James Cameron Begins His Deep-Sea Dive

James Cameron is on his way down. The director's long-planned trip to the deepest spot on Earth — the Mariana Trench's Challenger Deep — is in progress; by the time you read this, if all goes well, Cameron will be navigating around in depths unvisited since 1960. National Geographic's coverage of the dive is excellent as well, as is the BBC's (with video).
