古代外星人理论家认为在数千年前，外星人登陆地球，在那时他们被奉为神明，并且帮助塑造了人类文明。但有什么证据可以证明这种遭遇呢？ Ancient alien theorists believe that thousands of years ago, extraterrestrials landed on Earth, where they were hailed as gods and helped shape human civilization. But what proof could possibly exist for such an encounter? 第十七季 (播出目录) (2021) Season 17 S17E01 失落的秘鲁之城 The Lost City Of Peru (2021年08月06日播出)； S17E02 十大神秘遗址 Top Ten Mysterious Sites (2021年08月13日播出)； S17E03 十大外星人掩盖事件 Top Ten Alien Cover-ups (2021年08月20日播出)； S17E04 沙斯塔山之谜 The Mystery of Mount Shasta (2021年09月17日播出)； S17E05 人体实验 The Human Experiment (2021年09月24日播出)； S17E06 十大外星人遭遇战 Top Ten Alien Encounters (2021年10月01日播出)； S17E07 十大外星文物 Top Ten Alien Artifacts (2021年10月08日播出)； 原未播出的三集转18季播出！

Massive machines require engineering extremes. The massive man-made satellite, commonly known as the International Space Station, hurtling around the Earth at 27,600 km an hour, has been a temporary home for humans for the last 20 years. The biggest land vehicle on earth, a bucket excavator titled Bagger 293, that can move 240,000 cubic meters of dirt each day. Innovation has always meant building bigger, faster, taller, longer and stronger than anything that came before. We’ve seen them in dramatic visual fashion. But how do these actually work? What sets each machine apart. What big ideas drove its evolution and what limitations did this machine overcome? What forces was it built to withstand and where is the breaking point? Using CGI and expert insights, we ‘strip down’ the design of some of the world’s unique colossal machines and reveal mechanical secrets that not only made them work, but also changed the world in a big way! Each episode explores four incredible machines, linked thematically. From sea and space faring designs, to mega airborne, mining and industrial machines, we’ll break down what they can do as well as key inner mechanics and materials that make it all possible. Dynamic archival footage featuring; slow motion, aerials, and time-lapses get us past the ‘caution’ tape and up close and personal with these compound monsters. CGI provides breakouts and blueprints and a look at hidden mechanisms. Adding expertise of structural, mechanical, chemical and forensic engineers to help reveal what’s at stake when these colossal constructions are put work, and how all the pieces come together to make a big impact.
