Two large shipping containers, stamped with the words “Contains: Guided Missile,” were discovered in the Pacific Ocean near Alaska Sunday.
Alaska State Troopers said the containers were empty, and information from tags attached to the boxes was sent to the U.S. military. There was no immediate public comment from military officials.
Troopers were investigating the discovery of one suspicious box when they got a radio message from another mariner that a second container had been found. Both were found near the southeast island community of Craig.
Clinton Cook Sr. told KTUU-TV he was on a charter boat that found one of the heavy, hard plastic containers. They were going to pass it, but noticed the unusual shape.
"I seen the data plate," Cook said of the plastic box. "It said, 'Contains: Guided missile.' And I was like, 'Holy crap.'"
Cook told the station he was traveling to a job site to lay propane pipes in the Steamboat Bay area when someone saw the object. The crew initially thought it was a float.
Troopers say an explosives ordinance team helped determine the boxes were "void of their original contents." Troopers didn't know any history of the containers.
