Robert Ballard, the oceanographer who lead the expedition which discovered the wreck of the Titanic in 1985, was interviewed by Stephen Colbert on the Colbert Report last night. He discusses how the search for the Titanic was a cover for finding two missing nuclear submarines. (See our previous post from June 2010 – Searching for the USS Thresher and USS Scorpion with the Titanic as Cover.) He also discusses the problems of underwater tourism damaging the remains of the Titanic, and an idea to paint the sunken ship to preserve it. Yes, painting the Titanic. An interesting interview, indeed.
