It's found in five pieces near the Titanic on flat surface away from Titanic. (So they ask if it crashed into it?) Imploded Coast Guard Admiral says. Was it blown up? Why did it implode?
They say this sub was not registered by agency to be safe. So privately they can use it, charge $225,000.00 a ride? No one checks it out spending that much money?
I'd like to hear from James Cameron at this time. He has taken 33 trips, with others down to view the Titanic.
WTF happened?
They did also say the banging can be other oceanic noise. However if it just imploded it must have been the loss of communication that triggered all of this from the beginning.
I once knew a guy who had been a sonar operator on a US sub back in the Cold War. He told me that the ocean is a VERY NOISY place, and that he had to be able to pick out enemy sub noises from whale sounds, temperature inversions, and a host of other noises that sonar picked up.
The novel Hunt for Red October talks a lot about this with the character of Jonesey. Very interesting and can explain what anyone here might like to know.
You might also want to read "Blind Man's Bluff"... a true story about Cold War era US subs that were so good and so stealthy that they were able to go right into the Soviet's most sensitive submarine bases and eavesdrop on their conversations. It's a fascinating story, part spy story, part military intelligence, but all good.
“The Silent War” by John Craven is also a good read.
