This Engineer Guy video had me riveted for the whole 15 minute length.

Bill shares fascinating images and information gleaned from the 1909 to 1911 editions of the Journal The Engineer. It includes photos of the construction of the Titanic and its twin the Olympic, the launching of these Olympic-class ships, and accidents that occurred. The video includes engineering details of the ship's engines, steering mechanism, and propellers.

The video shares illustrations of the Titanic and its sister ship being built. It was an amazing feat of engineering, and the video does a really good job of showing that.
