Mystery of the Sands (continued)

Following my blog back last year, when I discovered a mysterious object on our beach, last weekend an object was found (said to be 'a submarine market' or a 'training device', depending which paper you read) - this time a special operations team was flown in from the mainland, the area cordoned off, and the object destroyed by a 'controlled explosion'.  Makes me wonder if it was the same object (missile like) I found on the beach back then, in which case its wandered the local seas for several weeks.  And wonder also why there was such a lack of initiative on the part of police and coastguard last time.  Be nice to see a piccie of said object - nothing on net as regards either 'training device' or 'submarine marker'.  Mystery continues.
