First of the "Olympic"-class liners, "Olympic" was launched on 20 October 1910 and commissioned on 14 June 1911. She made her maiden voyage on 14 June 1911, under the command of Captain Edward J. Smith, to great fanfare and acclaim. On 20 September of the same year, while under the command of a harbour pilot she was involved in a collision with the cruiser in the port of Southampton, leading to her repair back at Harland and Wolff and delaying the launch of her sister "Titanic". When RMS "Titanic" sank, "Olympic" was on her way across the Atlantic, in the opposite direction. She was able to receive a distress call from "Titanic" but she was too far away to reach her sister before she sank. After the sinking of "Titanic", "Olympic" was returned to dry dock in the autumn of 1912, where she underwent a number of refinements to improve her safety. She then resumed her commercial service.
