MAXJDA,
The problem this company is having is creditability. In one PR they claim that their researcher has a manifest that says between $50,000,000 and $300,000,000 worth of treasure is on the wreck. In an interview later on, the CEO of the company states that the wreck is Historical in nature and "IF" there is any treasure on it, it would be a plus.
Excerpts of a manifest would not be out of question in this case.
You are right about one thing. Another treasure hunting company would never have left the site in the first place. If it was bringing up treasure and THEY KNEW that there was 10's if not 100's of millions of dollars worth of treasure on the wreck.
A clear example would be Odyessy Marine. They brought up the treasure. Never left the site and then made the announcement.
