Scientists say that despite a century of technological gains, ships rely heavily on a detection method as old and as fallible as sailing itself ... the eyeball.
We've painted them, tagged them, bombed them, monitored them with radar and watched them from space -- but icebergs like the one that sank the Titanic are still a threat to ships today.
Icebergs can be stealthy leviathans, veiled by rough seas, fog or low light.
Icebergs are very dangerous objects because they drift, they are not stationary, and in higher wave conditions they can be masked or hidden from a ship's radar. That's why they are still a danger to this day.
