An Unsinkable Titanic - Every Ship its own Lifeboat #719057

Among the many questions which have arisen out of the loss of the Titanic there is one, which, in its importance as affecting the safety of ocean travel, stands out preëminent:
"Why did this ship, the latest, the largest, and supposedly the safest of ocean liners, go to the bottom so soon after collision with an iceberg?"
The question is one to which, as yet, no answer that is perfectly clear to the lay mind has been made. We know that the collision was the result of daring navigation; that the wholesale loss of life was due to the lack of lifeboats and the failure to fill completely the few that were available; and that, had it not been for the amazing indifference or stupidity of the captain of a nearby steamer, who failed to answer the distress signals of the sinking vessel, the whole of the ship's complement might have been saved.
But the ship itself—why did she so quickly go to the bottom after meeting with an accident, which, in spite of its stupendous results, must be reckoned as merely one among the many risks of transatlantic travel?
