Millä nopeudella

Falling nearly vertical at about 4 mph, the stern crashed into the ocean floor 27 minutes later. The two pieces of the Titanic lie 2,000 feet apart, pointing in opposite directions beneath 12,500 feet of water.

"The streamlined bow section continued to descend at about the angle it had taken on the surface, striking the seabed prow-first at a shallow angle[184] at an estimated speed of 25–30 mph (40–48 km/h). Its momentum caused it to dig a deep gouge into the seabed and buried the section up to 20 metres (66 ft) deep in sediment before it came to an abrupt halt."

Huomattava, että virtaviivainen keulaosa Titanicista upposi huomattavasti suuremmalla nopeudella kuin tylppä peräosa, joka meni alas katkennut puoli edellä. Titanic katkesi kahtia jo pinnassa ja osui pohjaan varsin kovalla vauhdilla, romuttuen lisää, joten kaikki nostamisyritykset oli luonto tehnyt turhiksi jo heti alkuunsa.
