2. The Baker Test
The Baker Test, part of Operation Crossroads, was the detonation of a 23 kiloton nuclear weapon 90 feet below the surface of the water in the Marshall Islands. The battleship Arkansas was flattened by the blast and hurled out of the water; some say that dark shadow at the right side of the water column is the ship. I’m told that data from these ancient tests is still classified to a high degree.
