Danger Magnets

第 1 季，第 4 集: They were four inventors who made lives safer for firefighters and police officers, surgery more comfortable for patients, and dreams of flying a reality for thrill- seekers. But before their revolutionary ideas of lightweight body armor, firefighter masks, modern anesthesia, and the wingsuit could be approved, they needed to be put to a life-and-death field test. Meet the men who set out to get rich or die trying, as we celebrate pioneers whose high-risk, high-reward innovations changed the world, and made millions.
