A B-52 Stratofortress bomber operated by the United States Air Force crashed near Thule Air Base in Greenland. This incident occurred during a period marked by heightened military readiness and tensions between the United States and the Soviet Union. The bomber was carrying a total of four hydrogen bombs, and the crash resulted in the rupture of its nuclear payload, posing a nuclear contamination threat in the vicinity of the U.S. Air Force installation. Following the incident, military units and cleanup crews rapidly mobilized to recover the dropped weapons and ensure the safety of the area. While three of the bombs were successfully located and secured, one remained unaccounted for even after the completion of the extensive cleanup operations. The absence of this bomb raised alarms regarding the safety and security of nuclear materials in vulnerable locations. The U.S. military conducted thorough investigations to assess the environmental impact and to ensure adequate measures were in place to prevent similar occurrences in the future.
