On one vessel, five people died on a very expensive excursion that was supposed to return them to the lives they knew. On the other, perhaps 500 people died just days earlier on a squalid and perilous voyage, fleeing poverty and violence in search of new lives.

After contact was lost with the five inside a submersible descending to the Titanic, multiple countries and private entities sent ships, planes and underwater drones to pursue a faint hope of rescue. That was far more effort than was made on behalf of the hundreds aboard a dangerously overcrowded, disabled fishing trawler off the Greek coast while there were still ample chances for rescue.

And it was the lost submersible, the Titan, that drew enormous attention from news organizations worldwide and their audiences, far more than the boat that sank in the Mediterranean and the Greek coast guard’s failure to help before it capsized.
