On January 23, 1909, two ships -- one carrying Italian immigrants to New York City, the other, American tourists to Europe -- collided in dense fog off Nantucket Island. In a moment, more than 1,500 lives became dependent on a new technology, wireless telegraphy, and on Jack Binns, a twenty-six-year-old wireless operator on board one of the ships. A story of courage, luck, and heroism at sea.
