The desperate search for a submersible that disappeared while taking five people to view the Titanic wreckage has drawn attention to other deep-sea rescues.
Those rescue efforts — from a submersible off Ireland to a submarine off the New Hampshire coast — offer some measure of hope for the passengers and their families. But some of those rescues were not as complex as the effort to find the Titan submersible. They were often in shallower waters and, in several cases, were much bigger crafts. Many ended with some, if not all, the passengers on board dying — demonstrating the inherent risk of operating in the deep ocean.
