Democrats. This time Hillary Clintons campaign targeted. Are the russians behind it . And the scare at the beach. Dozens of people stung by stingrays. Almost invisible until its too late. Good evening and thank you for joining us on this saturday. Im cecelia vega. We begin with the breaking news, a horrific scene unfolding in texas right now. A deadly hot air balloon crash that left 16 dead and there are no survivors. Investigators say the balloon caught fire in midair possibly hitting power lines, plunging to the ground in an open field. Federal investigators arriving at the scene. It is a remote area. 30 miles outside austin for what is now this countrys deadliest hot air balloon crash ever. Our david kerley is standing by but first Christine Dobbyn from our houston station starts us off right there on the scene. Reporter a bystander capturing these images just before the joyride went terribly wrong shot from a ride at 7 30 this morning. Flying low over farmland in texas. A vehicle fully engulfed in flames. The 911 calls coming in six minutes later describing the balloon hitting power lines and exploding in flames. These pictures showing the flattened balloon in lockhart, texas, 30 miles from austin. The popping sound was the balloon connecting with the electric lines and by the time i turned and saw the fireball go up, the basket was on the ground. Investigators going through the remains of the basket and balloon. The faa confirming all 16 aboard perished. You could tell it was a fire. You know, a big ball of flames and you could tell nothing what it was or anything. The balloon was operated by heart of texas hot air balloon rides, the company is owned by skip nickels who regularly celebrates his love of flying posting photos and videos on facebook. Tonight tributes are pouring in remembering a quote, great pilot and a man who had a happygolucky outlook on life. Cecelia sources say the pilot would fly five to seven miles during one hour flights. At times flying seven days a week. Cecelia. Christine, thank you. As we said, this is the deadliest balloon crash ever in this country. Federal investigators from three agencies are rushing to the scene. Abcs david kerley has the latest on the investigation and the difficult work ahead. Reporter a full team, 13 ntsb investigators will arrive at the site of this hot air balloon tragedy in texas. That loss of life unprecedented in u. S. History. It is a scene investigators have seen before. Hot air balloons coming into contact with power lines. Often resulting in fire and death. A honeymooning couple indiana survived back in 2014. When we hit the pilot told us to get down. So we were all crouched down in the basket. All we saw was sparks fall around us and felt the sparks. Since 1969 there have been nearly 70 fatal balloon accidents killing 116 before today. Often commercial pilots try to land near roads to easily transport riders but many times power lines are nearby. If youre trying to land the basket or balloon near a road its often times going to require you to either skip over or land close to high tension power lines. While the pilot of this balloon was experienced, it was a large balloon. 8,500 cubic meters able to carry 16 people. That large of a balloon takes a bit more time to rise or descend. Safety investigators called a regular lugs of the balloon to our industry. The ntsb two years ago sending a letter to the faa saying it found operational deficiencies in air balloon operations and said there is a lack of oversight. The faa did not increase regulation of the industry. Its one of those times where the faa needs to say are we regulating this industry close enough . Is it safe enough that we can tell people were doing everything we should be doing in terms of keeping them safe . David kerley covers transportation and joins us. That team of investigators on the scene. Can you tell us what clues they will be looking for . Reporter theyll be looking at the weather cecelia, what was the flight plan of the pilot, his experience, what had he done in the past 24 hours and theyre also going to want to know the regulations are in place, were they followed during this flight. Cecelia. So many questions still, david. Thank you. And now donald trump at the center of a new firestorm tonight. One of the most powerful moments of the democratic convention. Those muslim parents of a fallen american soldier. The father delivering a pointed speech aimed directly at trump. But now trumps response in a one on one interview with George Stephanopoulos drawing outrage from liberal and conservative critics alike. Abcs mary bruce has more. Reporter donald trump is sparking outrage and disgust with his response to this grieving father. We are honored to stand here as parents of captain khan. It was the most raw emotional moment of the convention. Offering this searing rebuke of trump. You have sacrificed nothing. And no one khan, an army captain, the son of muslim immigrants died serving his nation in iraq. His father challenging trump. Let me ask you have you even read the United States constitution . [ cheers and applause ] i will gladly lend you my copy. Tonight trump responding in an exclusive interview with George Stephanopoulos saying that like the khans he too has sacrificed. I think ive made a lot of sacrifices. I work very, very hard and created thousands and thousands of jobs. Tens of thousands of jobs. Built great structures. Ive done ive had tremendous success. I think ive done a lot. Those are sacrifices . Sure, i think theyre sacrifices. And pointing a finger at captain khans mother suggesting she did not speak because she was forbidden by her faith. If you look at his wife she was standing there, had nothing to say. Maybe she wasnt allowed to have anything to say. The real reason she tells us. All consuming grief. I was in pain. And all american feel that pain of us. So much internet. I give them this faith. Cecelia, its not just the khans upset, the social media the response is explosive and furious. Trending on twitter made a lot of sacrifice. Cecelia. You can see georges interview with donald trump tomorrow on this week. To the democrats coming under fire not just in the race for the white house but by hackers. The Clinton Campaign falling victim in a new attack. The big question tonight, are the russians behind it. Today clinton on a bus trip through the battle grounds states of pennsylvania and ohio, her husband you can see right there with her. And abcs david right is on the campaign trail tonight. Reporter authorities are trying to determine if the same Russian Hackers also gained access to software under the Clinton Campaign. It all may sound like the plot of a cold war spy novel. Cia director James Brennan said its not so farfetched. If theres been manipulation of the election pro sense and system here, this is going to be something that this government and our country is going to have to look at. Reporter the emails from the dnc brought havoc at the Democratic National convention forcing the party chair to resign. The threats are real and getting bigger every year. Reporter becoming an issue on the campaign trail. Donald trump is sought to link the hacking over Hillary Clintons private email server. Russia, if youre listening i hope youre able to find the 30,000 emails missing. I think you will probably be rewarded mightily by our press. Reporter the Trump Campaign now says this seems to be a problem wherever Hillary Clinton goes. Hopefully this time there wasnt classified or top secret information that puts american lives at risk. The Clinton Campaign says the best they can tell the hack was limited to a program used to examine publicly available voter data. Insist all of their internal systems are secure. But as Hillary Clinton continues her bus tour through today she herself hasnt been discussing the topic. Leaving it to others. Cecelia. No mention of it tonight. David, thank you. To europe now.

Reporter in miami extra patrols screening residents and passing out critical supplies in the trouble zone. Officials in miami confident they can keep zika contained. Once something starts, we nip it in the bud. Health officials are really encouraging people who live near mosquitos anywhere, not just this neighborhood, to exercise caution and wear repellant. Cecelia. Eva, thank you. I want to bring in abcs chief medical editor dr. Richard besser from brazil, the center of the outbreak. Tonight you heard it, england saying pregnant women should not travel to florida but the cdc not issuing the same warning. Is that a mistake . I have to say if these cases had occurred were the first cases in the caribbean country or latin america they would issue that advisory but what theyre saying is four cases that occurred in early july and no transmission since then, but i have to say if youre a pregnant woman and can avoid that part of miami, thats not a bad idea and if youre pregnant and live there, you want to make sure youre using repellant all the time. We want to turn to san diego.
