Virgin Oceanic Sub

Over the course of 2011 and 2012, Virgin Oceanic’s one-person sub will journey to the deepest part of each of Earth’s five oceans. The first dive will be to the deepest place on the planet: the bottom of the Mariana Trench – 11 kilometers (7 mi) straight down. This will be the first time since 1960 that human eyes have set sight here – when the bathyscaphe, Trieste (which moved straight up & down like a hot air balloon) briefly touched down carrying co-pilots Don Walsh and Jacques Piccard. This time, a sub that flies more like an airplane will allow the solo pilot, Chris Welsh, not only to reach the deepest point on Earth, but then to “fly” along the bottom of the Trench an additional 10 kilometers (nearly 6 mi).
