singers Rod Stewart, Carly Simon, and James Taylor. One 2005 transatlantic crossing saw Queen Mary 2 carrying, in a locked steamer trunk, the first United States copy of J. K. Rowling's book Harry Potter and the Half-Blood Prince, autographed by the author. In a promotional press release for the event, Cunard said that this marked the first time a book had been transported to its international launch aboard an ocean liner. In January 2006 Queen Mary 2 embarked on a cruise to South America. Upon departure from Fort Lauderdale, one of her propeller pods was damaged when it struck a channel wall, forcing the ship to sail at a reduced speed, which resulted in Commodore Warwick's decision to skip several calls on its voyage to Rio de Janeiro. Many of her passengers threatened to stage a sit-in protest because of the missed calls, before Cunard offered to refund the voyage costs. Queen Mary 2 continued to operate at a reduced service speed and several itinerary changes were necessary until repairs had been completed after the ship returned to Europe in June, where Queen Mary 2 paid a visit to dry dock and the damaged propeller pod was unseated. In November, Queen Mary 2 was drydocked once more at the Blohm+Voss yard in Hamburg (drydock Elbe 17) for the reinstallation of the repaired propeller pod. At the same time, sprinkler systems were installed in all of the vessel's balconies to comply with new safety regulations which had come into effect since the MS Star Princess fire. Additionally, both bridge wings were extended by two metres to improve visibility. After completing the journey around South America, on 23 February 2006, Queen Mary 2 met her namesake, the original , which is permanently docked at Long Beach, California. Escorted by a flotilla of smaller ships, the two Queens exchanged a "whistle salute" which was heard throughout the city of Long Beach. Queen Mary 2 met the other serving Cunard liners and Queen Elizabeth 2 on 13 January 2008 near the Statue of Liberty in New York City harbour, with a celebratory fireworks display; Queen Elizabeth 2 and Queen Victoria made a tandem crossing of the Atlantic for the meeting. This marked the first time three Cunard Queens have been present in the same location. Cunard stated this would be the last time these three ships would ever meet, due to Queen Elizabeth 2'''s
