R.M.S Titanic had on board two Marconi operators--Jack Phillips and Harold Bride who kept the wireless room running 24 hours a day
Titanic was equipped with Marconiamp39s new wireless telegraph system. When the sinking condition of the ship was realised, Captain Smith ordered wireless messages to be sent out to all steamships within reach.
