>> 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 are 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 and even felt by a commercial airplane on approach to the las vegas airport. >> as that shockwave went across

the desert, anything its path was leveled, 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? get out of there. >> when "caught on camera: total destruction" continues.

the plane ta that happ is in. >> when it hit us, it was nothing. i felt a little bump. nothing like when you run into a telephone pole backing up out of a parking place. but then we did 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 it tried to evade the weapon. i did not realize it had taken off the wing. i thought that we just needed to recover the airplane, and lost control 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 could see was black and gray. i didn't realize at the time that our canopy had glazed over. 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 the emergency rocket-propelled emergency ejection seat. >> 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 evacuate seconds before impact. >> i don't remember coming out of the airplane visually. i felt the snap of the parachute, and that is when i opened my eyes finally or i could see again. grabbed ahold of my parachute and looked up and saw the big

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 condition 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 that layer up into one line. 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 ever happened to me by far. i never felt scared. everybody says, well, weren't you petrified? actually, no. i didn't have time to think about being scared.

amazing action, unbelievable rescues. a mother and her children trapped inside the twisted wreckage of a car. >> it did go through our minds that this vehicle could go over the edge. >> firefighters who demonstrate courage any time any place. >> basically you're hanging 80 feet beneath the helicopter which was not the plan i had in my mind. >> we first got on the scene and looked over the edge, and it was like oh, this is a lot bigger than we thought. >> acts of bravery from every day heros. >> i heard a yell for help and i just immediately started running for the door
