Nodule fishing (again?)
 

I am sure many will remember the Glomar explorer and it's "Magnesium nodule" fishing. It was actually fishing for a Russian Nuclear and halfway got it, then the grab broke and they lost it.

Now they are said to be searching for other metals and then will mine it.

Are there any new nuclear subs missing? Would we be fooled again?

Anyone worked on deepsea exploration vessels and has any comment to make?
