Series revealing the hidden stories of the deep as a team of four marine experts voyage across the globe to explore our planet’s last true wilderness – its oceans. Over a year, Paul Rose, Philippe Cousteau Jr, Dr Lucy Blue, and Tooni Mahto explore how a unique ocean paradise, home to the greatest variety of whales and dolphins in the world, is under threat. They dive stormy seas to investigate how a giant predator, the cannibalistic Humboldt squid, is invading this sea, and search for the threatened hammerhead shark.In an extraordinary encounter, the team carry out pioneering science on one of the largest carnivores on earth: the 20-metre long sperm whale. They explore a sunken ship with a tragic human story, and search for evidence that the Sea of Cortez is still growing, they dive along part of the San Andreas fault line. The dive is above waters heated to near-boiling point by the furnace of the inner Earth.

The Sukhoi Su-27 (NATO reporting name: Flanker) is a one-seat Mach-2 class jet fighter originally manufactured by the Soviet Union, and designed by the Sukhoi Design Bureau. It was intended as a direct competitor for the large United States fourth generation fighters, with long 3,530 km range, heavy armament, sophisticated avionics and high agility. The Su-27 most often flies air superiority missions, but is able to perform almost all combat operations. Complementing the smaller MiG-29, the Su-27's closest US counterpart is the F-15 Eagle.

The Mikoyan MiG-29 is a 4th-generation jet fighter aircraft designed in the Soviet Union for an air superiority role. Developed in the 1970s by the Mikoyan design bureau, it entered service with the Soviet Air Force in 1983, and remains in use by the Russian Air Force as well as in many other nations. The NATO name "Fulcrum" was unofficially used by Soviet pilots in service. The MiG-29, along with the Sukhoi Su-27, were developed to counter new American fighters such as the F-15 Eagle, and the F-16 Fighting Falcon

In the era of the Cold War, the military planners on both sides of the Iron Curtain were well aware of the threat to their security from both bombers that could carry nuclear weapons and spyplanes. Thus it was deemed essential to have fast fighter aircraft which could intercept and destroy such incoming threats. The MiG-23 was developed to succeed the MiG-21 as the standard Soviet interceptor. It was a major advance on the earlier aircraft. Its swing-wing configuration was a generation on from its predecessor. Deliveries began in 1972 and more than 3,000 aircraft were built before production ended in 1986. As was the case with many Soviet types, the MiG-23 was widely exported to satellite or friendly countries.

Based on a new book, this program unfolds day-by-day, revealing through the letters and diaries of ten people the momentous ten days that led to the Allied invasion of Europe on June 6, 1944. Through the reconstruction of pivotal scenes, the program also details the stories of the three key titans at the top: Churchill, Eisenhower and Rommel. Woven among the profiles of these larger figures are the narratives of ten individuals poised on the brink of the impending invasion - A Canadian infantryman, a German soldier, spies and double agents, a French resistance fighter, Allied commanders and a paratrooper - some of whom are alive today and have given remarkable and moving interviews. With each diary entry, interview, archive segment and substantial reconstruction, the program is propelled forward, closer and closer to the beaches and flak-filled skies of D-Day.
