A better comparison is to the round-the-clock coverage of the Chilean miners who were stuck underground, and the boys who were eventually rescued from the cave in Thailand. Your comparison is apples to oranges. The Messenia disaster was over by the time it hit the news (and it was covered extensively in the UK press), whereas the Titan situation was ongoing. Watch how quickly it disappears from the news cycle now it's been resolved.
