Canary Islands, 1976. Three sailors witnessed a translucent, spherical craft rise up out of the island of Tenerife before departing in a cloud of blue smoke. Three minutes later, 60 miles away on the island of Gran Canaria, 10 different citizens saw the same translucent craft described as "blue" with a "crystalline" structure — three of them, one of whom was in a different location as the other two, told military officials they saw two 10-foot tall beings inside, described as "Swedish/Nordic looking" with diving gear on. The military investigated the entire phenomenon and ruled it "unexplained."
