Jack Phillips and Harold Bride were the wireless operators on the ill-fated cruise ship Titanic. Working in shifts, they sent company messages, weather reports, and telegrams twenty four hours a day.Employed by Marconi, they answered to the captain and were considered a frivolous addition rather than the essential staff they would prove to be.Meanwhile, on Carpathia, their friend Harold Cottam worked alone, snatching sleep when his workload allowed. Captain Arthur Rostron loved technology and marvelled at the "sparks" and their equipment.Both ships were crewed by experienced men at a time when radio was a new-fangled curiosity and Titanic was the largest object afloat.This is their story.
