Join the team who recover and reassemble the Solid Rocket Boosters (SRBs) that launch the space shuttle into orbit. Technicians, seamen, and engineers catch, recover, and rebuild these critical vehicles, making sure that they are safe to fly every time they are bolted to the side of the launch vehicle. If they don’t get every detail exactly right, disaster can occur: on January 28, 1986, NASA lost seven astronauts in the Challenger disaster as a result of a small fault in one of the SRBs. The risks to those who carry out the SRB work are less publicized but very real, and the job demands everything from open water dive operations to working with high explosives. The launch lasts just minutes, but it’s only the beginning of a process where the lives of astronauts and the health of the entire space program hang in the balance.


  • Mega Breakdown: Train Wreck
    Railroads are the backbone of American industry. 170,000 miles of track crisscross the country from coast to coast, moving two million billion tons of freight nationally every year. But nothing lasts forever, and that includes a couple of 180-ton locomotives. Their engine technology is inefficient - so they're headed for the scrap dealer where they'll be cut down and cannibalized. Any salvageable parts must come out intact for resale, while and leftover metals - like steel and copper - will be cut up, melted down, and ultimately reformed into new products. In this business, nothing goes to waste. Get an inside look at the unknown world of scrap, where locomotives go to die…and be reborn.
  • Mega Breakdown: Miami Super Stadium
    The Orange Bowl, home to the Miami Dolphins and host of five Super Bowls is demolished to make way for a new stadium. Not only is there a tight timetable, everything must be salvaged or recycled.
  • Mega Breakdown: 747 Breakdown
    For years, when a jumbo jet reached the end of its 30-year lifespan, it'd end up in a scrap yard, or rotting at the end of a runway. But at the Evergreen Air Center in Marana, Arizona, planes past their prime are recycled instead. We'll witness each step.
  • Mega Breakdown: Dam Buster
    A team of experts mobilizes to demolish, excavate and recycle a 25,000 ton dam built of concrete and steel. The pressure is on: They have just half the time needed to complete the job. Worse yet, their biggest challenge stands behind the old dam - One million cubic yards of boulders, gravel, and sand that the river has stacked against it for nearly a century. To remove this blockade, the team gambles on a radical, dangerous plan that's never been tried before: Turning the energy of a perfect storm against the debris. If they are not successful, a generation of endangered salmon returning to spawn may be wiped out.
  • Mega Breakdown: Soviet Doomsday Sub
    In the extreme Russian nNorth a team of engineers are ready to dismantle the a Typhoon-class submarine-the world's largest nuclear submarine, the Typhoon. Int its heyday, this monster sub was a terrifying weapon of war-it prowled the oceans of the world armed with 20 deadly nuclear missiles. Now that the Cold War is over, the Typhoon is ready for demolition. But dismantling a submarine with two nuclear reactors is a risky mission. It will take the team over a year to remove the radioactive nuclear fuel, move the submarine into the dry dock and cut its hull into pieces small enough for recycling.
  • Mega Breakdown: Bridge Breakdown
    A young demolition team must lower an historic bridge to recycle 25,000 tons of steel, concrete, and rebar, all while testing their limits, fighting the elements, and racing against a ticking clock.
  • Mega Breakdown: China
    Witness one of the greatest bridge-building booms of all time. Three ultimate bridges call China their home: The Lupu is the longest arch bridge in the world; the Runyang is the largest suspension bridge in China (third longest in the world) and the Sutong is soon to be the longest cable-stayed bridge in the world. Tall enough to straddle huge cargo ships and strong enough to withstand powerful earthquakes and typhoon-force winds, these bridges aren't anything but mega. But to build these structures engineers have to overcome enormous challenges. They battle floods, unstable soil, strong currents, and potential ship collision. See the amazing solutions they must devise to construct three of the world's most astonishing Mega Bridges.
  • Mega Breakdown: The Italian Bridge
    The Piacenza bridge, 40 miles south of Milan1. Since 1949 2 this steel and concrete bridge3 has connected the cities of Piacenza and Lodi4, spanning a remarkable 3,300 feet5 across the Po River6. But in 2009, a dangerous flood causes the Pos water level to rise more than 20 feet7.
  • Mega Breakdown: Speed
    Many predators use speed to survive in the inevitable game of catch-me-if-you-can played out everyday in the wild. Speed increases the odds of winning.
  • Mega Breakdown: Prison
    Break It Down is tackling one of its most formidable projects ever, a building that was made to be virtually impenetrable … the Riverfront State Prison in Camden, New Jersey.
  • Mega Breakdown: Phantom Jet
    The F-4 Phantom has flown in Air Force squadrons from the United States, Europe and Asia. Its speed, agility, and firepower make it one of the most accurate and lethal fighter jets in the world. It has seen action in almost every modern conflict, from Vietnam to the Iran-Iraq War and even the current war in Afghanistan. But even these winged warriors have a shelf life. Some old F-4 Phantoms are used as unmanned drones for target practice, others are decommissioned and broken down - their working parts tested and refurbished for use in other plans. The breakdown process itself takes two and a half months…and is fraught with danger as each plane comes fully loaded with a Vulcan cannon, ejection seats armed with live rockets, and twin turbojet engines. The specialized crew charged with breaking down these parts is well aware of the importance of their job: one wrong move in the breakdown process can damage a plane component. Or worse, injure or kill a technician or a pilot.
  • Mega Breakdown: Train Overhaul
  • Mega Breakdown: NYC Scrap Yard
    In just one day, this family run business will destroy three million pounds of scrap to create a multi-million dollar mound of steel.
