US jet with 4 nuclear bombs crashed in Greenland 50 yrs ago
A US bomber carrying four nuclear bombs crashed in Greenland, a Denmark-controlled territory, on January 21, 1968. While radioactive contents were released due to the impact, there was no nuclear detonation. The US had been flying nuclear weapons over the Danish territory despite Denmark's 1957 nuclear-free zone policy which prohibits the presence of any nuclear weapons in its territories.
