earlier this year, we showed you for the first time drone video of what turned out to be the largest ballistic missile attack ever against americans, and we talked to the troops who were there on the night the u.s. and iran went to the brink. >> alan johnson: hey, buddy. if you're seeing this video, some bad things happened to dad last night. so, i need you to be strong, okay, for mom. and just always know in your heart that i love you, okay? bye, buddy. >> martin: a few hours after army major alan johnson recorded that message to his son, iranian batiiles ban rai wn on sad airbase in iraq where 2,000 u.s. troops were based. as a drone recorded the attack, americans caught in the crosshairs could do nothing but run or duck and cover. ( explosion )

>> holy ( bleep )! >> martin: each missile carried a warhead weighing more than 1,000 pounds. >> stay right here, bro, don't move. >> johnson: well, words can't even describe the amount of energy that is released by these-- these missiles. >> martin: johnson was taking cover in a bunker designed to protect troops against much smaller warheads, weighing only 60 pounds. >> johnson: knocked the wind out of me, followed by the most putrid-tasting, ammonia-tasting dust that swept through the bunker, coated your teeth. >> martin: after the blast wave and debris came the flames. >> johnson: the fire was just rolling over the bunkers, you know, like 70 feet in the air. >> martin: johnson's bunker provided no protection from that. >> johnson: we're going to burn to death. we start heading down 135 meters, make it about a third of the way there, the "big voice," we call it, clicks in, "incoming, incoming, take cover, take cover, take cover." i've got another football field

to run. i don't know when this next missile's going to hit. >> martin: can you hear the incoming? >> johnson: like a freight train going by you. >> martin: johnson wasn't the only one frantically searching for cover. >> johnson: it's six people running for their lives to get to this next bunker. we get to the bunker and realize there's roughly 40 people trying to stuff themselves into this bunker that's made for about ten folks. and i grabbed the guy in front of me and i'm just like, "you got to get in the bunker!" and just, like-- like, shoved everybody in there. >> martin: but, when you're running between bunkers, it's just a matter of, what, luck? >> johnson: luck. the only thing i can actually come up with is that hand of god protected us. because, really, nobody should have lived through this. >> frank mckenzie: things are happening that could take us to war if we don't make the correct move here. >> martin: marine general frank mckenzie, commander of u.s. forces in the middle east, monitored the attack from his

headquarters at tampa, florida, ducking into this small room off his main operations center where he could talk directly to the only two people above him in the chain of command. >> mckenzie: they bring in the secretary of defense, and then a little bit later, they brought in the president to this conversation. we're listening to the reports of the missiles flying. >> martin: you ever been on one like this? >> mckenzie: i've never been on one like this where real missiles being fired at our forces and where i thought the risks were so high. >> martin: the iranian attack on al asad was in retaliation for a stunning u.s. operation president trump ordered six nights earlier: a drone strike which killed iran's most powerful general, quasem soleimani. >> mckenzie: the blood of many americans is on the hands of quasem soleimani. he was as close to an indispensable man as you could find inside iran. where he went, violence and death followed. >> martin: during the american occupation of iraq, soleimani had orchestrated attacks which killed more than 600 u.s. troops and, according to mckenzie, he was planning to do it again.

>> mckenzie: we saw intelligence reports where quasem soleimani was moving various attack streams forward against our forces in iraq, against our embassy, and against other bases there. >> martin: were they imminent? >> mckenzie: perhaps in hours, perhaps in days. probably not weeks. >> martin: until then, the u.s. had shied away from going after soleimani for fear killing such a high-ranking government official would only provoke more iranian attacks. >> mckenzie: i never take killing anyone as-- as an easy decision, but i think the risk of not acting in this case outweighed the risks of acting, so, yes, i was good with the decision. >> martin: on january 3 of last year, an airport security camera recorded soleimani's arrival in baghdad on a commercial flight from damascus. mckenzie was watching from a different angle. you have the drones overhead. do you see him? >> mckenzie: yes. >> martin: get off the airplane? >> mckenzie: yes, yes. >> martin: as soleimani's entourage pulled away from the plane, mckenzie gave the kill order to the commander controlling the drones. >> mckenzie: and then i said, "take your shot when you got

it." >> martin: missiles slammed into both vehicles simultaneously. >> mckenzie: there's no back- slapping. there's no cheering. because now i have to prepare to deal with the consequences of the action. >> martin: general mckenzie was sure iran would retaliate, but he didn't know. and neither, for a while, did the iranians. >> mckenzie: i believe they went into a period of disorganization because they had lost the officer who really spoke up and shaped everything up and told them what they were going to do. >> martin: so it was kind of an ominous silence. >> mckenzie: it was a very ominous silence. >> martin: and what was the first sign that iran might really be thinking of a ballistic missile attack? >> mckenzie: they began to move their ballistic missiles. >> martin: the attack was just hours away when major alan johnson got the word iran's most powerful weapons were aiming for al asad. >> johnson: my intelligence officer pulled me aside basically said, "sir, i've got some bad news for you." "what's up?"

"we have information that iran is fueling 27 medium-range ballistic missiles, and their intention is to level this base and we may not survive." >> tim garland: this is a completely different threat. >> martin: lieutenant colonel tim garland commanded an army battalion at al asad, a sprawling airbase about 120 miles west of baghdad where the u.s. operated scores of helicopters, drones and other aircraft. did the base have any defense against ballistic missiles? >> garland: no, sir. it was such an unprecedented threat, i don't think it was ever calculated, so the capability to prevent a ballistic missile attack, it-- it wasn't there. >> martin: did you have a plan for what to do? >> garland: we came up with a plan. >> staci coleman: the only real fense against a ballistic missile attack is to get out of harm's way. >> martin: air force lieutenant colonel staci coleman and the rest of al asad scrambled to evacuate more than 50 aircraft

and 1,000 troops before the missiles hit, but the base still had to be manned. >> coleman: we still needed to be able to do our mission. so the first decision was to split our team by combat capability. >> martin: what did you think was going to happen to the people you were telling to stay? >> coleman: the honest truth is, i didn't think that we were going to survive. >> martin: the best shelter was air raid bunkers built during the rule of saddam hussein, but there weren't enough of them. >> garland: and i just remember a very heavy sinking feeling setting in. it was like, man, we-- we are not going to come up with a bunker plan that's going to be adequate for the number of people that we're talking about. >> martin: so, garland sent most of his soldiers out into the desert, where they watched the attack from a safe distance. >> garland: there was a lot of people who didn't want to leave. they didn't want to be that guy that was going to relative safety. >> martin: a lot of people might have trouble understanding what

you just said. tell me why a soldier wouldn't want to go to a safe place. >> garland: they want to carry the burden. they want to share in the danger. >> martin: from his headquarters in tampa, general frank mckenzie had tried to time the evacuation just right. >> mckenzie: if you go too early, you risk the problem that the enemy will see what you have done and adjust his plans. >> martin: the iranians monitored al asad by purchasing photos like these, taken by commercial satellites. mckenzie waited until after iran had downloaded its last picture for the day. so, the last time the iranians took a look with their commercially-acquired spy photos, what would they have seen? >> mckenzie: they would have seen airplanes on the ground and people working. >> martin: so when they launched those missiles, they thought that was going to be a full flight line. >> mckenzie: i think they expected to destroy a number of u.s. aircraft and to kill a number of u.s. service members.

>> martin: a clock, stopped at 1:34 a.m. when it was knocked off the wall, recorded the moment the first missile landed. >> john haines: it's like the sun rising-instantaneous. that's how bright it was. >> martin: air force master sergeant john haines and his security team were outside their armored patrol vehicle when the first missiles struck. >> haines: and across the radio we heard, "incoming, incoming, incoming." >> martin: what do you do? >> haines: i just threw the phone down and ran to my vehicle. and once that impact happened, the back pressure blew our doors closed and then you just see cloud of dirt, fire. >> coleman: they call it a "shock wave," and you kind of feel that-- that wave, almost internally. like, it's almost as if you, your organs are, you know, kind of wavering around inside. >> martin: sergeant kimo keltz was outside the bunkers, manning a guard post in case the missile barrage was followed by a ground assault. >> kimo keltz: we got down and we protected our-- our vital organs, our heads. and we waited. >> martin: did it blow you around? >> keltz: in one of the closest

ones that had hit directly near us, had actually lifted my body about two inches t >> martin: iran fired a total of 16 missiles from three locations. five missed. 11 landed at al asad. this was an attack like no other. >> mckenzie: it was an attack certainly like nothing i've ever seen or experienced. >> martin: what have you learned so far? >> mckenzie: their missiles are accurate. >> martin: did that surprise you? >> mckenzie: we knew it, but, to see it? they fired those missiles to significant range, and they hit pretty much where they wanted to hit. >> martin: from first launch to last impact was 80 minutes. somehow, no one was killed. when the sun came up, the survivors surveyed the damage. >> holy ( bleep )! >> garland: shells of a building-- you know, skeletal frames left with nothing else. craters about a room-size deep into the ground. concrete barriers blown across a

field or a street. >> haines: it looked like a scene from a movie where everything is destroyed around you, but yet, no one was killed. >> coleman: i still have no idea, understanding, other than, you know, god being on our side, that no one was seriously injured and there were no-- you know, no-- no fatalities. >> martin: the news traveled fast up the chain of command, and president trump tweeted, "all is well." that turned out to be premature. >> johnson: there are people throwing up. everybody had headaches. >> keltz: i had a concussion for two weeks. >> martin: what'd it feel like? >> keltz: someone hitting me over the head with a hammer, over and over and over. >> johnson: finally, you know, hours later, we realized, "we have a mass casualty event here of traumatic brain injury." >> martin: military doctors diagnosed more than 100 cases of traumatic brain injury. major alan johnson and 28 other soldiers received purple hearts.

do you have any lingering effects today? >> johnson: headaches every day, horrible tinnitus, or ringing in the ears. p.t.s.d.-- you know, i'll be willing to admit that. i still have nightmares. >> martin: but the nightmare of war with iran had been averted. >> mckenzie: had americans been killed, it would have been very different. >> martin: have you ever done an estimate on, if you hadn't evacuated, the damage that would have been done? >> mckenzie: sir, i think we might have lost 20 or 30 airplanes, and we might have lost 100 to 150 u.s. personnel. >> martin: you had a plan to retaliate if they killed americans. >> mckenzie: david, we had a plan to retaliate if americans had died. >> martin: iran was on alert for a possible u.s. strike, and hours later, shot down a ukrainian airliner, thinking it was an american bomber. 176 entirely innocent people died.

>> anderson cooper: boston dynamics is a cutting-edge robotics company that's spent decades behind closed doors making robots that move in ways we've only seen in science fiction films. they occasionally release videos on youtube of their life-like machines spinning, somersaulting, or sprinting, which are greeted with fascination and fear. as we first told you this past spring, we've been trying-- without any luck-- to get into boston dynamics' workshop for years. and in march, they finally agreed to let us in. after working out strict covid protocols, wnt to massachusetts to see how they make robots do the unimaginable.

from the outside, boston dynamics headquarters looks pretty normal. inside, however it's anything but. if willy wonka made robots, his workshop might look something like this. there are robots in corridors, offices and kennels. they trot and dance and whirl, and the 200 or so human roboticists who build and often break them barely bat an eye. that is atlas, the most human- looking robot they've ever made. it's nearly five feet tall, 175 pounds, and is programmed to run, leap and spin like an automated acrobat. wow. marc raibert, the founder and chairman of boston dynamics, doesn't like to play favorites, but definitely has a soft spot for atlas. >> marc raibert: so, here's a little bit of a jump. >> cooper: i mean, that's incredible.

( laughs ) atlas isn't doing all this on its own; technician bryan hollingsworth is steering it with this remote control. but the robot's software allows it to make other key decisions autonomously. >> raibert: so, really, the robot is... >> cooper: that's incredible. >> raibert: ...you know, doing all its own balance, all its own control. bryan's just steering it, telling it what speed and direction. its computers are adjusting how the legs are placed and what forces it's applying in order to keep it balanced. >> cooper: atlas balances with the help of sensors, as well as a gyroscope, and three onboard computers. it was definitely built to be pushed around. >> raibert: good. push it a little bit more. it's just trying to keep its balance, just like you will, if i push you. and you can push it in any direction. you can push it from the side. >> cooper: making machines that can stay upright on their own and move through the world with the ease of an animal or human has been an obsession of marc raiberts' for 40 years. the space of time you've been working in is nothing compared

to the time it's taken for animals and humans to develop. >> raibert: some people look at me and say, "oh, raibert, you've been stuck on this problem for 40 years." animals are amazingly good, and people, at-- at what they do. you know, we're so agile. we're so versatile. we really haven't achieved what humans can do yet, but i think-- i think we can. >> cooper: raibert isn't making it easy for himself. he's given most of his robots legs. why focus on-- on legs? i would think wheels would be easier. >> raibert: yeah, wheels and tracks are great, if you have a prepared surface like a road, or even a dirt road. but people and animals can go anywhere on earth using their legs. and so, that-- you know, that was the inspiration. >> ready? one, two... >> cooper: some of the first contraptions he built in the early 1980s bounced around on what looked like pogo sticks. they appeared in this documentary when raibert was a pioneering professor of robotics and computer science at carnegie mellon. he founded boston dynamics in 1992, and, with c.e.o. robert

playter, has been working for decades to perfect how robots move. they developed this robot, called big dog, for the military, as well as this larger pack mule that could carry 400 pounds on its back. experimenting with speed, they got this cheetah-like robot to run nearly 30 miles an hour. none of these made it out of the prototype phase, but they did lead to this. it's called spot. boston dynamics made it, not knowing exactly how it would be used, but the inspiration for it isn't hard to figure out. >> hannah rossi: so, spot is a omni-directional robot. so, it can go forwards and backwards. >> cooper: this is crazy. ( laughs ) >> rob playter: this is the real benefit of legs. legs give you that capability. >> cooper: that's robert playter, the c.e.o.; and hannah rossi, a technician who works on spot. >> rossi: i'm not doing anything special to let it walk over those rocks. there you go. >> cooper: the controls are easier to use than you might

expect. does it have to come in, straight on? >> rossi: you don't have to be perfect about it. drive it close to wherever you want to go, and the robot will do the rest. >> cooper: wow. in some ways, it's like driving a very sophisticated remote control car. what makes it er >> playter: spot is really smart about its own locomotion. it deals with all the details about how to place my feet, what gait to use, how to manage my body so that all you have to tell it is the direction they go to. >> cooper: and, in some cases, you don't even have to do that. when signaled, spot can take itself off its charging station and go for a walk on its own as long as it's pre-programmed with the route. it uses five 3d cameras to map its surroundings and avoid obstacles. i mean, it is like something... atlas has a similar technology. while we were talking in front of atlas, this is how it saw us. >> raibert: this is inside

atlas' brain, and it shows its perception system. so, what looks like a flashlight is really the data that's coming back from its cameras. and it-- you see the white-- rectangles? that means it's identifying a place that it could step. and then, once it identifies it, it attaches those footsteps to it, and it says, "okay, i'm going to try and step there." and then, it adjusts its mechanics so that it actually hits those places when it's running. >> cooper: all of that happens in a matter of milliseconds. >> raibert: and so, it's going to use that vision to adjust itself as it goes running over these blocks. >> cooper: atlas cost tens of millions of dollars to develop, but it's not for sale. it's used purely for research and development. but spot is on the market. around 500 are out in the world. they sell for about $75,000 apiece. accessories cost extra. some spots work at utility companies, using mounted cameras to check on equipment. others monitor construction sites, and several police

departments are trying them out to assist with investigations. let's talk about the-- the fear factor. when you post a video of atlas or spot doing something, a ton of people are amazed by it and think it's great, and there's a lot of people who think this is terrifying. >> playter: the rogue robot story is a powerful story, and it's been told for 100 years. but it's fiction. robots don't have agency. they don't make up their own minds about what their tasks are. they operate within a narrow bound of their programming. >> cooper: it is easy to project human qualities onto these machines. >> playter: i think people do attribute to our robots much more than they should because, you know, they haven't seen machines move like this before. and so, they-- they want to project intelligence and emotion onto that in ways that are fiction. >> cooper: in other words, these robots still have a long way to go.

i mean, it's not c-3po. it-- it's not a thinking... >> raibert: yeah. so, let me tell you... >> cooper: okay. >> raibert: ...about that. there's a cognitive intelligence and an athletic intelligence. you know, cognitive intelligence is making plans, making decisions, reasoning, and things like that. >> cooper: it's not doing that? >> raibert: it's mostly doing athletic intelligence... >> cooper: okay. >> raibert: ...which is managing its body, its posture, its energetics. if you told it to travel in a circle in the room, it can go through the sequence of steps. but if you ask it to go find me a soda, it's-- it's not doing anything like that. >> oh, no! >> cooper: just picking an item off the floor can sometimes be a struggle for spot. enabling it to open a door has taken years of programming and practice, and a human has to tell it where the hinges are. >> kevin blankspoor: each time we add some new capability and we feel like we've got it to a decent point, that's when you push it to failure, to figure out, you know, how good of a job you've really done.

>> cooper: kevin blankespoor is one of the lead engineers here, but, at times, he prefers a very low-tech approach to testing robots. you're pretty tough on robots. >> blankespoor: we think of that as-- as just another way to push them out of the comfort zone. >> cooper: failure is a big part of the process. when trying something new, robots, like humans, don't get it right every time. there might be dozens of crashes for every one success. how often do you break a robot? ( laughs ) >> raibert: we break them all the time. i mean, it's part of our culture. we have a motto: "build it, break it, fix it." >> cooper: to do that, boston dynamics has recruited roboticists with diverse backgrounds. there's plenty of ph.d's, but also bike builders and racecar mechanics. bill washburn is part of that pit crew. they all look pretty dinged up. >> bill washburn: yeah. >> cooper: how often do these need to get repaired? >> washburn: the biggest kind of failures for me are, like, the

bottom part of the robot breaks off of the top part of the robot. ( chuckle ) and it's like... >> cooper: that seems like a big, big failure. ( chuckle ) >> washburn: and the hydraulic hoses are the only thing holding it together. >> cooper: recently, raibert and his team decided to push their robots in a way they never had before. >> raibert: we spent at least six months, maybe eight, just preparing for what we were going to do. and then, we started to get the technical teams working on the behavior. >> cooper: the behavior was dancing. ♪ do you love me? ♪ all their robots got in on the act. ♪ ♪ ♪ ♪ ♪ ♪ the movements were cutting edge, but the music and the "mashed potato" were definitely old- school. ♪ i can mashed potato ♪ there are some people who see that and say, "that can't be real." >> raibert: nothing's more gratifying than hearing that. ♪ ♪ ♪ ♪ ♪ ♪ >> cooper: what's the point in proving that the robot can do the "mashed potato?" >> raibert: this process of, you

know, doing new things with the robots, lets you generate new tools, new approaches, new understanding of the problem. that takes you forward, but, man, isn't it just fun? >> cooper: but, i mean, it's-- it costs a lot of money. it took 18 months of your time. >> raibert: i think it was worth it. ( laughter ) >> cooper: whether it'll be worth it to boston dynamics' new owners is less clear. >> raibert: a lot of detail. >> cooper: the south korean car maker, hyundai, has purchased a majority stake for $1 billion. it is boston dynamics' third owner in eight years. there's pressure to turn their research into revenue, and boston dynamics hopes this new robot will help. it's called stretch, and it's due to go on sale next year. this was the first time they'd shown it publicly. >> blankespoor: warehouses is really the next frontier for robotics. >> cooper: stretch may not be that exciting to look at, but it's built with a definite purpose in mind. it's got a seven-foot arm, and they say it can move 800 boxes

an hour in a warehouse, and work for up to 16 hours without a break. unlike many industrial robots that sit in one place, stretch is designed to move around. >> blankespoor: you can drive it around with a joystick, and, at times, that's the easiest way to get it set up. but once it's ready to go in a truck and unload it, you hit go, and from there on it's autonomous. and it'll keep finding boxes and l it all the way through. >> playter: this generation of robots is going to be different. they're going to work amongst us. they're going to work next to us in ways where we help them but they also take some of the burden from us. >> cooper: the more robots are integrated into the workforce, the more jobs would be taken away. >> playter: at the same time, you're creating a new industry. we envision a job we-- we-- we like to call the robot wrangler. he'll launch and manage five to ten robots at a time and sort of keep them all working. >> cooper: is there a robot you've always dreamt of making that you haven't been able to d?

( laughs ) >> raibert: a car with an active suspension, essentially legs like-- like a roller-skating robot. and a robot like that, you know, could go anywhere on earth. that's one thing that maybe we'll do at some point. but, you know, really, the sky's the limit. there's-- there's all kinds of things we can and will do. ♪ ♪ ♪ ♪ ♪ ♪ >> cooper: as with so many things boston dynamics does, it's hard to imagine how that would work. but then again, who'd have thought a bunch of metal machines would one day show us all how to do the "mashed potato." ♪ watch me now! ♪ ( ticking ) >> cbs sports hq presented by progressive. world golfship. in memphis, tennessee. abe ram ancer was the winner over japan's hideki matsuyama, and his first career victory. news was legendary from

>> bill whitaker: when lewis and clark first encountered grizzly bears, there may have been 100,000 of them in the american west, from what is now canada all the way down to mexico. grizzlies are among the most fearsome predators on the planet, so for the next 150 years, they were systematically exterminated by settlers, ranchers, and farmers who saw them as a threat to their lives and livelihoods. by the 1960s, there were just a few hundred left in the lower 48 states. in 1975, grizzly bears were among the first animals to be protected under the endangered species act. and as we reported last year, what's happened since, especially in the state of montana, is a story both of conservation and conflict. ever been face-to-face with a grizzly? neither had we. >> erik wenum: ready?

>> whitaker: yeah. in the swan mountains of northwestern montana, we're carrying bear spray and following state bear specialist erik wenum and his colleague milan vinks deep into the woods. >> wenum: ( whistles ) hey! >> whitaker: wenum's checking one of several traps- called snares- >> wenum: oh, there's a bear. >> whitaker: --that he has baited with beaver meat. >> wenum: grizzly bear. >> whitaker: hear that? >> wenum: the closer we get, the more agitated she's going to become, so we'll kind of be quiet-- get a good weight assessment on her, and then we'll just drift right back out, okay? >> whitaker: i'm with you. >> wenum: all right. you're okay. ( growling ) you're all right, you're okay, you're okay. ( growling ) you're all right. you're all right. >> whitaker: after the wire

snare around its wrist stops the first charge at wenum, the grizzly makes another effort to get at our cameraman, don lee. ( growling ) >> wenum: yeah, you're all right. all right, we'll drift out. >> whitaker: you have an estimate of how big that bear is? how much do you think she weighs? >> wenum: i think it's right around 300 pounds. >> whitaker: that's mid-sized for a grizzly. they can weigh as much as 1,000 pounds and stand nine feet tall on their hind legs. >> wenum: we're going to mix a little bit of medetomidine. >> whitaker: wenum and vinks mix a cocktail of veterinary sedatives and load them into a dart gun. >> whitaker: you have the dart, i have the bear spray, we're ready. >> wenum: there you go, we are set. >> whitaker: vinks carries a shotgun loaded with lethal ammunition, just in case. wenum insists that neither the tranquilizer nor the snare do

any lasting harm, and that he needs both as part of a project to attach radio collars to grizzlies and track their population's recovery. >> hilary cooley: to me, having a grizzly bear population means that the ecosystem is intact. >> whitaker: hilary cooley is the wildlife biologist in charge of grizzly bear recovery for the u.s. fish and wildlife service. >> cooley: grizzly bears were listed in 1975 as a threatened species in the lower 48 states. >> whitaker: thought their survival was in jeopardy? >> cooley: yeah. their range had been reduced by about 98%. >> whitaker: two places grizzlies hadn't been wiped out were glacier and yellowstone national parks, where a few hundred were protected from eradication. so, starting 45 years ago, the recovery effort focused on millions of acres around those two parks. >> cooley: they've probably more than tripled their numbers, and their range now is more than double what it was at the time

of listing. >> whitaker: since listed as an endangered species back in 1975, the grizzly bear population in this region has made a remarkable comeback-- a true success story. but at the same time, another population has also been growing around here-- the human population- with houses and subdivisions built right next to the wilderness. and that's often where the trouble starts. montana's human population has grown by 250,000 since grizzlies were protected in 1975. most of those people live on valley floors or in foothills not far from bear country. >> bryce andrews: when you can look at the telemetry from their collars, you realize that at night, this valley belongs to bears. a bear has walked-- i've seen the telemetry-- through the spot where you and i are sitting right now. and we are within 100 feet of my house. >> whitaker: bryce andrews is a rancher, author, and field director for a non-profit called

people and carnivores, which tries to minimize human-bear conflict. he's seen all the videos of grizzlies going through trash cans, raiding chicken coops and backyard bird-feeders, even the fridge. they are true omnivores, and really hungry from the moment they emerge from hibernation each spring. >> andrews: anything with caloric value, a bear will turn it into what they need to survive. >> whitaker: so they will eat any and everything. >> andrews: any and everything. they'll come for bird seed. they'll come for the residue on a barbecue. >> whitaker: it's their appetites that get them into trouble with humans. >> andrews: absolutely. ( growling ) >> whitaker: the greatest trouble comes when grizzlies go after livestock or crops that ranchers and farmers count on for their livelihood. >> cooley: bears can be really hard to live with. they kill livestock. there are producers who have 20, 30 cows a year killed by grizzly bears.

and so, for those folks-- >> whitaker: sounds like a lot. >> cooley: it's a lot. it's a big impact. >> greg schock: the bears probably knocked down between 20% and 25% of my corn that i couldn't harvest every year. >> whitaker: greg schock farms in montana's mission valley. he says grizzlies live in the woods about a mile from his home. >> schock: we had 18 several years in a row in our cornfield and nobody believed that i had that many until they put cameras up and actually had footage of them. >> whitaker: 18 in your cornfield? >> schock: in a 100-acre cornfield, yeah. >> whitaker: with so many grizzlies around-- now nearly 2,000-- the federal government has considered removing some populations from the endangered species list. so far, court challenges from environmental groups and native americans have prevented that. you think it is possible to coexist? >> schock: i think we have to. if we don't coexist, what's-- who's leaving? the bears aren't leaving, and we aren't leaving. so...

>> whitaker: so, bryce andrews' organization does things like install high-voltage electric fences around fields, like this 30-acre melon farm. grizzlies are smart enough to "test" the fences, and sometimes even get around them. >> andrews: we've got an electrified gate, here, which is off right now. >> whitaker: andrews has an electric fence around his backyard chicken coop. but not all of his neighbors do. >> andrews: generally, when there are unprotected chickens in grizzly habitat, it's only a matter of time before something goes wrong. >> whitaker: the grizzly bear will win. >> andrews: they'll win, and see, they have these phenomenal noses. they smell everything. >> whitaker: including neighborhood trash cans. if a grizzly develops a taste for garbage, gets accustomed to being near people, and then teaches those bad habits to her cubs, it can prove fatal. bears that get into such trouble are often trapped by state bear managers.

at first, they're relocated to remote regions and released. but, if they keep coming back, federal official hilary cooley may need to authorize killing them. >> cooley: ultimately, that's my decision. >> whitaker: what's that like? >> cooley: it's the worst part of the job. it's-- but it's necessary. >> whitaker: why "necessary"? >> cooley: if we think it's a threat to human safety-- for example, a food-conditioned bear-- bears can kill people. and it's something we don't mess with. if there's a threat to human safety, we remove it right off the bat. >> whitaker: and remove, you-- >> cooley: euthanize. >> whitaker: euthanize. she had to authorize the killing of nearly 50 grizzlies in 2019. the grizzly bear we saw erik wenum tranquilize in the swan mountains may never have seen a human being before, let alone gotten into trouble. do you know, is it a male or a female? >> wenum: i don't yet.

>> whitaker: how long will this grizzly be out? >> wenum: about an hour and... >> whitaker: about an hour. >> wenum: 20 minutes... argh! >> milan vinks: it's a male. >> whitaker: why-- why were you hoping for a female? >> wenum: we want to radio- collar females. females drive the system. they-- they really do. >> vinks and wenum: one, two, three. >> whitaker: will you collar him? >> wenum: we collar some males. we're not going to collar this guy, though. >> whitaker: boy, look at those claws. the forest becomes a field hospital, as they attach monitors and even an oxygen bottle to the grizzly. >> wenum: so he's at 88% oxygen. i like it when it's 90%, 95%, so i want to get him up. >> whitaker: we measured every part of the bear. >> vinks: five and a quarter, okay. >> whitaker: blood is drawn, tufts of hair pulled for d.n.a. analysis. >> wenum: i'm going to call him a five-year-old bear, okay? so you can see, these are his

incisors, and if you run your fingernail over the top, you can still feel some cusping. >> whitaker: tell me i can do this? stick my hand in a grizzly bear's mouth? >> wenum: i'm telling you, you can do that. >> whitaker: oh, yeah. how about that. less than an hour after being darted-- a bit ahead of schedule-- the grizzly starts to stir. he's moving a little bit over here. so he's starting to wake up-- >> wenum: okay. everybody, we're ready to go. you guys head on out. everybody go. >> whitaker: we didn't need to be told again. as we hustled out, wenum removed the hood from the bear's head, and hurried out himself. >> wenum: your first question'll be, "does that happen often?" ( laughter ) >> whitaker: yeah, when he was sniffing up, that was time to go-- >> wenum: when he was lifting his head, it's time to go. >> whitaker: it's time to go. we had about as safe an encounter with a grizzly bear as is possible to have. but with more people going deep into bear country, to hike or bike or camp or hunt, there are several decidedly unsafe

encounters every year. >> anders broste: i didn't really get a warning, and all of a sudden there's a grizzly bear running at me. and in about probably less than a second, it was on me. >> whitaker: anders broste was hunting for deer and elk with a friend in the wilderness north of his montana home on november 11, 2018 when he stumbled upon a grizzly who'd been dozing in the snow. >> broste: it bit my arm here, kind of thrashed it around. and then bit my leg here. started pulling on me and kind of tossing me around. and then it just dropped my foot and ran off. >> whitaker: do you have any idea why he didn't just finish you off or drag you off? >> broste: nope. >> whitaker: broste's hunting partner dan reached him within a minute or two. luckily, they had a cell phone signal to call 911. state bear specialist erik wenum was one of the first responders on the scene, and he snapped a photo of a very large paw print in the snow.

they had to chopper you out? >> broste: two choppers. >> whitaker: how long were you in the hospital? >> broste: i was in the hospital for six days. in that six days, i had three different surgeries. my arm was broken, my thumb was broken, and my hand was dislocated. my foot was basically held to my-- my ankle with soft tissue. >> whitaker: this is the grizzly that attacked anders broste, in a photo taken four years earlier when state bear managers trapped and released him. d.n.a. samples proved the match. so, the bear that attacked you is still out there. >> broste: yep. >> whitaker: does that bother you? you okay with that? >> broste: i'm okay with it. i was intruding. so, to me, the bear's response was not any more inappropriate than what somebody else's response would be if i trespassed into their home. >>hita b who's the co-founder of mpes, back on his, after many months of tough rehab. and he says he and his friend

dan plan to go hunting again this november 11, the anniversary of the attack. >> broste: i think it's part of what makes montana wild. if we didn't have grizzly bears, like, it'd be a little less wild. and i think that's kinof cool.a. i'd-- i'd prefer not to see one that close again, though. ( laughs ) >> whitaker: two people have been killed by grizzlies in montana so far this year-- a man, attacked in april while fishing; and just last month, a woman who was pulled out of her tent by a bear. both grizzlies were found and killed by authorities.
