       | From the photo - the object is a cylindrical tank, with a huge
       | hole in one badly-damaged end of it. It was adrift at sea long
       | enough for barnacles to be growing over much of its surface.
       | 
       | IANARS (not a rocket scientist)...but I'd bet that there are
       | absolutely zero carried-in-tanks-on-rockets toxins which are
       | barnacle-friendly. Ditto ones which would not have been washed
       | away in the first hour of the sea water sloshing in & out of that
       | big hole. And IIR, the intersection of two empty sets is also
       | empty.

         | That wouldn't be known until they confirmed its origin. Finally
         | the content of what could be pressurized is some pretty toxic
