The reactor lid launched into the sky like a coin. 💥 . . . On August 10, 1985, Soviet sub K-431 was being refueled in Chazhma Bay when a crane misaligned the new core. The chain reaction blew the 12-ton lid off, vaporizing 10 sailors on deck and scattering fuel across the harbor. The bay is still radioactive.
