>> may 4th, 1988, henderson, nevada, just ten miles from the las vegas strip. dennis todd is doing routine repair work on a tv transmission tower on the top of black mountain when he notices an extremely bright fire down below. >> we looked down and saw this fire with this brilliance, like a fourth of july sparkler. unlike anything i've seen before. >> the fire is so bright because it's fueled by a highly volatile chemical used to make rocket fuel. todd grabs his video camera and begins recording. >> i set it on a tripod, pointed down at the fire, and went back to eating my lunch. >> the fire has broken out at the pacific engineering and production company, known as pep con, where the chemical is manufactured for the space shuttle and military rockets.

>> the solid rocket motors of the shuttles that take off are filled with ammonia perchlorate. you have a material that in this case can really detonate, explode. >> pepcon employees, knowing just how explosive their factory is, run for their lives. >> the employees know what is happening and they all took off. they self-evacuated across the desert. >> before firefighters arrive, there's a massive explosion. >> oh! >> that's going to be loud. >> i saw the explosion about five or six seconds before we actually heard it. up to this point, that was the biggest explosion i had ever seen. >> firefighters on the way to the scene are stopped in their tracks by the blast and back off. >> the fire chief was driving and got the window blown out. there was a fire truck and the front windshield was blown out. both groups of people were

slightly injured. >> we could see the shockwave coming across the desert and we just ducked down, tried to get under the dash. but it was too low. the windshield came out and caught me in the forehead. >> others ten miles away in las vegas hear and feel the shockwave. >> we honestly thought that there had been some kind of an airplane crash or something like that. >> but the biggest blast is yet to come. several additional fire departments respond. >> we were en route to the disaster site. and as i started realizing the magnitude of the disaster that unfolded, the thought occurred to me that i could lose my life here today. >> the chemicals are not the only combustible material fuelling the out of control fire. underneath the facility is a natural gas line that ruptures and ignites, making the blaze virtually unfightable. fire officials evacuate a five-mile radius around the plant.

>> oh, there's another one. they had all of that fuel stored out there in barrels. >> and another one! >> geez! >> then the fire penetrates the main storage area of ammonia perchlorate and unleashes one of the biggest accidental industrial explosions in american history. >> wow [ bleep ] loud! [ explosion ] >> it was incredible. i think most people agree that it looks like some kind of a nuclear detonation. it's the most amazing thing. >> the shockwave ripples across the desert, blowing out windows and doors in homes and businesses throughout the cities

of henderson and las vegas. >> the plant was pretty close to a mountain range. and when the pressure waves went out, it rebounded off the mountain and came back with even more force. >> nearly everybody you talked to, no matter where they were at in las vegas, felt a tremendous hit. we realized that this was a serious, huge disaster. as you can see the damage, it really began to hit home. >> dennis todd watches from the mountaintop in disbelief. >> i was not ready for the mother lode explosion when it came. it looked like nothing that i had ever seen before. >> the explosion kills two people, one whose body is never found. both are employees of pepcon who don't make it out in time. more than 350 people are injured. >> i remember one person describing it as, they were on a run, just a dead run away from

the facility and as the shockwave of the blast, you know, hit them, they ended up basically opening their eyes and they were on the ground. >> the blast consumes most of the remaining chemicals and there are no more explosions. the natural gas line is shut off and the fire burns itself out by the next day. >> and nobody can believe it. i think there was a realization from the residents of henderson that they had a dangerous industry right in their backyard and nobody stopped to think about it before a disaster of that magnitude. a marshmallow factory next door is leveled by the explosion. fortunately, all its employees evacuate beforehand. but it creates a sticky situation for firefighters who search through the debris. >> all of us had brown syrup all over our safety gear and pretty much saturated with marshmallow syrup. kind of a brown, sugary syrup. >> 200 miles away, the final explosion measures 3.5 magnitude at the california institute of

technology in pasadena and is even felt by a commercial airplane on approach to the las vegas airport. >> as that shockwave went across the desert, anything in its path was levelled, destroyed, disturbed. >> an investigation finds the fire is started by a welder's torch during maintenance and is spread by chemical residue that causes a fiberglass wall to ignite. the plant is rebuilt in utah and a power substation eventually takes its place in nevada. those that experienced the disaster firsthand will never forget it. >> the last explosion and the shockwave is burned into my brain forever. coming up -- workers moving a building run into serious trouble. and truckers make big mistakes. >> i'm thinking, what are you doing, guy?

people are shocked when an office building inexplicably falls over and crashes into the street. july 23rd, 2004, the philippines. an alarming situation develops when the eight-story building leans precariously over, one of the city's main shopping districts. age is not the problem. the building is just five years old. but the modern structure has been leaning over the street for several days and is now in critical condition. fearing the worst, authorities evacuate the building and other buildings in the area. the busy street is cordoned off and camera crews record the scene from both sides of the

street. then, just a few hours after everyone gets out of the building, it falls over. the building brings down power lines and kicks up a huge cloud of dust and debris. the collapse leaves a mound of rubble about half as high as the original structure. no one is injured. an investigation determines that flawed design and faulty construction, particularly with the building's foundation, are the main reasons for the collapse. across the globe, a much older and smaller building, a

122-year-old brick fire house, is being moved to a new location when something goes terribly wrong. the historic firehouse crumbles into a pile of rubble. august 21st, 2008, peekskill, new york. after months of planning, workers begin the slow and delicate operation of moving the firehouse. the firehouse, built in 1890, is home to the centennial hose company. it serves the peekskill community for 90 years before closing in 1980 because of recurring problems with flooding. >> every time we had heavy rains, it would flood out our firehouse. we used to be knee-deep, sometimes chest deep in water in the fire station. >> despite decades of neglect, firefighters cherish the centennial and the memories it

holds. but to make room for a new bridge, the centennial is scheduled to be demolished. instead, the city of peekskill decides to move it down the street and turn it into a museum. however, moving a 122-year-old brick building is not easy feat and firefighters were concerned. >> i was kind of skeptical as to whether it would be able to be moved or not. >> a local video production company decides to document the move and a professional videographer sets up his camera and begins recording the scene. >> they were turning the building 90 degrees so the front of the building would now face another direction so they could retool and get it to its new location. >> across the street from the firehouse, bobby, an employee at dane's lumber, repositions the store's security camera to capture the massive endeavor. >> just in case there was a mishap, i wanted to make sure that i had the camera pointed at the firehouse so i could have a

record of it. >> as soon as workers begin rotating the fragile building, it falls apart. >> all of a sudden you heard a pop and the whole building just leaned. what probably amounts to maybe three seconds it was on the ground. >> a huge cloud of dust and debris surrounds the area and onlookers fear that workers are hurt. >> do you believe that? >> yeah. >> oh, man. those guys were all around that. >> there was about 20 workers and the company itself was a father and son team. and the son can be heard vividly on the video screaming where's my father? where's my father? as he ran down from one side of the building. >> where is my father? >> he got out. he's all right. he got out. he's over there. he's over there. >> workers scramble to see if anyone is trapped or injured.

>> within less than five minutes, all of the men knew that everyone was accounted for. and then at that point it just became cleaning up, getting the police department, fire department down. >> an investigation concludes a hydraulic lift supporting the mobile platform fails when the firehouse is being rotated to clear power lines. to honor the centennial's history, some of the bricks salvaged from the building are displayed in a trophy case at the current firehouse. coming up, the roof of the milwaukee brewers' new stadium comes crashing down. >> there was nothing you could do. it was terrifying. and a massive storm floods more than a basement when "caught on camera: total destruction" continues. cigna covers preventive care. so you can also take care of yourself, for them.

foundation, the wash had undercut it, and about a third of the house was completely out in the air. >> all eyes and cameras are on the beige house with white trim. no one is inside. the owner just completed construction and hasn't moved in yet. >> it's not finished yet, nope. >> i just talked to him and he said he just finished painting it and he was laying down the floor. >> there it goes. >> then, the unfinished house is finished forever. >> we knew it was coming. the sound is extremely eerie. the cracking, the popping -- >> the house shears off from the garage and falls into the river. >> wow. >> wow. look at that. pretty sad. >> it starts floating away but then rams into the neighbor's house.

>> when it hit it and spun it around, i thought the house would then kind of fall apart, but it continued down the river. >> everyone is stunned as the well-constructed house stays together. >> the walls were still intact, the roof was intact. and it floated down the river like a boat. >> it was hard to believe that a home would stay whole like that and just go down the wash like it did. the guy that built it must have built it very well. >> firefighters wish there was more they could do to help. >> when the house started going down the stream, it's just very emotional at that moment. >> just felt bad for the owners. i don't know how else to describe it. just felt bad for those guys. >> incredibly, the house continues making way down river. >> it stayed pretty upright, it didn't wobble. it just looked like somebody could have been in the kitchen cooking. it didn't appear to be a rough ride. >> but its voyage doesn't last forever. the house gets tangled up with a tree.

the turbulent water smashes against the house causing it to break apart. >> i'll bet if you go down there with a metal detector, you'll find washers, dryers, all kinds of appliances, maybe some silverware. >> after taking quite a beating, the house is gone. >> just disappeared. i did several flights over the area and we could see pieces of roof downstream. a lot of just debris. you know, after they broke up. >> justin rushes to get his video on to the newspaper's website. the amazing footage quickly goes viral. >> i just uploaded the clip raw. it was by far the most popular on the website in the three years i've been with the "las vegas review journal". >> watching the destructive powerful nature is a humbling experience for the firefighters. >> we still talk about it.

in a wrongful death lawsuit against the contractor mitsubishi heavy industries of america. a jury awards them nearly $100 million in punitive and compensatory damages, calculated in part from the video. >> from the video, we were able to time how long it took for the crane to go down where these guys fell to their death, 14 seconds, and the jury was asked to award per second what their conscious anticipation of death meant to them because they knew they were going to die. >> the verdict is appealed and eventually settled out of court. the stadium, named miller park, opens nearly two years after the accident featuring the only fan-shaped retractible roof in the country. a memorial to the men who lost their lives greets fans when they enter, ensuring the three

test flight photographer is filming an f-18 hornet from a chase plane. >> it was basically filled with concrete. the mission was to find out how the mark 82 would separate from the airplane in an emergency mode. >> dozens of other cameras are also recording the critical test of the navy's newest fighter jet. >> they are all stuck all over the airplane and then i'm there as the insurance policy. if something goes wrong and they lose the airplane, they have my film that can come back and reassemble what happened. >> little does he know, it's his plane that will run into trouble. when the planes ream 5,000 feet, the hornet releases the bomb while flying at more than 500 miles per hour. >> we had just gotten into position and as the weapon came down it came right on its side and took our right wing off. >> a slow motion camera on the f-18 records the bomb shearing

off part of the chase plane's wing, the plane hepp is in. >> when it hit us, it was nothing. i felt a little bump. not even like when you run into a telephone pole backing up out of a parking place. nothing drastic. but then we did two 360-degree rolls in less than a second and a half. so that got my attention. >> hep and the pilot are the only two people in the plane. as they spin wildly around and around, their plane becomes engulfed in flames. hep doesn't know the plane is on fire and critically damaged. >> i thought, oh, we lost control because he tried to evade the weapon. i didn't realize it had taken off our wing. i just thought we recover the airplane, thought we just lost control of it a little bit. i thought, okay, we're good. we're going to fly it and land. >> as they continue their fiery spiral towards earth, his vision gets blurry. >> i could not see anything.

all i saw as black and gray. i didn't realize at the time that our canopy had glazed over. inside the fireball it all crystallized and i didn't realize that we were on fire at that particular time. >> the plane slams into the ground. then a camera scans the sky and finds hep and the pilot parachuting to safety. they activate their emergency rocket propelled ejection seats in the nick of time. >> i saw the fire and i said, okay, i think it's time to get out. i'm no longer having fun. i'm going to eject myself. >> he and the pilot shoot out from the doomed aircraft seconds before impact. >> i don't remember coming out of the airplane visually. i felt the snap of the parachute. that's when i opened my eyes finally or could see again. grabbed ahold of my parachute

and looked up and saw the bill circle and said, okay, i'm happy now. i said some other words, too. >> they float to safety and incredibly both are okay. an investigation reveals several problems. the biggest being that the chase plane isn't in perfect position when the hornet releases the bomb. >> we were just about in a very safe position before the weapon was released. we thought we could make it. there's also a whole bunch of what we call layers of swiss cheese that are involved in a mishap. it's all of those little things finally pile up into one line. call it the layers of swiss cheese. the holes line up and you have a problem. >> hep's camera and film are never recovered. he works as a test flight photographer for 28 more years. >> this is the worst thing that's ever happened to me by far. i never felt scared. everybody says, well, weren't you petrified? i says, actually, no. i didn't have time to think
