In this episode, we venture into the Pacific Ocean, specifically to Elugelab, a part of the Enewetak Atoll. Elugelab, a seemingly unremarkable 45-acre landmass, carries a history linked with one of the defining events of the mid-20th century. The episode takes us back to November 1, 1952, the last day of the island's existence, when it became the test site for the first hydrogen bomb ever, codenamed MIKE Shot.
