Hear from the leader of the antigovernment movement. Plus being eight and being the child of a migrant farm worker. Well take do you the Strawberry Fields of california. And we begin with a mystery that seems almost impossible with todays technology, a bowing 777 disappears out of the sky. Three full days later there is still no sign of the plane nor the 239 people onboard. Richelle carey joins us with more. Authorities know two men boarded the flight carrying stolen pass ports. Today there are more clues about the passengers. Saturday 1 30 am. Air Traffic Controllers lose contact with the malaysian airline, the bowing 777 jet liner is never heard from again. It is unprecedented missing aircraft, mystery as you can put it. It is mystifying. And we are increasing our efforts to do what we have to do. Dozens of search and rescue crews, ships and plains deploy from ten countries. An oil slick and floating debris are found at sea, all prove to be unrelated. We had to find the aircraft. With no black box signals, no physical evidence of the plane, authorities are looking to learn more about two passengers who boarded with stolen pass ports. Security officials at the airport never bothered to check the facts. Malaysian authorities are working with other agencies, including the fbi. Authorities may have already identified one of the men, but his name has not been released. Officials say their tickets were purchased in thailand with cash. They said it is likely an iranian man bought the tickets for the passengers, but it has not been confirmed. Police are wondering if they are involved in stolen passport ring. And its being reported that the u. S. Is being sent the fingerprints of these two men so they can be compared against a database of known criminal and terrorists. Its baffling to think with todays technology a jumbo jet liner could disappear into thin air. Jake, just about every cell phone has a gps segmental, so why cant authorities find this huge airplane . The difference is that cell signals are incredibly inexpensi inexpensive. A plane as it traverses the vast expanses of ocean needs to be able to use a satellite up link, and that costs an incredible amount of money. Right now the stateoftheart is for these planes to carry disk drives, these black boxes rather than transmitting live the way you and i are used in our cars with our cell phones. So can the technology be updated any time soon . It is a cost question. As the years go on air travel is becoming safer and safer. So the cost calculus just doesnt make sense i think both in the view of the faa and the air lines. A study conducted about ten years ago said that for planes to upgrade to that kind of technology would cost each airplane about 300 million per year. So its really unlikely in an era where air travel is as safe as it is that they will make those investments. The thing to remember is that in the sort of grizzly calculus that we have to do when you look at the cost benefit ratio of things like that kind of investment, is the chances of passengers surviving a crash. And in this case, most crashes take place during takeoff and landing. This was in the middle of the flight. And when you are looking at a fall from 35,000 feet to the ocean. You are not looking at the kind of conditions where the pilot touched down on the hudson and everybody got off okay. When you hit the water the way this plane likely did, it is going to be like hitting concrete. So even a days jump the way you would get out of live transmissions wouldnt make that much of a difference. Jake, thank you. Mark weiss is currently with the spectrum group. He has flown the bowing 777, mark, welcome. Thank you. So how likely do you think this was an accident . An about of terror . No an accident. An accident . Frankly, my opinion, and my gut feeling is that this was not an accident. That airplane is an extremely safe airplane. Its a good airplane to fly. Its a stable platform. Its forgetting. It is built with pilots in mind. Its system is a very straightfarr ward redundant. I dont think that airplane came out of the sky on its own validity. If there was a technical problem, did the plane follow the protocol for communications . Well, theres a very fundamental belief innoff in aviation. One pilot will fly the airplane as safely as possible. The other pilot will assist, and then communicating. An airway where this airplane was flying is very much like a highway, and you are not the only one there. Its a threedimensional arena. And you have to announce your intentions if you are going to deviate from your flight path. So if you had an event that you had enough time to turn around or change your altitude or change your flight path, someone in the cockpit normally would have had enough time to articulate that to air traffic control, and if they were out of range of air traffic control, that is a road, basically in the sky, there probably were other aircraft in the vicinity that could have picked up the transition. But they didnt. So lets just play this out a bit. You suggested it probably wasnt an accident. Do you have some suspected theory . My theory is no more valid than anybody elses. And it is absolutely speculation. Based on all of the evidence, that we have so far, which is almost nothing, but we do no you obviously have drawn conclusions about it not being an accident makes me wonder if you have additional theories. Thats all. My thinking is there was potentially a breach of the cockpit. Somebody forced the pilot to become incapacitated or struggle, to put that airplane into a drive that get it out of the sky in an extremely quick time. What about a loss of oxygen . If you had a decompression on the aircraft or explosive decompression on the aircraft. This is something that is practiced on a regular basis by the pilots. And pilots have in that airplane what they call quickdawning oxygen masks, and smoke goggles already attached to the oxygen mask. And you would be putting that on in about 5 seconds. But yules think about it, you would also have time to have a radar footprint, you would also have enough time to enunciate what was happening over a microphone. Because built into the mask is a microphone. Talk to me about how personal a crash like this is for someone like you. What is this like . Well, you know, i i think in the aviation community, any time something happens no matter what airline it is, who they are, the flight crew and certainly your heart goes out to the family and friends of those people. You know the training that those crew members went through, and, you know, pilots want to come home, flights attendants want to come home. That could have been me on that airplane, and certainly with the kay way cochairs and allian alliances, potential i will passengers could have potentially gotten on another airline at a connecting point and flown to the United States. There are a lot of people in our business, in our profession that are saying look, how is it possible that this big airplane goes down and there is not a trace, and that we havent seen anything on the water. But can you talk about the size of the area that they are looking. Well, you know, i i think theres somewhat of a misconception in the sense that the area that the aircraft went down in, it may be smaller than the atlantic where the air france 447 went down, but remember, that took a number of days to find that, and it took quite a while to be able to finally uncover the wreckage. I think what you will find is while the water may be shallower, that area is still pretty big. So i think its going to take a little bit of time. But you know, until they find the flight data recorder and voice recorder, you wont have any defensive answer as to what happened, and certainly one of the keys would be if you did get any debris, if there were an explosion, it leaves a footprint on the metal, and how it would be displayed to investigators would be an enormous indication of what happened. Do you have confidence theyll find that recorder eventually . Yeah, i do. The recorder, there are a couple of them on the aircraft. And its in the water somewhere, just not in an area where they are checking right now. They have broken the search area up into a grid, basically, and they are checking each square of that grid, and may have to check it again. Because the debris may migrate due to currents, but im pretty sure the battery will last at least a good month, and im sure they are going to find it. They did find it in air france in much deeper water. Very, very tragic story, and a mystery still. Mark thanks for sharing your incite. Thank you. The state Department Says three americans were on board the flight, two children, a four year old and a two year old, the third is philip wood from texas. Wood was working and living in malaysia after spending a few years in ibms beijing office. His family says he visited them in texas just last week. This situation is raising a lot of questions about security and how easy it can be to travel with fake or stolen documents. Its hard to believe in this day and age, people with board planes with stolen airports. The airport never checked to see if the two passports were indeed stolen. Last year it is reported that people boarded planes a billion times without having their passport screened. After 911, interpol built a huge database, its available to nearly 200 countries, and it has registered 40 million stolen travel documents. But most countries simply wont be bother running the pass ports. The United States is the best, followed by britain and then the united arab imrates. Other interpol says it is a huge hole in security. Now to the tense situation in ukraine. Nato says it is flying reconnaissance flights over poe lacked and romania to monitor region. So far diplomatic efforts to resolving this crisis are falling flat. And just six days people of crimea are scheduled to vote on a referendum to join russia.

There is a real sense that it is only a matter of time before the russians take complete control. . This base ukraine ya yanl ukrainian soldiers are reinforcing their defenses. There is a new directive whether ukrainian soldiers stand outside or inside, guns must be at the ready. Pressure began last week, we fi filmed as a mob stormed the base. This is that same gate six days later, and it is more calm right now, but they have rep forced the gate with solders, and this gate is new, and over here they parked a heavy duty truck filled with cement blocks to block everyone from coming in. They still fly the ukrainian flag. They are so apprehensive of the russians out front they would only let me come if they snuck me over the back wall. This officer has four kids who live outside of the base. Most of these defenses were lasted 40 years ago. Translator it in slow them down. In a fight a few seconds can give you the advantage. Reporter his commander has been negotiating with the russians. He believes he has bought time, but he worries that time is running out. Translator my troops and i are all the time under pressure. There are different provocations, different ultimate tums. Reporter he shows me the latest. Stand down and hand over all weapons. Translator it is a real occupation, we shouldnt pretend otherwise. Reporter when the Russian Troops first arrived the ukrainians were under strict order not to shoot. So they resisted however they could. Today that order still stands. We are going to protect our base, absolutely. But not with gunfire. Reporter this major admit there is not much his troops can do to resist physically, so all they can do is resist the demand to standingdown. What was the response . Translator we are lawfully fulfilling our duty. Reporter but they are not sure how long this lock will hold. He hopes the deal he has made keeps the base safe at least until sunday. Nick schifrin thank you very much. Coming up, deep divide, reports of a growing riff when opposition heards in venezuela. And Edward Snowden says its all about the constitution.

This doctor convinced the state legislature to change the laws so Police Officers can administer the 20 drug. He says medically there is no down side. It is completely benign. The only function it has is to reverse narcotic overdose. If we sprayed it in the nose of season who doesnt have a narcotic problem, it would be like spraying saline or water. Reporter police used the drugs on 21 people in the first three months, 20 survived. A Smaller Community like this, it just takes off. That could be hundreds of thousands of lives eventually. Reporter the Obama Administration is pushing polices nationwide to arm their officers with nar cam, but the governor of maine vetoed a bill that would make it legal in his state, arguing it would give addicts a false survivor.
