Uncovering what is left of Hitler's ambitious structures which were built in a bid for world domination, beginning with a look at the Atlantic Wall. Created in order to protect Europe from an Allied invasion it stretches thousands of kilometres from France to Norway, and on D-Day the fortifications were put to the ultimate test.

Dubai's Burj Khalifa is over 2,700 feet high and the tallest building in the world, and as engineers race to top this record-setting height with cutting-edge tech, a new 3,200-foot-tall building in Saudi Arabia is poised to take the crown.
Join Steven Johnson and consider how the invention of the mirror spurred on the Renaissance, how glass lenses allow us to reveal worlds within worlds and how, deep beneath the ocean, glass is essential to communication. Johnson learns about the daring exploits of glassmakers who were forced to work under threat of the death penalty, a physics teacher who liked to fire molten glass from a crossbow and a scientist whose tinkering with a glass lens allowed 600 million people to see a man set foot on the moon. The link between the worlds of art, science, astronomy, disease prevention and global communication starts with the little-known maverick innovators of glass.
Seaplanes saw the dawn of the aviation industry as they could accommodate large numbers of passengers between continents, and only required a smooth body of water to land. Since the 1920's, advances in floatplane technology saw metal hulls introduced, a cantilevered design and single engine. Seaplanes continue to be an extremely popular mode of transportation.
Two air catastrophes within five months of each other, both involving the same plane: the Boeing 737 MAX. How could these brand-new passenger jets, built by one of aviation's most trusted companies, just fall out of the sky? Now, through newly uncovered records, plus interviews with experts who investigated the crashes, we reveal why this seemingly reliable aircraft was headed toward disaster from the very beginning, and list the series of miscalculations, mistakes, and fraudulent maneuvers that sent 346 people to their deaths in 2018 and 2019.
