Last month, James Cameron ventured where few had gone before, to the bottom of the Mariana Trench, the deepest point on the planet. Last night we got a first-hand account of the journey from the man himself on the National Geographic Channel.

It is said that Cameron intends to make a feature length 3D documentary detailing what went into the dive, but NatGeo was treated to the juicy bits in advance. There were definitely some obstacles to overcome, but Cameron lived to tell the story, which is all you can ask for after such a feat. [NatGeo]
