team taking on the boys, already in a league of their own. >> i want to beat the boys! >> let's go peaches! >> good evening. thank you for joining us on this saturday. i'm cecilia vega, and we begin tonight with the mystery of egyptair flight 804. we are hearing for the first time the pilots' radio calls and now the new clues. we know there was smoke on that plane during its final moments. so was there a mechanical failure too? today the egyptian military gathering pieces of debris floating in the sea. among them mangled parts of the plane itself. there at the left, a child's pink backpack. those objects signs of the lives lost. and we are learning more about those passengers tonight, too, including the parents on their way home, their children waiting for them at the airport. abc's matt gutman starts us off from cairo. >> reporter: as the physical

remnants of that doomed plane were laid out on a ship, tonight we hear for the first time the voices of the men flying it. >> hello, hello, egyptair 804 flight level 370, squawk number 7624. >> reporter: that's a recording of the flight deck's communications with the air traffic control tower early thursday. their final words chillingly mundane. >> thank you so much. good day. have a good night. >> reporter: minutes later that plane would disappear from radar, cause still unknown. what was apparent today the violence of that breakup. the grisly haul spotted from the air and scooped up by small inflatables like this. it included parts of the plane itself. twisted pieces of metal with the egyptair logo. the shredded and waterlogged remnants of a seat, a life jacket that was never inflated, and also the possessions of the people it carried -- clothes, a purse. tonight the search for more of the wreckage ramping up in its third day aided by 24-hour-a-day flights by u.s. aircraft using sophisticated equipment to scan the water.

and now abc news has learned ships able to scan the ocean floor also sailing into place hoping to find the black boxes. which could be in water 10,000 feet deep. as search crews scour the area, families mourn. grief bringing this grandmother to her knees, and three children who waited to greet their parents at the airport, their mother was returning triumphant after successful cancer treatment, only that plane never landed. this has shattered all hope anyone could have survived. the reason the plane went down still very much a mystery tonight. isis releasing a 30-minute die tribe against the west but not claiming responsibility for bringing the plane down. cecilia? >> so many questions. matt, thank you. next to the search for answers about what happened to that flight. investigators are now looking closely at alerts indicating there was

and that is raising new questions about what may have caused flight 804 to come down. abc's david kerley with that part of the story. >> reporter: it could have been smoke, even fire rather than a bomb that brought down the egyptair jet. >> could a fire actually overtake the crew in a matter of moments? >> the smoke could. the smoke is what gets to -- what brings airplanes down when there's fire in the cockpit. >> reporter: the airbus was equipped with a transmission system which sent seven messages in the final moments of the flight. alarmingly, one message came from the avionics, the equipment bay. this is where the leks tronices are housed. that bay is right below the cockpit in the forward lavatory. at 2:26 a.m., messages sent to the satellite and the pilots. window sensor warnings. seconds later this pops up, lavatory smoke. then only a minute passes and another message, this time avionics smoke. at 2:29 signals warning of trouble with the flight control systems, and then, nothing.

the a-320 disappears from radar. >> if it was a bomb, could have been a bomb, it would have been something that would have caused a fire, not a blast. also it's very difficult to get this kind of bomb in the avionics bay. >> reporter: it's those black boxes now on the bottom of the mediterranean which will tell us exactly what happened. listening equipment like this will likely be deployed soon when searchers think they are near the wreckage, listening for those black box pingers. their batteries may die as early as three and a half weeks from tonight. if it turns out to be mechanical electrical issue, that would be a major concern because the a-320 is one of the most popular jet liners in the world. nearly 7,000 have been delivered by airbus. cecilia? >> a concerning prospect indeed. david kerley, thank you. next to that scare at the white house. an armed man at a security check point refusing to drop his weapon. then shot by the secret service. it happened yesterday afternoon. the president was not there at the time.

jesse olivieri of ashland, pennsylvania. he is in the hospital. no word yet on a motive. and we do have breaking news from the racing world to tell you about. two horses dying on the same day just as crowds gathered ahead of the preakness stakes. the second leg of the triple crown. as abc's ron claiborne reports, the same thing has happened at this track before. >> reporter: it was the first race at pimlico on preakness day. >> homeboykris gets home to win it by a head. >> reporter: the winner, a 9-to-1 longshot named homebykris. the 9-year-old showing no signs of trouble as his jockey walked him around the track afterward, but minutes later on his way back to his barn, homeboykris collapsed and died. three races later, misfortune struck again. this time a 4-year-old filly named pramedya went down mid-race with a fractured front leg. she was euthanized right on the track. her jockey suffering a broken collar.

>> it's just so untimely and so unfortunate to have two horses lose their lives when the world really is watching on maryland's biggest day of racing. >> reporter: in a tragic twist pramedya's owners also owned barbaro, the kentucky derby winner who shattered his leg here ten years ago. and had to be put down seven months later. horse racing is an arduous, risky sport. nearly 500 racing horses die each year. tonight that danger highlighted on one of the sport's biggest days. an autopsy will be performed on homebykris but a heart attack is what's suspected. tonight his owner saying in a statement, "kris had a small team who loved him. we are all just heartbroken." cecilia? >> okay, ron, thank you. we turn next to the race for the white house. guns at the center of the debate tonight. donald trump saying hillary clinton's stance on guns means she does not deserve secret service protection. this a day after his big meeting with the nra. clinton tonight holding a

meeting of her own with victims of gun violence. here's abc's david wright with the latest war of words. >> reporter: one day after locking up the endorsement -- >> crooked hillary clinton is the most anti-gun, anti-second amendment candidate ever to run for office. >> reporter: donald trump aimed an outrage is tweet at his likely democratic opponent, suggesting her secret service detail lay down their weapons. crooked hillary wants to get rid of all guns, and yet she is surrounded by bodyguards who are fully armed. no more guns to protect hillary. it's an idea he first raised in the nra speech. >> let's see how they feel walking around without their guns on their bodyguards. >> reporter: clinton has made reducing gun violence a centerpiece of her campaign in ads such as this one. >> she is the only candidate that has what it takes to take on the gun lobby. >> reporter: she's never said that gun ownership should be banned. she has called for stricter

background checks, more accountability for gun manufacturers, and stronger efforts to keep guns away from terrorists, violent criminals and the mentally ill, tweeting, "you're wrong, donald trump. we can uphold second amendment rights while preventing senseless gun violence." tonight she's a keynote speaker at an event with mothers who lost their children to gun violence, including trayvon martin's mom. her son, killed by george zimmerman in 2012. clinton's views on guns have remained pretty consistent. trump's not so much. in the past he's been critical of the gun lobby, and while he told the nra he would get rid of gun-free zones. he might have to start with some of his own properties. cecilia? >> david wright, thank you. we turn to a major development from the conflict in afghanistan and pakistan tonight. a u.s. official saying the head of the taliban was targeted and likely killed in an air strike. mullah mansour was reportedly

by u.s. special operations forces in a remote area of pakistan. the strike authorized by the president. next to the zika emergency. the number of pregnant women with the infection suddenly tripling. the cdc had been reporting 48 pregnant women with zika here in the u.s. tonight that number jumping to 157. and now a new country facing an ominous prospect. abc's gio benitez reporting in from miami. >> reporter: tonight a baby in yet another country may have the birth defect caused by zika. if confirmed, costa rica would become the 9th territory to have an infant born with an abnormally small head linked to the virus. this comes after the cdc's release of troubling new numbers friday. pregnant women in the u.s. and puerto rico infected with zika spiking to nearly 300 cases. the reason for the jump? the cdc was not including women who showed no symptoms. they now acknowledge those

risk of having a child with a birth defect. >> they can have an asymptomatic infection, but this can still affect their newborns. >> reporter: sara mujica is the first pregnant american woman with zika who has come forward after contracting it in honduras. >> it was just like such hard news to take in all at once and my first thought was "what am i gonna do? and i asked my mom what am i gonna do?" >> reporter: she's now decided to have her baby. cecilia, what's so concerning to doctors right now is that women are being infected in puerto rico. that's just 1,000 miles away from here, not such a distant threat anymore. cecilia? >> gio, thank you. we want to turn now to record deadly heat in india. temperatures in the northwestern part of the country reaching almost 124 degrees in recent days, breaking a 60-year record. that hot weather blamed for hundreds of deaths.

degrees every day for weeks now. relief not expected until next month when monsoon season begins. here at home wild winds are fueling erce wildfires. in arizona's mow javy valley. you can see this thick black smoke right there billowing across the desert, evacuations ordered. officials blamed a downed power line or a transformer for that blaze that has now devoured 400 acres and counting. next to the severe weather. a tornado watch in three states at this hour, and now the threat of thunderstorms in the plains, too. take a look at this, up to 8 inches of hail falling, that's in the black hills of south dakota. some tough driving there. abc meteorologyologist indra petersons is tracking it all. that didn't look like spring and you're watching even more. >> almost looked like snow. the jet stream has dropped far south in the west. that means that cool air is banking against the heat in the

plains and that clashes causing all that instability. tonight looking at tornado watches. focusing on eastern colorado as well as the texas panhandle. as we go through this evening and tomorrow, look at the difference. we're talking about the system expanding from texas through the dakotas. this is the epitome of tornado ally. we're not just looking for the severe weather with thunderstorms but also the threat for tornados. this threat continues through the middle of next week. >> rough weather ahead. indra, thank you. some rough going at america's airports tonight. long lines of weekend travelers snaking through the airport in atlanta just waiting to get through the security check. now the head of the tsa with a dire warning, summer travel will not get much better. here's abc's mary bruce on one way fliers are getting through those long lines just a little faster. >> reporter: one week out from the memorial day rush, travelers are bracing themselves for more of this. in seattle, marathon lines.

>> reporter: the same problem in charlotte. >> look at the chaos that goes on here. >> reporter: and in chicago where it's been the worst, travelers are giving themselves plenty of time today. >> they told us to come early because it's taking so long. there was nobody here. >> reporter: but don't expect that to last. this summer 2.5 million of us will fly every day. >> the summer is going to continue to be a challenge. >> reporter: the tsa is adding over 760 agents but they say that's a drop in the bucket. to fix the problem for good, they say they need more money. >> they have to move faster. therefore, something's going to gif sooner or later. >> reporter: at least one airport is taking matters into their own hands. in seattle they've hired 90 contractors. and fliers are flocking to tsa pre-check. enrollment for the $85 program doubling in the last month. a whopping 16,000 people are signing up on average each day. the tsa is encouraging travelers to sign up for that pre-check. but now even some of these preferred security lines are

reportedly getting backed up. cecilia. >> that is not good news. mary, thank you. still ahead on "world news tonight" this saturday, new developments in the death of music legend prince. how long did it take investigators to find his body? and drivers taking on and taking off after other drivers, shaming them for being distracted. so are they vigilantes or good samaritans? you both have a perfect driving record. perfect. no tickets. no accidents. that is until one of you clips a food truck, ruining your perfect record. yeah. now you would think your insurance company would cut you some slack, right? no. your insurance rates go through the roof... your perfect record doesn't get you anything. anything. perfect. for drivers with accident forgiveness, liberty mutual won't raise your rates due to your first accident. see car insurance in a whole new light.

tion. once i left the hospital after a dvt blood clot. what about my wife... ...what we're building together... ...and could this happen again? i was given warfarin in the hospital, but wondered, was this the best treatment for me? i spoke to my doctor and she told me about eliquis. eliquis treats dvt and pe blood clots and reduces the risk of them happening again. not only does eliquis treat dvt and pe blood clots.

bleeding than the standard treatment. knowing eliquis had both... ...turned around my thinking. don't stop eliquis unless you doctor tells you to. eliquis can cause serious, and in rare cases, fatal bleeding. don't take eliquis if you have an artificial heart valve or abnormal bleeding. if you had a spinal injection while on eliquis call your doctor right away if you have tingling, numbness, or muscle weakness. while taking eliquis, you may bruise more easily... and it may take longer than usual for bleeding to stop. seek immediate medical care for sudden signs of bleeding, like unusual bruising. eliquis may increase your bleeding risk if you take certain medicines. tell your doctor about all planned medical or dental procedures. eliquis treats dvt & pe blood clots. plus had less major bleeding. both made switching to eliquis right for me. ask your doctor if it's right for you. this clean was like - pow. everything well? it felt like i had just gone to the dentist. my teeth are glowing. they are so white. 6x cleaning*, 6x whiteningá*
