Here's a first hand sense of what it is like down in the deep along side the Titanic from one who has been there. MacInnes was among the first to dive on the Titanic in a submersible back in 1987. I first met him in the early 80's. He is an Oceanographer, Medical doctor, Marine scientist and specialist in high risk, high stress leadership. He agree to chat with me as the frantic search is underway.
