Thule Air Base Greenland Encounter 1960
◎Thule Air Base, Greenland
Thule Air Base — home of the Ballistic Missile Early Warning System facing the Soviet Union — experienced a close-range UAP intrusion. An orb hovered over the BMEWS radar installation for 25 minutes. Given Thule's role as the primary nuclear attack warning system, the incident triggered the highest alert classification.
