Abstract :
When the RMS Titanic scraped an iceberg on the night of 14 April 1912, its wireless operators began sending distress calls on one of the world´s most advanced radios: a 5-kilowatt rotary spark transmitter that on a clear night could send signals from the middle of the Atlantic to New York City or London. The equipment was owned by Marconi´s Wireless Telegraph Co. and operated by two of its employees, Jack Phillips and Harold Bride.
