The future friendship of the US with Greenland will be similar to its past.

Plane crashes through ice with H-bombs
23 January 1968

An American B-52 bomber, believed to be carrying four unarmed hydrogen bombs, crashed in Greenland yesterday. The Pentagon admitted today that the place was carrying nuclear weapons but it declined precisely to identify them. It is believed that the bomber crashed through the ice and took the bombs into the freezing water.

In Copenhagen the Danish government made no attempt to conceal its concern at the incident. The prime minister, Mr Krag, called on Washington for more information and reiterated that his government prohibited nuclear weapons on Danish soil. He added: “This applies to Greenland as well and consequently no aeroplane carrying atom bombs can pass over Greenland territory.”

Radioactive ice cleared by airmen
4 March 1968

United States airmen with shovels and axes have begun the task of moving tons of radioactive snow and ice from the area in Greenland where a B-52 aircraft carrying four hydrogen bombs crashed last month. The snow and ice will be placed in 18,000 gallon sealed metal containers and stored at the Thule airbase in Greenland until it can be removed by ship this summer when Greenland’s coast becomes passable.
