differen

tell them to wear a flotation ring and abandon ship. >> will they be rescued right away?> don't let them evacuate without safety gear, tell them to be safe. >> it is not known why the ship capsized, but it did make a sharp turn before it began listing. during 470 six people, most of them high school students, only 170 survived. much to the despair of family members. strong currents have made it difficult for divers to recover the bodies, and coast -- the coast guard said on monday they began to use underwater drones to search for the missing. >> syria's presidential election will be held june 3, the announcement was made by the parliamentary speaker of the country earlier, and candidates can begin registering and for the first time more than one candidate can stand. while the election war is raging may be a tough challenge. we report. >> despite the ongoing turmoil, the years of fighting with 150,000 people killed, bashar assad has never considered setting -- stepping down. he will run for a third time and there is lachance he will lose in what many call a sham election.

of the royal mill share price remains about 70% above the flotation price.oes the prime minister rule out paying a four million pound money tom taxpayers government advisors? >> what i would say to the honorable lady is the taxpayer is two billion pound better off because we were able to put this business in the private sector where as previous governments failed so dismally. >> mr. speaker, ply constituent is seeking the right to be treated by the english grand. will the prime minister investigate what could be done to help her and other n.h.s. refugees who is seeking the highest standard and lower waiting times which are being delivered by this government? >> my honorable friend is right to raids this. -- write to raise this. frankly, what is happening in our n.h.s. in wales is a scandal, and it is a scandal that is entirely the responsibility of the labor part running the government. they made the decision to cut n.h.s. spending by 8% in wales. as a result they haven't met a a&e target since 2009. the last time -- i don't know why the leader of the opposi

shall we go onto flotation? what's wrong with my reasoning like most people in the world? what's wrong with my reasoning? i'm not considering the whole story. and the whole story is not only weight, but volume, ahh. so what would have to happen to the volume if this density is going to get more? how many say the volume would have to get bigger too? everything gets bigger. you may want to make some bigger-- everything, come on, come on, the volume gonna get smaller. and when you push it under, can you think of any reason why the volume should scrunch up smaller? water pressure. can you? depth, water pressure. but the pressure of the water is only going to to be a little bit more. oh that's more, that's more than what it is now. that's right and that's going to make the volume a little bit more, a little bit less. and if the volume is a little bit less the density is going to be a little bit more and if the density is a little bit more, it's going to --sink. so it sinks, yeah, yeah, yeah. did i get that one right, gang, huh? okay. isn't that true too of you when you're swimm

it's maintaining its flotation level. this is why he believes it is possible there could be air pockets inside. of course, it is incredibly difficult for divers to even get close to the ship, let alone get inside those cabins they haven't reached yet. the visibility is very poor. we're hearing it's something between 30 and 40 centimeters. some divers can't even see their hands in front of them, it's such bad visibility. they are continuing to try to get inside the cabins. they're trying to get inside the cafeteria at this point. because it did happen earlier in the morning, about 9:00 in the morning is when the distress signal cawas starting. most people they believe would have been in breakfast and may be trapped inside the cafeteria. >> four crew members are facing charges in this tragedy. tell us about that. >> that's right, yes, four more crew members. this just adds to the crew members that have already been charged. the captain has been charged on five counts. if found guilty, he has a maximum of a life sentence tha

to 50 feet below the surface of the water but it's been there for sometime and maintaining that flotation level. so of course, this is still a search and rescue operation and i think many families will understand that that hope at this point has to be fading. the fact that they haven't pulled anyone out alive since wednesday. >> every moment that passes i'm sure that must be agonizing. also, i'm curious, how are they letting the parents know if their child has been found? how are they identifying the bodies and communicating that to them? >> reporter: well, it is a heartbreaking scene in the harbor behind me. what they were doing a couple of hours ago when there was a cluster of victims, of bodies found and they knew were coming back the shore, there was an official on a loudspeaker effectively describing who had been found, describing the gender, the height, the weight, the clothes that that particular passenger was wearing. and there were many passengers around listening, wondering if that's their child and recognize what they were wearing. >> i understand it's perm yatding the area the

impacted the water and remained in such good shape that there is no -- you have 400 seats that are also flotation devices and galley carts should be floating around. >> if it broke up and fell out. >> it is not like a lightweight thing. your talking about truly massive. one step down from a 747. you are talking about it hitting 100, 200 miles an hour at least. these things are not designed to withstand that. >> if it landed like sully landed on the hudson, would it sink intact? >> most likely not. the other thing to bear in mind is if we don't find any wreckage, we start to ask some fundamental questions. one of them, is it on the bottom intact? is there another explanation? really, the only reason we think it is on the southern arc and not the northern arc is because of this analysis done by inmarsat. they said it is more likely that the model of the southern arc was better than the model for the northern arc. there is an entire another set of scenarios. if you don't find debris, when a search area fails, you have to go back to the original. >> get back with the computations and make sure they a

>> can you give us a sense as well, if the aircraft does make a successful landing, what sort of flotation devices does the aircraft have, indeed, to try and make it float? obviously if this was a mechanical failure of some sort they would be deployed, i'm assuming? >> yeah. it has. you have your lifts which actually are tethered to the aircraft. they can be deployed. and you can -- you can stay with the aircraft or you can cut them loose if need be. everybody has a life jacket. you don't deploy the life jacket before you get out of the aircraft, obviously. they tell you that before you depart. aircraft that have a -- a tail canted at a higher degree angle have a tendency to sink, actually. there's a greater likelihood the aircraft isn't going to stay up aloft or stay afloat. this airplane, the 777, the tail is relatively in line with the rest of the fuselage which bodes well for a water landing. so there's a lot of things to consider with the water landing. too much to talk about 50 feet over the water at night. >> now, mitch, i mean, you made it quite clear you're actually doing a powere

hands him what looks to be a flotation device and ultimately, this ends well, he pulls him to safety.his all happened, this was a road, by the way. it's now a river. unbelievable, just one of so many stories we're reading here. pensacola, florida, at least one person has drowned. look how far up you can see how far that water was based upon the windows of the cars. florida's governor declared a state of emergency for 27 counties. he told me this is the worst thing that i have ever seen. do you want me to go to that? pause, let's go to oklahoma. >> questions that we have had in our office in relation to the execution last night. last night the state of oklahoma executed clayton lockett. in 1999 he physically assaulted, kidnapped newman and had an accomplice bury her alive in a shallow grave. he also repeatedly raped a second woman. he was convicted in a fair trial by a jury of his peers. he was then sentenced to death. he appealed the execution and that appeal was rejected by the oklahoma supreme court and the oklahoma court of criminal appeals. he had his day in court. i believe the l

you have to have the metals to keep the electronics safe but you've got to have equal amount of flotationup to the surface. you want to protect that so that doesn't implode and the electronics, the housings don't implode, too. >> as we talk about it imploding, it wouldn't necessarily completely implode and disintegrate but it would damage the bluefin enough that it would be inoperable? >> anything with an air pocket is going to get crushed. not only crushed but once it gets crushed it explodes outwards because of the incredible violence of that. it can take out the vehicle without too much trouble at all. >> with that consideration, what then -- how do they factor that into when they decided to go deeper than they originally thought? from 4500 meters to 5,000 meters. is there a big difference there? >> there's a big difference. they have a way offed a justing the software and looking at the components. i'm sure they built big margins in the safety of that vehicle so they could stretch their operating depth out a little bit. >> they wouldn't be doing it unless they knew -- >> i'm sure the

oh, well, we've gatt that handled now, where is the pressure to do things we are talking about, flotationata. those are better solutions that provide much more information, much more quickly about what went on in the aircraft. i hope it's not viewed as a fix. it's simply a band-aid on a big symptom out there. >> david, is that a fair point of concern going forward? that's one thing we know for sure in a situation that's pure mystery. you have to make a plane completely trackable at all times no matter what? right? >> yeah, the last thing you want to do is have a plane go into the water and not sure where t it is. that's a huge area under sea. you don't want to lose a plane in the water. >> now, when prime minister tony abbott said they may stop searching at the end of the week to re-evaluate. the malaysians saying they need to regroup. to david's point we were making earlier about being fair to the process here, is it important for people at home to know you have to give time to do this the right way, otherwise you're going to see just frustration for the families? >> absolutely. in inves
