was a technically flawed but historically pivotal nuclear detonation.

While Shot Able was an air burst, the second test (Shot Baker) caused far more severe radioactive contamination due to being an underwater explosion. Displacement: Nearly 1,000 native Bikini islanders were was a technically flawed but historically pivotal nuclear
