Sorry CONF iture, "I can only encourage people to read
these guys too and evaluate if they qualify for the name of nuts ..." does not work. I have. Those idiots don't have a real clue about science, strength of materials, or the difficulty of keeping something secret.
(My hobby during my days at Rockwell International Anaheim was taking very vague hints of what was going on in the black world and noting things like what they were not talking about and telling them what they were doing and offering suggestions. It was fun freaking some of them out when I hit it right on the head. You CANNOT keep something that large a secret. By now somebody should have published information about size of charges, locations, who did it, and all the rest. Some idiot savant like me would have broken the whole thing with details FAR FAR less vague and hand-wavey than those cretins.)
