Especially as there were known to have been at least six warnings issued on that day.
It's been reported that the iceberg warnings were ignored because the wireless operator was too busy sending out passenger messages via the Marconi wireless room.
But more important perhaps was the iceberg itself. What we have here is not the traditional snow-covered glacier but one that had become clear through continuous melting and refreezing, transforming it into a kind of dark mirror against the calm water and the clear night sky.
It was, you might say, the equivalent of black ice. The Titanic was effectively sailing blind into a trap.
