world a lesson in courage, will, and hope. this, as we learn new details about just what happened on that high-speed train. headed from amsterdam to paris friday night with more than 550 passengers on board. the three americans were on a european vacation when they spotted a gunman on their train. coming out of the bathroom, armed with an ak-47. >> alek hit me on the shoulder and said, let's go. we ran down. tackled him. we hit the ground. alek grabbed the gun. while i put him in a choke hold. >> reporter: a fourth american was the first to confront the gunman. he grabbed the ak-47, disarming him. he didn't realize the gunman had a pistol. mugalian turned to protect his wife and got shot in the back. the bullet, puncturing his lung, an unsung hero until now. that's when the other three americans leapt into action. >> i was able to grab him again. and choke him unconscious while alek was hitting him in the head. >> reporter: they grabbed the pistol. the gunman fought back with a box cutter. >> it seemed like he kept pulling more and more weapons left and right. pulled out a handgun. >> reporter: i gather after you were injured, you administered first aid to one of the passengers? >> i just stick two of my fingers in the hole, found what i thought to be the artery, pushed down and the bleed egg stopped. >> reporter: that moment caught on camera on a cell phone. the gunman subdued. tied up with a train conductor's necktie. french authorities have identified the gunman as ayoub el khazzani. a 25-year-old born in morocco. france had him on a watch list for more than a year after spanish authorities told them he was an islamist extremist. >> it feels very unreal. feels like a dream. so -- i don't really know what to say. >> reporter: el khazzani is being held without charge. french authorities have until tomorrow to charge him. meanwhile, the three americans are living just down the block at the american ambassador's residence. one of them told us, he's

biden serious about the run to the white house. he held a secret meeting with elizabeth warren as he pondered a challenge to hillary clinton. jon karl with the latest details from the white house. good morning, george. >> reporter: this was a meeting between the two democrats who could potentially pose the greatest threat to hillary clinton. the most intriguing sign yet that biden may actually run. it was a hastily arranged political meeting between the two biggest democrats not in the 2016 race. vice president biden left his vacation saturday. returned to washington, for a private, one-on-one meeting with liberal firebrand, elizabeth warren. >> welcome, welcome. >> reporter: the meeting, requested by biden, comes as the vice president is seriously considering whether to take on hillary clinton and jump into the 2016 presidential race. many on the left practically begged warren to make her own presidential run. she's ruled that out. but she's also refused to endorse any candidate so far, as she told boston station, wbz on friday. >> was it a mistake for your party to anoint her as the nominee? >> i don't think anybody has been anointed. we see all the candidates lay out where they stand on key issues. >> reporter: continuing questions over clinton's use of private e-mail as secretary of state may provide an opening for the vice president. a recent poll found only 37% say clinton is honest and trustworthy. in comparison, a strong majority say they trust biden. biden's backers are now touting him as more authentic than clinton. >> he knows that the american people, i think, are looking for authenticity in their presidential candidates this year. that's joe biden. the original authentic candidate. >> reporter: but donald trump told george sunday a biden run wouldn't make a difference. >> would he be a tougher opponent than hillary? >> i don't think so. i think they're the same. >> reporter: well, there may be an opening for another democratic challenger for hillary clinton, there's no sign of a ground swell for biden. in fact, in every major recent poll, biden comes in third among democratic voters, trailing not just hillary clinton but also bernie sanders. >> okay, jon. thanks. he has a lunch with the president today. would like to be a fly on the wall at that one. now to an air show disaster. a horrible accident killing at least 11 people on the road, after a pilot appeared to lose control of the vintage plane, crashing into a busy highway. crews are still going through the wreckage. terry moran is in london with that story. good morning, terry. >> reporter: good morning, robin. police say the death toll from this mohorrific crash now at 11. that could rise. and many here are asking angry questions. look at this. why did they have to die? from "the mirror." and they're calling for restrictions on these air shows. this morning, a grim task. workers will lift the wreckage at the hellish scene, looking for more victims. the worst air show accident in britain in more than half a century unfolded in cloudless blue skies as crowds of spectators and locals looked on in horror. >> oh! >> oh, no. >> reporter: the plane, a 1950s-era hawker hunter t-7. the pilot, 51-year-old andy hill. trusted british airways captain and a veteran stunt flyer. trying to make a thrilling loop, failing to pull up, the plane exploding on to a busy nearby highway. the pilot survived. he's in critical condition at a local hospital. it's the latest horrific incident at an air show, triggering a sharp question. are the thrills at these events worth the risk? 2011, reno, nevada, ten spectators killed. 70 wounded. 2002, ukraine, 77 people killed, among them, 28 children and more than 500 injured. just yesterday in switzerland, one day after the crash in britain, at least one dead when vintage planes collide during a stunt. >> air shows are inherently dangerous. they're exciting. there are aircraft doing things fast, low to the ground in close formation. so mishaps are going to occur. right now, they're above a level that's acceptable. >> reporter: the government's launched an investigation. one proposal out there, ban air shows over land. all these stunts would have to take place over open water. robin? >> we'll see if that happens. all right. terry, thank you. to amy for the morning's other top stories, starting with a race car driver fighting for his life this morning. >> that's right, robin. another serious crash on a racetrack. this time in an indycar race in pennsylvania. the yellow and red car spinning out. debris hits driver justin wilson in the head. he is now in a coma in critical condition. police in boston say they have foiled a violent plot against a pokemon convention full of children. they found these weapons in the car the two suspects had driven from iowa, including a shotgun, rifle, and hundreds of rounds of ammunition. one suspect allegedly posted a threat on social media last week against the event. and in louisiana, police say two passing drivers helped tackle a man who shot a state trooper in the head at a traffic stop. the suspect had allegedly been driving while impaired, was stuck in a ditch before then opening fire. trooper stephen vincent, a 13-year veteran of the force, is now in critical condition. overseas, new worries about isis destroying priceless ancient artifacts. mill militants reportedly destroyed one of the most important temples in the syrian city of palmyra. the explosion also damaged some of the city's famed columns. it was a photo finish for the world's fastest man. sprinter usain bolt raced from behind to win the 100-meter dash in the world championship, edging out american justin gatlin by 0.01 of a second. and finally, if you were wondering what jon stewart has been up to since leaving "the daily show," feast your eyes on this. while hosting an event called summer slam, he did some slamming of his own, invading the ring and smashing wrestler john cena with a folding chair. we all know stewart is say sharp guy. he got out of there quickly. here's something we also all know, guys. that was completely real. >> yeah. >> it was not planned. it just happened. no one's going to touch that? >> no. >> no. >> let that one go. >> just talking about jon stewart. we're going to move on to new calls for safety at baseball stadiums across the country after scary scenes at two more ballparks this weekend. one of the games biggest stars now saying fans need more protection. phillip mena has the story. >> that one is

stretcher in a neck brace. >> they'll take her out of the ballpark now. >> reporter: now players, including superstar justin verlander, saying enough is enough, urging baseball officials to take action. >> seems like something happens once a game where, a ball just misses a fan. it's something that needs to be addressed. immediately. >> this is a broken bat grounder. >> reporter: at fenway park in june, tanya carpenter, severely injured after a broken bat flew into the stands. one month later, stephanie wapenski hit with a foul ball. >> the fact i got hit between the eyes, kind of reflects that i couldn't have been looking more flushly at what was going on. all this, as an oakland a's fan filed suit against major league baseball, demanding the league extend protecting netting to the foul lines. the commissioner not sure the protections would be a huge hit with everyone. >> we have fans that express strong preferences for seats that are close to the field and do not have

height? eye color? strength? musical aptitude? sexual orientation? >> reporter: for some parents who already have a child, gender selection is the way to guarantee a baby of the opposite sex. >> since it's there. and we have the option to do that, we would very much like a girl. >> reporter: this couple, who didn't want us to use their names, says when they learned about the option of gender selection decided to choose a daughter. >> i come from a family of all boys. we had a son. and i really said i would like to have a daughter. >> and we got two. >> reporter: now they have twin daughters. in addition to their older son. they haven't ruled out using gender selection again. >> are you happy with our decision? >> definitely not. i tell you what -- listen. wonderful. couldn't be happier. >> and here, dr. jennifer ashton. let's talk about how doctors go about determining gender. what is the medical science? >> there's two methods. the first one is known as sperm sorting. basically, using a high-tech method called flow sperm carrying a y chromosome are separated from those carrying an x chromosome. the second is pgd, or preimplantation genetic diagnosis. after the embryo is fertilized. as it goes through the cell division stage, it gets to about the five-day stage. then think of it like a very, very delicate biopsy. or a superearly amniocentesis. part of the cell is removed and tested. >> obviously, people do this for gender selection. others do it for medical reasons. >> right. and that's really how it started, amy. to look for certain medical disorders. things genetically passed on. from generation to generation. like cystic fibrosis. sickle cell disease. hemophilia. there are over 100 diseases that can be tested for. and it also can be used in a parent has an existing sick child to look for an exact match for a stem cell transplant. obviously, this is still tremendously controversial, especially around the world. >> can you break down the pros and cons? >> this is where the medical becomes ethical and legal. when you talk about the ethical principles here, the things that are for this, or for non- medical gender selection, the principles of patient autonomy and reproductive liberty, those are very individual. and that's up to that patient or that couple. the things on the opposing side, against this, you're talking about gender discrimination. we have seen that in china and india, where they want a boy child. or inappropriate use of medical resources. we have to remember, there are risks involved. when you do it for a nonmedical reason, you have to be okay can getting bad outcomes. >> as a doctor, your thoughts? >> as a doctor and a mom, my motto is stay in your lane. for nonmedical reasons, be surprised. take what nature gives you. >> dr. jen, we appreciate it. and dr. ashton will be taking your questions on twitter. tweet her at drjashton. i'm sure you'll get quite a few. >> yep. >> robin, send it over to you. >> stay in your lane. got it. >> good advice. next up, the health trend getting a lot of attention right now. alkaline water. proponents say drinking it does the body good. does the science back up the claims?
