Transcript for Cellphone Video Captures Malaysia Plane Crash
Reporter: Good morning. A team of international investigators is on their way to the crash site. Their safe passage and access to that debris field has supposedly been guaranteed by the rebels who control that territory. This is a race against time, aviation experts say, to preserve the credibility and the accuracy of any investigation. This morning in Ukraine brought a clearer look at the ghastly scene, the charred remains of Malaysian airlines flight 17 and the 29 souls on board. The wreckage across ten miles of countryside and this the moment of impact, the huge Boeing 777 slamming into the ground sending up plumes of smoke and those white streak, pieces of the plane raining down. It was 4:20 P.M. Local time. Four hours earlier flight 17 took off from Amsterdam bound for Kuala Lumpur in Malaysia carrying enough fuel for the 11 1/2-hour flight then traveling at 33,000 feet crossing over war-torn Ukraine, the plane is apparently struck by a surface-to-air missile and loses contact with ground control some 30 miles from the Russian border crashing into rebel-held territory. Authorities say, no distress call came from the pilot. Our reporter John Wendell was on the scene amid the carnage. We found part of the tail fuselage. There is a body next to it. It is a very grim scene. Reporter: The bodies rained down from the sky, witnesses said, passports, boarding passes, belongings falling with them, relics of 298 lives including three newborns. As the wreckage smoldered back in the U.S. Talk quickly turned to terrorism. Shot down, not an accident. Blown out of the sky. Reporter: The question this morning, who fired that missile if that's, in fact, what brought down the plane? Ukraine's president blaming pro-russian rebels saying "We're not calling it an accident or disaster but an act of terrorism" but those pro-russian separatists say it was the Ukrainian forces who shot down the plane and Russian president Vladimir Putin says the state over whose territory this occurred bears responsibility for this awful tragedy. As for the plane's two black boxes that rebels claim to have recovered there are reports at least one of them may have already been sent to Moscow. That's obviously crucial. Whoever controls the data here controls the investigation and the story of what happened to Malaysia airlines flight 17.
