York city cops. I cant breathe. Street protests expected today over whether officers used an illegal choke hold to bring him down. And killer caffeine. A teens death linked to a product 25 times more powerful than your morning coffee. What you need to know this morning about the fdas important new warning. Hey, good morning, everybody. Right to the breaking news on flight mh17. Ripped out of the sky over ukraine. Heres what we know. President obama pointing the finger at rebel fighters in Eastern Ukraine, fighters who are backed by russia, he says they used a russian made surfacetoair missile to shoot down the plane even perhaps with russian technical support. We also know one american was among the victims. Quinn Lucas Schansman was 19 years old with joint u. S. dutch citizenship, 1 of the 2 the 8 dead including 80 children. Three of whom were infants. Also this morning, growing International Outrage over the fact that rebel fighters in Eastern Ukraine were not allowing investigators to reach the scene of the crash. We have Team Coverage of what is a fastmoving story at this hour and begin with abcs kirit radia who was able to reach the scene and what he found was shocking. Reporter good morning. Im standing right in t the mide of where the bulk of the plane landed. As you can see almost nothing survived. Just a part of the landing gear, part of the engine and burned body parts everywhere. This morning, International Investigators complain that the rebels that control this area wont give them full access to the site. The smell hits you even before you see it. Jet fuel and death. The wreckage still smoldering. Every white flag a body part. Among the debris a childs toy, a backpack, someones suitcase. Anywhere else in the world the crash site would be roped off and crawling with investigators. Not here. Only a few rebels to keep watch and local emergency workers. International investigators still havent arrived. The team who arrived last night said the rebels did not grant them full access. President obama says the u. S. Has evidence the rebels shot the plane down. Evidence indicates that the plane was shot down by a surfacetoair missile that was launched from an area controlled by russianbacked separatists inside of ukraine. Reporter one rebel blasted those claims. [ speaking a Foreign Language ] reporter telling us it was the Ukrainian Military who did this. Among the dead an american student on his way to join his familys vacation. Its so senseless what happened. Reporter also killed three infants, almost bringing the u. S. Ambassador to the United Nations to tears. As we stared at the passenger list yesterday we saw next to three of the passengers names a capital i. As we now know the letter i stands for infant. Reporter back at the crash site the rebels say theyll facilitate an investigation. But so far that has yet to begin. Its been raining here today and all of this evidence and so many of the bodies are still laying out exposed to the elements. Now nearly 48 hours after the crash. Dan and bianna. A complete disrespect for the dead. Kirit radia, thank you. Lets bring in colonel Steve Ganyard in london. Steve, good morning. The fact that the crime scene is so to rowly unsecured. How badly does that set back the investigation . Dan, ive got a little bit of a different take on this. You know, i think the past 24 hours weve had the president come out and confirm and awhat happened. That is that a surfacetoair Missile System that was russian in origin brought this aircraft down and so i think we really know what happened. Getting to those black boxes isnt going to tell us much. The black boxes will only say this was a perfectly good airplane right up until the impact of that missile. Getting to the crash site could provide some forensic evidence, perhaps things like residue from explosives or some metal fragments but i think right now what we really need to do is get to the crash site and preserve some of the dignity of the dead and their loved ones. Hard to call that anything other than an outrage. Given this situation and given that were in an active war zone how do we get to the bottom of this and find out who is to blame . Right, thats going to be the challenge because we know that the rebels had this weapon, we know that it came from rebel territory and saw two weeks ago nato intelligence officials were briefing they saw the russians giving training to the rebels on this sophisticated tactical mobile surfacetoair Missile System. So there are lots of pieces of evidence now but i think were going to shift from a mindset of a Crime Scene Investigation to an intelligence investigation to try and figure out how was these missiles came to be into rebel hands and itll probably most likely point back to moscow. Why would it be in anybodys interest, though, to shoot down a commercial airplane . Why do youny they would have done this . Right now i can only imagine that it was not done delibera deliberately. If they were given a little bit of training they probably werent told how to use the capabilities of that system to determine the difference between a commercial and a military aircraft. They probably just saw a blip on the radar, locked on and pulled the trigger but i think what happened here is that mr. Putin gave some delinquent children a can of gasoline and matches and hes now shocked to find out that they started a fire. Horrifying. All right, colonel Steve Ganyard, our aviation consultanting reporting in from london this morning, thank you. Our thoughts and prayer, of course, with the loved ones who lost so many people and bears reminding this is a human tragedy. Nearly 300 lost souls and starting to hear some of their stories and the twist of fate surrounding that doomed flight. Circumstances keeping some people off the plane saving their lives while others wound up lastminute passengers. Abcs david wright has their incredible stories from kuala lumpur. David. Reporter good morning, bianna. Across this country, flags at halfstaff, people here still grab 8ing with the disappearance of Malaysian Air 370 now mourning the loss of flight 17 too and were hearing stories today from the lucky few, ticketed passengers who ended up not getting on board that plane. Barry and izzy sim tried to fly out on mh17 but the flight was oversold. There werent enough seats for them and their baby. I was going to change my luck to be on Malaysian Airlines and we couldnt get both on the flight this morning so we changed it to the klm one. Reporter that decision saved their lives. Just shock you get the sick feeling in the pit of your stomach. We were supposed to be on that flight and obviously, you know, something watching over us and say, no, dont get on that flight. Reporter australian newly wed simone and juan had tickets on mh17 coming home from their honeymoon. We have some pretty good guardian angels. And ended up flying home a day early worrying about getting over the jet lag for work. Feeling lucky but at the same time hard to believe for these families that, you know, expecting their loved ones to come home. Reporter Flight Attendant san ji singh swapped on to it in the last moment. In march his wife also a Flight Attendant swapped off flight 370. She lived. Hes gone. Marten is lucky twice. He was booked on both flights and ended up not boarding the fateful flight. Here in malaysia theres truly a sense that lightning has struck twice. The agony still fresh for those flight 370 families, now dozens more sharing their grief. Dan . Lightning striking twice, david wright, thank you. This is a disaster that could change the face of commercial aviation. The flight path over Eastern Ukraine was technically open for business on the day mh17 was shut down. Dozens crossed the space that day and planes regularly fly over war zones all over this planet so could this crash change that and what kind of impact will it have on us flyers. Jim avila is at Reagan National airport. Jim, good morning. Reporter good morning, dan. We board a flight we know where were going but we rarely think about the route the pilot is taking. For the shootdown of this passenger jet that may change. Add ukraine to a growing list of hot spots International Airlines are required to avoid. North korea, yemen, the Sinai Peninsula and syria. A big chunk of airspace. So why did Malaysian Air flight 17 pass over a combat zone thursday . Because that area wasnt closed down above 32,000 feet and the doomed 777 was flying at an unrestricted 33,000 feet when the missile brought it down. Abc news aviation consultant john nance says it may have been flying legally but it was still flying unwise. When youre flying over a war zone it doesnt matter if somebody says, well, youre okay above 32,000 feet. Maybe you want to be more conservative. Reporter after the missile strike all airspace over Eastern Ukraine was closed. An expensive detour for airlines who lose time, about ten minutes to fly around the combat zone and 1500 per flight in fuel costs. But despite the cost in time and money, this week, the biggest aviation lesson may be more caution from regulators and pilots in times of war. Weve got to be much more proactive about staying clear of any possible hot zone in terms of combat on the ground. Reporter but in the air all those simultaneous war zones on the ground carve out thousands of miles through a popular air corridor with some of the worlds heaviest traffic. Pilots, passengers and airlines thinking a lot more about whats below us as we fly in the air. Dan. Thinking a lot more about that flight path. All right, jim, thank you.
