And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Dockworkers examining RMS Titanic’s triple screws as she lay in dry dock, Harland and Wolff Shipyards, Belfast, 1911 or 1912.
Titanic's design was pressing the limits of the technology of the day when she was built. Her rudder was 78 ft. tall, but only the lower half was in the water to turn the ship. Being just 15 ft. long, she was proclaimed to be slow to answer the helm during large steering inputs to the wheel. Only her two outboard screws were capable of being reversed in case of an emergency. So, here's a 900' long, 100' wide 60,000 ton steel behemoth cruising at 25 mph that lacked the ability to get out of her own way due to her turning radius being rated as "eventual". What could possibly go wrong ?
Engineers! Gotta love us!
