26 of April, 1986. Two explosions happened on the 4th energy block of Chernobil's Nuclear Powerplant. Catastrophe stroke this nuclear object. Scientists proposed to tightly shut reactor with on top protective layer of sand. But it was impossible to approach the emergency block from anywhere, except than from the air. And only helicopters could execute this task. Temperature reached 200 degrees. Radiation exceeded all norms by thousands of times. In such tragic circumstances helicopters and people, who controlled them, have show what they are capable to do. Following helicopters are featuring in this film: Mi-6, Ka-22, Mi-10, Ka-25, Mi-8, V-12, Mi-26, Mi-2, Ka-26, Ka-27/32, Mi-14, Mi-17, Mi-24, Ka-29, Mi-34, Ka-226, Mi-28, Ka-50 "Black Shark", Ka-52 "Alligator", Mi-38 "Ansat". - This is a documentary of "Wings of Russia" studio about history of development of Russian Aviation. It contains a lot of unique video footage. The documentary speaks about creation and development of fighters, bombers, helicopters, reconnaissance planes, hydro-planes, planes of civilian Aviation and also about sport and training Aviation, in the USSR and Russia.

Iceland is an island born of fire and ice with white glaciers, black beaches and green meadows: a land of geysers, waterfalls and volcanoes. Reykjavik is set amid a fascinating landscape, a metropolis on the outermost edge of civilisation and the world's northernmost capital city. A little outside the city is an attraction that is a meeting place for one and all, The Blue Lagoon, the largest bath tub in the world! The mineral water it contains has a temperature of forty degrees centigrade and the milky-blue pool has been proven to possess beneficial healing qualities. Southeast of The Blue Lagoon is Hveragerdi that is set within an idyllic valley. Due to its protected location and numerous thermal springs, in 1929 a garden city originated there and within its many greenhouses grow vegetables, fruit and exotic flowers. Amid the historic Pingvellir Plains, once the location of ancient gatherings and where justice was administered, is the Öxararfoss Waterfall, the island's oldest Man made device that was used to supply the region with drinking water. On the southern tip of Iceland is the small village of Skogar. The interior of the houses are comfortably furnished and the privately owned Homeland Museum gives a good insight into the daily life of bygone times. Large stones support the wooden sides of the houses, the roofs and remaining walls of which are protected by grass-covered earth. In this area is one of the island's most gigantic and highest waterfalls, Skogafoss, that rages sixty metres into the depths below. The mist above the water cloaks the sight of this mighty natural wonder whose water thunders down across the cliffs of the ancient shoreline with awesome power. Iceland is a fascinating world of water, fire and ice and full of breathtaking beauty and overwhelming contrast. It is one of the last natural paradises on Earth.

It now seems that our entire universe is living on borrowed time. How long it can survive depends on whether Stephen Hawking's theory checks out. Special thanks to Ivan Bridgewater for use of footage. Time is flying by on this busy, crowded planet... as life changes and evolves from second to second. And yet the arc of human lifespan is getting longer: 65 years is the global average ... way up from just 20 in the Stone Age. Modern science, however, provides a humbling perspective. Our lives... indeed the life span of the human species... is just a blip compared to the age of the universe, at 13.7 billion years and counting. It now seems that our entire universe is living on borrowed time... And that even it may be just a blip within the grand sweep of deep time. Scholars debate whether time is a property of the universe... or a human invention. What's certain is that we use the ticking of all kinds of clocks... from the decay of radioactive elements to the oscillation of light beams... to chart and measure a changing universe... to understand how it works and what drives it. Our own major reference for the passage of time is the 24-hour day... the time it takes the Earth to rotate once. Well, it's actually 23 hours, 56 minutes and 4.1 seconds... approximately... if you're judging by the stars, not the sun. Earth acquired its spin during its birth, from the bombardment of rocks and dust that formed it. But it's gradually losing that rotation to drag from the moon's gravity. That's why, in the time of the dinosaurs, a year was 370 days... and why we have to add a leap second to our clocks about every 18 months. In a few hundred million years, we'll gain a whole hour. The day-night cycle is so reliable that it has come to regulate our internal chemistry. The fading rays of the sun, picked up by the retinas in our eyes, set our so-called "circadian rhythms" in motion. That's when our brains begin to secrete melatonin, a hormone that tells our bodies to get ready for sleep. Long ago, this may have been an adaptation to keep us quiet and clear of night-time predators. Finally, in the light of morning, the flow of melatonin stops. Our blood pressure spikes... body temperature and heart rate rise as we move out into the world. Over the days ... and years... we march to the beat of our biology. But with our minds, we have learned to follow time's trail out to longer and longer...
