BERMAN: New details this morning on what led to the downing of Malaysia Airlines Flight 17. The Dutch Safety Board releasing a preliminary report after combing through data, satellite images and more. So what do we know now and just as importantly what answers remain elusive? CNN's Richard Quest has the report in his hands. He's been looking through it. He joins us now from Atlanta. Good morning, Richard.</s>RICHARD QUEST, CNN AVIATION CORRESPONDENT: Good morning, John. The startling thing about this report is it says everything and yet it never actually uses the word missile once. It tells us that it was -- the plane was brought down by high energy impact. It was brought down by external causes. It talks -- says there was no technical malfunction and that the plane broke up in midair. Put this all together and, of course, what it is saying, is that a missile brought down the aircraft MH-17, but never actually uses the word because it's the job of this report to discuss what happened and how to prevent it happening in the future. Not to apportion blame -- John.</s>BERMAN: And the black box was not tampered with in any warning to the pilots, Richard, before the blast?</s>QUEST: We know the black boxes weren't tampered with because their unique digital signature was valid. The integrity was maintained to that aircraft. No warning at all. Particularly haunting the way in which, John, we just know at 1320 GMT, transmissions stopped. And it was a Russian air traffic controller who commenting afterwards to another air traffic controller said, the digital -- the radar signature, it just disappeared.</s>BERMAN: Haunting as you say. Richard Quest for us in Atlanta. Thanks so much. Fifty-three minutes after the hour right now. A fourth American infected with Ebola and on the way home to the United States. What we know about this latest American case next.
