Standard coaxial cable, not the fiber-optic cable that Ballard hoped to use in later models, connected it to its mother ship. Its video cameras were black-and-white, not color. ✹ The sinking of Titanic: a night to remember At the time it was launched on May 31, 1911, RMS Titanic was the largest and probably the most luxurious passenger steamship in the world. ) Measuring 883 feet (269 m) long by 93 feet (28 m) wide, Titanic potentially could carry 3,547 passengers and crew.

The ocean was as calm as a millpond. The ship’s lights were on and the prow [front end of the ship] went in first. The stern [rear end] was upright for a moment or two. All of the people left on board started screaming, yelling, calling for help. , or JJ for short, could be linked by a second cable to either Argo or Alvin. Carrying lights and stereo video cameras, it could move under its own power, with guidance from the mother ship or from Alvin, to explore undersea geological features or the wreckage of sunken ships.

Big Events did one good thing for Ballard, however: It introduced him to the Titanic Historical Society and that group’s head, Bill Tantum. Tantum, often known as “Mr. Titanic,” soon became Ballard’s close friend. The society could not offer any funding, but Tantum was very enthusiastic about Ballard’s project. He and the historical society greatly increased Ballard’s knowledge of the ship, the people on it, and the events that had taken place on that terrible April night. Through them, Ballard learned to see Titanic as “a fascinating chapter in human history,” as he put it in The Discovery of the Titanic, not just as a means to fulfill a youthful dream and prove his skill as an underwater explorer.
