Now, despite reports of debris sightings and oil slicks, officials in malaysia say they have not seen evidence of the jet. The possibility of terrorism now in the mix. Brooke will look at that in the moment. Lets bring in jim clancy, live from kuala lumpur. Reporter hopes, fear plus frustration more than 60 hours after this fly vanished off the radar, the mystery of what happened to this flight still eludes us but people are not giving up. This morning the search intensifies for missing Malaysia Flight 370. Now three days into this exhausting hunt for clues, they are scouring the waters of the south china sea. Malaysias Civil Aviation chief says no wreckage has been found. We have not found anything that appears to be objects from the aircraft, let alone the aircraft. Reporter but he did confirm they have taken samples from a spotted oil slick between the waters between malaysia and vietnam in hopes of a positive match. Teams all involved in the search effort with more than 30 aircraft and some 40 ships across at least 50 nautical miles. The missing boeing 777 took off on saturday. Less than an hour after takeoff, the tower lost the planes signal. No distress call sent and the weather clear at the time. The boeing 777 and its 239 people aboard seemingly vanished. Despite the lack of clues, officials here say they have some clues. We look back at the recording and there is a possible indication that the aircraft may turn back. Reporter investigating the possibility that the flight may have changed course and tried to turn back. Adding to the mystery, interpol says two of the passengers used stolen passports. Now theyre examining Surveillance Videos and additional suspect passports. This Facebook Page has been dedicated to the 239 people who the airline says belong to 14 different nations. Three americans were on board, including 50yearold phillip wood from north texas. More than half of those aboard that jetliner were of chinese descent, they were chinese nationals and they have begun arriving here in kuala lumpur. They are searching for their Family Members and searching for answers. There are no answers here, at least not yet. Jim clancy, thank you so much. If terrorists had anything to do with the disappearance of this flight, theyre not taking credit like they usually do. Right now officials are focusing on the two passengers who got on the boeing 777 with stolen passports. Lets bring in pamela brown on that angle. Reporter good morning. Right now interpol trying to identify the two passengers who used the stolen passports. The question remains how did they board that plane and another frightening thought, how often does that happen. According to interpol, an astounding number of people have boarded flights without having their passports checked as lost or stolen. Its one of the biggest mysteries in the disappearance of Malaysia Flight 370. How did two passengers board a flight with stolen passports . Even more surprising, they were in plane sites, among the names listed in the stolen passports list. When you book your ticket, the airline is not able to make an inquiry with interpol about whether youre wanted or whether the passport has been reported stolen. The country the government does. Last year alone, passports were able to board planes without having their passports screened against interpol databases more than 1 billio times. The member countries, the 190 members that belong to interpol, are not charged a fee for accessing any of those databases. So if the country has sufficient resources and Technical Capability to wire into interpols Virtual Private Network thats running 24 hours a day, they certainly would be able to access that database and check it. Its up to the will of the country to set it up and do it. Ronald noble says now we have a real case where the world is speculating whether the stolen passport holders are terrorists, while interpol is asking why only a handful of Countries Worldwide are making sure that people possessing stolen passports are not boarding flights. How often do officials get a hit for stolen passports . More than 60,000. Mr. Mcgau, thank you. Good morning. Its a big plane. How unusual for there to be no signal or sign or communication from such a sophisticated jet . Its very unusual. It has to be something that is sudden and violent. Also, why season the transponder working so that it can be located . Those are big concerns. But it had to be something quick, violent that took it out of the sky. Lets get perspective on whether you think these are real clues or could be red herrings. We have the missing passport, the oil slicks and the dramatic turn on the end on radar back toward kuala lumpur. What do you make of those . Well, in terms of the turn back towards kuala lumpur, i think in bombings before in aircraft, if this is a bombing where one side of an aircraft is blown out, sometimes it will, my understanding, cause it to veer right before going down or virtually at the same time. I think this is something obviously were going to have to look at closer. But if it was turning around on its own and intentionally, then why no warning, why no mayday and why is there a closer airport than turning around. Those are all things that have to be answered. The oil slim. We now believe it may not be from this plane, it could be from Something Else, that it was so long and it was sitting there with no debris field around it, does it make as soon as now that its as likely that its associated as unassociated . Its think it may be 50 50 or 60 40 it is the debris of that plane. The oil is going to come up, parts of the airplane are pinned down and there are parts that are float. And the fact that its such a long area is typical if its an explosion. And talking about the oddity of this, you have almost no aircraft accidents historically, very few, at that level. Was it something that was in the cargo hold that triggered at 35,000 or 36,000 feet. That was an important point, mr. Magaw, unusual that you have major malfunctions at that height. The passports, the more we learn about it, the less impressive it becomes. It wont be surprising to investigators or those who are in the business. Thats been a concern for a long time. And ron noble from interpol has expressed that. But youve got fugitives that are using them. You have human trafficking. You have drug trade. You could go on and on as people who are using false identification. And now youve got four on the aircraft that used false identification. So its not unusual in that part of the world for virtually all the flights that have any number of passengers, it not unusual that you might find one thats improperly identified. So probably more interesting than it is instructive. And lastly, if this were terrorism, is it unusual that whoever did it wouldnt have wanted people to know they had taken control of the aircraft and that a group wouldnt have come forward now saying, yes, it was us . Well, since 9 11 and since afghanistan, you have had a lot of it spread out throughout the world and also here in the United States were very concerned about the two or three or four people who plan the event because theyre much more difficult to identify but theyre well to be. But youre right, you dont want tunnel vision with the improper identification here. How about those ground crews . Who handled that aircraft from the time it arrived on the ground until it left. You have caterers, you have mechanics, baggage handlers, ramp managers. Who has access to that ramp. Weve had problems with country with ramp side access not well protected and were dealing with that now. But in Foreign Countries and other countries, were still having a big problem with that. The cleaners in the aircraft can insert something underneath the cushion that detonates at a certain time or put in the cargo hold. There are just so many possibilities here. But it really is catastrophic. I dont think theres much question in anybodys mind if that are really straight forward that it wasnt catastrophic. The search for answers is very important for investigators. But for those 239 families, the answer couldnt be more urgent than it is and our thoughts are with them obviously. Mr. Magaw, thank you for the insight this morning. Youre welcome. Brooke . Even as the world warns Vladimir Putin to stay back, the russian buildup in crimea shows to signs of slowing down. Prorussian supporters went on the attack. Cnn has exclusive pictures of where the battle lines are being drawn. Hundreds of troops have built this new border complete with mine fields, barbed wire. What theyre doing is looking to establish control with a referendum on crimeas future. All of six days away. We want to get more on that. Anna, good morning. Reporter hi, brooke, thats right. Less than a week before the referendum here in crimea, that military buildup of Russian Forces has definitely intensified. Were getting reports theyre creating a new border between crimea and ukraine so we drove up and this is what we found. Parked along the highway linking crimea to ukraine, a convoy of Russian Military trucks and armored personnel carriers. Were approaching a check point flying the russian flag where troops are searching cars, targeting media crews and confiscating equipment. We hide our cameras as soldiers inspect the van. One of them is spotted. Its taken and turned off. This is now effectively part of russia and they dont want us filming the evidence. The local soldier in charge, who sworn allegiance to russia, agrees to an interview. Were defending our people, he tells me. This is not about russia but protecting our homeland. We see a new border being erected. Once out of view from Russian Troops, we stop the car and continue filming. Russian troops is dug in armed personnel carriers have rolled out barbed wire, dug fence posts and will are also signs that indicates there are land mines in the area. A local resident says this is a mine field. A neighbors dog ran through and was blon up. Blown up. Several miles away, they, too, are setting up camp, well aware it could turn bloody. If they want us to defend crimea, we will do this and we will die, this soldier says. We know theres a media crack down on the way. We were lucky, we did not have our equipment confiscated but they dont want us recording the buildup of the new border. But from what we could see, they are digging in and the russians are here to stay. Anna coren. Thank you. A powerful 6. 9 magnitude earthquake hit 50 miles west of eureka and humbolt county.
