Blowdown is an explosive four part building demolition series profiling some of the most challenging projects of Controlled Demolition Inc of Phoenix, Maryland. Each of the structures, some notable, others notorious is unique and present the team with challenges ranging from the structural, to the
explosive and to the bureaucratic. In episode one, the team from CDI travels to Sellafield, England to take down four outdated cooling towers on the site of the world’s first commercial nuclear
reactor. Sellafield has a long history of nuclear incidents and mishaps dating back to the infamous Windscale Fire in 1957. Sellafield now stores and treats nuclear waste and is home to 90% of Britain’s industrial radioactivity. The tension is increased by the fact that explosives have never been used on an active nuclear site in the United Kingdom before and it has taken four years to overcome the bureaucratic hurdles. The subjects of the film are four nuclear cooling towers. Each one is 88 m high and has an estimated mass of 5,200 tons. Of particular concern is the fact that the towers are only 40 meters away from a nuclear fuel handling plant. There has been a steady deterioration of the towers and there is the concern of an inadvertent collapse. Explosive demolition has been determined to be the safest and most cost effective means of removing the towers.
Each of the towers will be loaded with three sets of explosives. The first set will be in the legs of the towers, encircling 60% of the circumference. The second set will be set in a predrilled band around
the same 60% approximately 20 m up. Charges will also be loaded into 3 vertical slots about 10 meters high which should cause the concrete shells of the towers to deform, rotate and collapse within the drop zone.

With just 10 days to load all four towers, the team struggles safely load and rig more than 4,500 charges and time the explosions to minimize the risks to the surrounding site. The team must evaluate each risk, real or imagined and account for it in the plan. Major concerns are projectiles, ground vibration and air over pressure that could compromise operations at the nuclear facility.

Sardinia has always been the epitome of pure wilderness, an emerald of volcanic origin in the Mediterranean. 1900 meters of coastline and an infinite maze of offshore islands. But Sardinia also has other facets: green valleys, rugged mountains, murmuring brooks, mysterious ruins and a unique fauna.

Just off of Sardinia's coast is an untouched underwater paradise - uniquely beautiful, but also dangerous. Pilot whales, dolphins and mobula rays populate the waters at Capo Testa in the north of the island. In the west, the lagoons of Cabras represent a wild landscape of lakes in which thousands of flamingos live and hunt the red brine shrimps. In addition to the flamingos, grey and purple herons and little egrets breed here. Thousands of bats have found refuge in the craggy mountain world of the Supramonte and Gennargentu, with their countless grottoes and caves.

In the sea we can observe the mass mating of sea slugs, and thanks to our camera robots and submersible boats we were able to observe beard worms with luminous red gills, as well as bright yellow tree corals in the area surrounding the hypothermal lava holes.

Most Dangerous Ways To School - Colombia
In northern Colombia, in the region Bajo Cauca, more than 180 miles north of Medellín, the landscape is marked by water and seemingly endless expanses. Every day, the children who live there face this rough, unpredictable wilderness – with just one goal in mind: making it to school. Because this is their chance to break out of poverty and create a better life. Like the ten year old Kendys and the other schoolchildren.

For this, they subject themselves to a daily dose of danger. Some of them must cross a ramshackle bridge that could collapse at any moment. Like the ten year old Kendys and some other schoolchildren. One false step and they could drown or break their legs.

Ten-year-old Juan does not have to cross the bridge, but first he has to cross a river in an extremely wobbly canoe, and then walk through deep mud full of stingrays. Although his way is dangerous, he’s glad that he can go to school at all. It brings him a little closer to his dream of moving to a big city.

The children face all this under tough conditions. The temperature is already 34 degrees Celsius in the morning, with humidity at 97 percent. In order to get closer to their wishes and dreams, each day these children carry not only a backpack, but also the fear – on one of the world’s most dangerous ways to school.

Whoever wants to experience South America as a nature paradise in a small area, should explore Costa Rica. Almost half of the country is covered by rain forest. Numerous animal species are to be found here like the White faced Capuchin, colourful parrots like the Macaw, Veruga Parakeets and Tapirs.

Also lizards from primeval times have their habitat in this region of the planet. The small central American nation not only fascinates with a rich fauna and flora but also with a wonder world under water. Insights into the fascinating world of the jungle show examples like the epiphytes that make their way to the sky at the expense of her host plant.

A view into the culture of the Indian inhabitants of the rain forest of course does not come too briefly either. A diving excursion through the ocean waters of Cocos Island is the highlight of the journey. The spectator will get flesh crawl while watching hundreds of dangerous hammerhead sharks gliding past the camera.

Neil and the team are on an emergency call out to capture and release a sick Galapagos shark from the Bermuda aquarium.

Follow the team as they risk their lives to transport the shark 10 miles off shore for release in a protected marine reserve.

Watch Neil and the team swim with larger wild Galapagos sharks, studying their behaviour to see if there’s any truth behind their reputation as wild man eaters.

The team also embark on the challenging task of capturing one of these predators to bring aboard the ocean vet boat and attach a satellite tag. This marks the start of a scientific study that will eventually help protect the declining population of this species.

School in New Zealand and Argentina.
Mía lives in Paraguay, but she goes to school in Argentina every day. Miro studies in a rainforest
clearing in New Zealand…
Mía has a long way to go every day to attend school. She lives with her grandparents in
Paraguay, close to the border to Argentina. Many women in Paraguay go to Argentina to give
birth, which makes the children Argentinian nationals and allows them to go to school there.
Mía’s Argentinian school is for free. In Paraguay, she would have to pay tuition. As it is, Mía
needs to row in a boat for an hour and then walk for another one. She is feeling a little weak-
kneed today as well – she is expected to present her home country to the entire class, perform a
dance and even sing a song in her native language Guaraní…
Miro lives in Auckland, New Zealand. Four days a week, she attends a normal public school.
Every fifth day, however, her class sets out into the rainforest of New Zealand – to go to forest
school! There, Miro learns how to start fires, climb trees and play in the mud. Laws of natural
sciences, such as gravity or buoyancy, are taught in a very hands-on manner here. This time,
Miro faces a very special task: Her group is to build a raft. It has to be buoyant enough to take all
pupils safely across the sea. Miro is put in charge of her group. Conflict isn't far off. Will Miro be
able to keep her team together, and will her group be able to launch a functional raft in the end?
