Titanic so fascinating is that she represented the best of technology when she set sail on her ill-fated voyage in 1912,and it took the best of technology in the form of sonar,satellite tracking,and deep-dive technology to locate her grave 73 years later.In the early 1900's,waterborne transportation was the norm; today,satellites are taken for granted by our society.But we tend to forget the immense effort that these two technologies require to operate to their maximum potential.Until recently,the technology did not exist to locate,photograph,and explore this ship that rested two and a half miles down on the ocean floor.
