Professional frogman Courtney Brown tows a 55-foot scale model of the sunken liner Titanic during work on the film Raise the Titanic! (released in 1980.) The screen version of the best-selling novel by Clive Cussler dramatizes an attempt to raise the 46,000-ton wreck of the Titanic, which is 2 1/2 miles down on the floor of the North Atlantic. The model is described as “an exact replica costing $5,000,000.”
