I think the thrill for adventure must have overtook any doubts over safety concerns.


Something of this magnitude (when you consider how far deep the Titanic is located) should have had much higher safety systems in place. Whether it was the excitement of exploration or the proffit making potential of this business, there should have been much more safety systems and legislation / certifications of equipment in place to ensure these subs could cope.


Even if all comms failed you'd think there would be some sort of manual deployment of an air baloon or something that could rise to the suface and catch peoples attention.


If a plane goes down in the ocean they all have an Underwater location Becacon. These should work in ideal conditions upto 5km underwater and upto 1.5km in worst case situaitons.
Why didnt they have that?!
