tonka97:"On the S-5 episode, the 'detectives' neglected to mention that the Navy conducted 477 dives on the wreck. After a throrough investigation, there was never any doubt that the submarine sank as the result of a malfunction of the main air induction valve. In addition to instituting changes in the design of this essentially important valve, the Navy installed indicating lights in the control rooms of other submarines, to show when the valve was open or closed"....
"They (deep sea detectives) exclaimed that they saw nothing wrong with the valve. First of all, the main air induction valve was not located in the control room, (where they were) but in the engine room. The valve that was shown in the broadcast was some other valve."
"Secondly, they should have known that the component that failed was the gate inside the valve, and that this mechanism could not be seen by looking as the outer casing".

Chatterton and Kohler have a lot of experience in fooling the gullible with Shadow Divers and Hitler's Lost Sub. They shamelessly continue to chortle all the way to the bank.
Considering the source you're quoting, I'll go with Chatterton, thanks just the same. Lots more credibility.
