Six Soviet sailors were sent from their ship to investigate what they thought was a disabled ship. The sailors rowed their lifeboat into a fog bank and were not found again until 5 days later. The sailors said that as they entered the fog bank a grappling hook had pulled their boat up to a cigar shaped object. They found themselves inside a large circular room surrounded by 20 four and a half foot tall humanoids wearing luminous divers suits. The beings communicated by gesture inviting the sailors to stay. Two accepted the offer while the other 4 remained in a semi conscious state. However one of the men who elected to stay went insane and jumped overboard. Then the four remaining men left in a luminous boat which apparently self destructed when the men were rescued.
