"The WWII-Era Experiments Behind D-Day's Success"

Biomedical engineer Rachel Lance's new book, "Chamber Divers," explores the dangerous scientific testing conducted by British scientists at University College London during World War II, which ultimately facilitated the success of the D-Day invasion. The scientists subjected themselves to extreme conditions in hyperbaric chambers, sustaining serious injuries in their research on submarine survival and diving technologies. Their work proved crucial in developing protocols for operating miniature submarines used for scouting missions prior to D-Day, ultimately contributing to the Allied victory in World War II.
