After a home run, the splash pad will erupt, and propellers will whirl in a bar.

Of the 1,065 people on board, 30 died when two lifeboats were pulled into the ship's propellers.

Each propeller has bearings with two races, or rings or tracks.

We could hear the whirring of the propellers before we could see the drone - barely visible as it sliced through the sky.

Upon the ship's return to Scotland in September, a gearbox and propeller fault were detected, and further investigation at Dale's Marine in Greenock revealed the rear of the ship was twisted.
