The First Deep-Dive Suit
Deep-sea diving is a crazy experience! All you need is a wet suit, an oxygen tank, and some goggles. At the beginning of deep-sea expeditions, you had to get fully dressed in a suit of armor. It was a crazy and uncomfortable suit that didn't even have a 0% failure rate. This suit was kept under wraps because the US didn't want other countries to get any ideas or steal their patents. This looks horrifying!
