@insane.cb: In 1958, Operation Hardtack I featured the "Wahoo" underwater nuclear test in the Pacific Ocean, detonating a 9-kiloton nuclear device 500 feet below the surface. Within seconds of the blast, an immense wall of spray and vapor surged skyward, creating a massive water column nearly half a mile wide and thousands of feet tall. The sheer force vaporized millions of gallons of ocean water instantly, sending powerful shockwaves across the surface and forming an extraordinary aerosol cloud. This terrifying display of destructive power offered scientists critical data on underwater shockwaves, ocean floor impacts, and the potential effects on naval vessels. It remains one of the most visual reminders of mid-century nuclear testing. What part of this explosion shocks you the most?
