>> that's all for this edition of "dateline extra." i'm tamron hall. thanks for watching. danger. >> sharks flashing back and forth. >> adrenaline. >> it's magnificent. it's crazy. adventure. >> there are a lot of things that can go wrong. >> it's what drives theseida da devils. they fly at high speed and challenge gravity. they dive to get close to sharks. >> i'm just looking out the jaws of death. >> that's only the beginning. >> next thing you know, he knocks the regulator out of my mouth. i have to get out of the cage or

drown and the shark's going to bite me. >> they're thrill seekers. they have no fear. >> caught on camera, risk. >> they live on the edge. they're addicted to adrenaline. they're dare devils and they're constantly pushing the limits to go faster and farther and higher than anyone else. but sometimes the rush is replaced by a jolt of pure terror. faster than a speeding bullet. it's a bird. it's a plane. no, it's a man in a wing suit? that's right. and it doesn't get much more daring than this. >> three, two, one.

>> many of us have had that dream about flying when you're small. flying your wing suit in the mountains is that feeling. >> wing suit jumpers reach speeds up to 150 miles per hour. >> it's life medicine for me, and those two, three, four first secon seconds. they are just extraordinary. >> but with big reward comes big risk. >> it's magnificent. it's crazy. >> for norwegian wing suit flier hans lange, this day starts out like any other. >> it was a beautiful day. blue skies, no winds. perfect for wind suit flying in the mountains. >> after a long hike up a mountain in northwestern norway, hahns and a few friends find the spot they're looking for, a 2 foot by 1 foot ledge perched

more than 5,000 feet above the ground. for hans, there's only one way down. >> when i jump off, i gain speed. you go pretty vertical the first four, five seconds. then you flatten out when you get speed in the suit. >> so far, hans' flight is going as planned. >> after 10, 12 seconds of freefall, i say, this is nice. i have a nice path. i made a left curve, a slight one, to lose some height and gain some speed. so i made a sharp right turn, going pretty close there. and then make a left turn into the neighboring valley. i was like, this was marvelous. and my hair was like -- and my neck, it was awesome. >> but now, streaking along the mountainside at about 110 miles per hour, caught on his helmet camera, a great jump turns disastrous in an instant.

he's getting too close to the mountain, so he deploys his parachute. >> when i open my parachute, i'm very aware that i have a wall to the right-hand side. >> if he crashes into the mountain, it could mean death, so he fights with everything he has to turn his parachute away from the menacing wall. >> instantly, when i saw that i'm going for it, it's going to be a fight for life and death. i just put all my energy on hitting the wall. after the impact, you are only working. working, working, working to survive. >> hans uses his legs to kick himself away from the rock, and much to his surprise, it works. >> so i was like, wow. i'm flying out again. you know.

i got a second chance. >> he doesn't immediately realize the lines attached to his parachute are twisted, and he begins to fall, straight down. >> bam. i felt immediately that bang took my leg. >> his collision with the unforgiving rock breaks his leg. >> i just felt an instantaneous pain. and i see the bushes. i'm into the bushes, luckily. >> hans sounds worse than his injuries actually are. the bushes provide a nice soft landing spot. >> that had been pure rocks or a shelf or something, i could have died. people have died in that situation before me. >> he's so happy to be alive, but as the pain of his broken leg sets in, so does a whole range of emotions.

>> i was so angry and so lucky in one moment. i was angry because it was a lack of concentration. i don't think i have said so many swearing words in a row. >> hans' anger is short-lived. a rescue helicopter is on the way, and as he lays in his makeshift bed of bushes, hetries to make some sense of what happened to him. at first, hans is having what he thinks is a great flight. but as he carves his way around the mountain, seemingly flying, it's on this turn that he says he makes an almost deadly mistake. >> the major error was i was flying too closto the mountain. >> so close that when he tries to connect the mistake by deploying his parachute, he doesn't have time to turn around, away from the rock face and into open space. >> i feel trapped.

and i was very afraid of doing a turn, doing a turn, you lose lots of altitude. >> so he sees only one choice. >> when i understood that there was only one way and that was into the mountain, i was scared. you just have to try to avoid what might kill you. it goes very fast. >> and luckily, he does survive what could have been a deadly fall. >> the helicopter is coming right now to get me. >> the chopper arrives and hoists hans to safety. he's flown to a hospital where he's treated for his broken leg and given stitches for a few cuts, but amazingly, has no life-threatening injuries. >> lesson learned. don't hit the mountain. coming up -- >> the sharks just flashing back and forth. >> a man fights for his life under water. >> next thing you know, he

knocks my regulator out of my mouth. >> no air, a shark on the attack. >> and later -- >> the first steps are some of the worst. the start is the most difficult. at planters we know how to throw a remarkable holiday party. just serve classy snacks and be a gracious host, no matter who shows up.

to some sharks, but his story is a reminder, be careful what you wish for. >> the sharks just flashing back and forth. i've got my hands on his nose and his mouth. i'm looking into his mouth. >> jerry loman is fighting for his life. as this huge great white shark flashes its razor sharp teeth and rams through the very cage that's supposed to protect jerry. >> i mean, he's shaking literally the whole cage, and surprised it just doesn't break apart. >> terrified and trapped, his ordeal is only just beginning. it's a lot more than this 30-year-old banker from the midwest bargained for when he signed up for the shark dive off the coast of south africa. a self-described adrenaline junky, he knew it would be dangerous, and it started as the thrilling experience he hoped for. >> you couldn't have scripted it better. this once in a lifetime experience where these huge, huge creatures get so close to you. >> close, but this close?

>> you know, stuff's going to happen, but you have to live your life. you only have one life. >> and jerry decides he needs to live it to the fullest. as vice president at a large bank, he works long hours, nights, weekends, and hasn't ever really taken a vacation. when he sees an ad in the paper for a trip to south africa, he makes a spontaneous decision and packs his bag. >> i was going to pull out all the stops and kind of the piece deresistance was this cage diving, shark diving. >> just a couple months after seeing the ad in the paper, jerry finds himself in one of the diving capitals of the world, 30 miles out of cape town at the southern most tip of south africa, staring at a shark cage. >> you're shaking at your head looking, like wow, that thing is so small. if one of these sharks wanted to get in it, there's no stopping

it. >> and as jerry sizes up the shark cage, he notices an even bigger concern. >> you kind of remember noting that it seemed like there was a big hole. big holes around the side there. they had mentioned that they had removed a bar so a camera crew could swim in and out of it and they hadn't put it back. >> jerry thinks that hole looks big enough for a shark to get through, but the captain assures him he'll be safe, so he nods cautiously and boards the boat. after all, he didn't come halfway around the world to miss out on seeing great white sharks, and when out at sea he finally gets a look at one of these massive creatures, he understands why the captain isn't concerned about the little gap between bars. >> this thing looked like a subrumean. it was huge. >> jerry loves it. he's hooked. >> really inquisitive, swimming up on the bottom, the sides, getting close. you could almost play with them. >> but jerry never imagined a

shark could get this close. >> then bam, he hits this cage. just spot on. right in the opening that they had the bar removed. all of a sudden, you so this huge head with just teeth inching its way closer and closer. >> any diver's worst nightmare, jerry and another tourist are forced to the bottom of the cage to avoid the now thrashing shark. >> i'm looking like this can't be happening. then i just can't die. >> but the shark is forcing his way further and further into the cage. >> it was a fuew inches away. i remember looking into his mouth. i have my hands on his nose. >> jerry is frantically searching for a way out. >> i wasn't going to be able to swim up to the top because he was moving around too much and more than likely, he would bite a leg or arm. >> the situation is dire and almost unbelievably, it's about to get worse. >> next thing you know, he knocks my regulator out of my mouth. >> with no air supply, it's do or die.

>> i realize i have to get out of the cage or i'm going to drown or the shark is going to bite me. >> he has to think quickly. >> okay, he came in the side, i'm going to go out the side. i'm trying to throw him off, throw him off, then he manages to turn his head, and realized there was an opening. >> the other diver sees what jerry does and knows if he stays where he is, it could mean death. so miraculously, she shoots out of the other side of the cage. they're both out, thrilled to be alive, but the danger is far from over. coming up -- >> jerry loman is out of the cage but he's not out of the water yet. >> i had 10, 12 kilos of weight on me. i start falling. >> no air, shark infested waters. a dramatic fight for survival. and later -- >> balancing on the brink. a high-wire walker steps into danger. when "caught on camera" continues. go, go!

the midwest, was hoping for the trip of a lifetime when he booked his six-week vacation to south africa. but when he finds himself underwater without oxygen fighting fiercely with a five-ton great white shark, he knows he's one head thrash away from death, and then suddenly, he sees an opening, and somehow,

he manages to escape the wrath of the great white. but as soon as he finds himself in open water, he realizes he's not out of danger yet. his lungs are burning for air, and he can see the surface, but he just can't get there. >> i start falling. forgetting actually that i had 10, 12 kilooffs weight on me because it was a big strong current there and i needed to be weighted down. >> with 10 to 12 kilos of 25 pounds shoving him underwater, he manages to grab the bars of the cage. >> i realize i need to get out of the water, a, i don't have a regulator in my mouth, and b, there are other sharks swimming around. >> he climbs up the cage, emerges from the water, and finally, the air his body is craving. >> they throw me in the boot. i remember laying face down, and thinking did that really happen? >> he sees the other diver who was in the cage with him, also with his limbs intact. >> he says, man, you saved my

life. i was just going to stay there. you actually made a decision and got of the side, and it worked for you, so i thought i would try it. >> they're both safe on the boat now, but realize the shark they escaped is now the one fighting for its life. >> great whites have to swim constantly to get the oxygen thou the water to survive. if he stays in the cage, he's going to die. >> despite his ordeal, he doesn't want to see the shark die, so the group works to tip the free and free it, but when he comes to land, jerry can't seem to free himself from the memory of the close encounter. >> i had nightmares for four to six months, waking up. you put your arm somewhere, he would bite your arm off. >> finally, he's at peace with what happened that day. >> i have come full circle, before, i was more in the corporate world, and now actually for a living i'm a dive instructor. >> a dive instructor? that's right.

a perhaps the most surprising part of this whole story is jerry loman mau runs his own dive company out of phuket, thailand. >> i'm surprised i'm a dive instructor for a living. we see sharks on a daily basis. i hadon't have residual effects but it was a scary, traumatic event. christian is balancing on a narrow cord more than 3,000 feet above a noregen fiord. he's attempting the highest slack wine walk when sudden ly - it's august 3rd, 2006, christian is atop a mountain in southwest norway. he's strung the nylon cord himself, testing each screw to make sure it's screcurely fasted and then edging along the wire, checking it inch by inch. his only protection if he falls

during the event is a safety harness attached to the line. good the cord or screws break, christian will plunge to his death. >> translator: there are a lot of things that can go wrong. for example, you could have something sharp in your pocket that could cut the line. >> once krishz has gone through his safety check, he starts psyching himself up for the attempt. music gets him in the zone. it's hard to believe anyone could relax perched so high above the rocky cliffs, but with his feet tangling over the edge of the canyon like he's just sitting at the kitchen table, christian finds peace. he's ready. he edges along the rope to the other side of the ravine. christian climbs onto the line and struggles to find his balance. he's tried and failed to do this same slack line walk before. so he knows how difficult it will be.

>> translator: the first steps are some of the worse. the start is the most difficult. >> tentatively, he takes a few steps. he tumbles, instinctively clinging to the rope for safety. it's a scary reminder of how easily this can go wrong. seemingly unshaken, christian prepares to start again. unlike a tightrope, the slack line is loose. it bounces and swings as christian tries to balance. the line is flat, but it's only one-inch thick. christian is 3,280 feet in the air. that's nearly three times the height of the empire state building. slowly, cautiously, breathing

deeply, christian places one foot in front of the other, bridging the gulf step by step. as he reaches the halfway point of the 39-foot crossing, he starts singing to himself. a tiny voice in the vast canyon. seconds later -- he's made it. immediately after the stunt, krishz tries to explain why he took on the challenge. >> translator: we create contrast in our lives. so that for things to be really great, we must also experience hell. standing on that line is hell. it's good to come home and sit on the sofa and relax. >> if you have a video you would like to send us, logon to our website.
