8. Broken Arrow, Greenland
The term broken arrow means damaged or a fallen nuclear weapon and is widely used by the military of the US. It’s also a site located in Greenland which is highly pixilated by the Google maps. In 1960-1968, the air force of the US carried out a secret and highly classified operation. It was during the Cold war and that mission was called “The Chrome Dome”. This operation involved some accidents of B-52 bombers which had thermonuclear weapons. The accident led to the end of that program in the year 1968. It is presumed by many that those accidents lead to the poisoning of much military personnel by radiations but no reason behind pixilating is known as such till now.
