The Atlantic has a great story on the journey of three teams into the Challenger Deep, the deepest point in the known world. Sir Richard Branson, James Cameron and Bruce Jones (Yeah, you don’t know him) all want to reach there.
Director James Cameron is building a submarine that can plunge nearly 11,000m beneath the surface of the ocean. If he can pull it off, he could win a $US10 million X Prize and shoot footage for an Avatar sequel simultaneously.
