Apparently, for billionaire adventurer Richard Branson, space is no longer the final frontier. Today, he announced his next ambitious project: Virgin Oceanic, which will see the mogul pilot a special ‘flying’ solo submarine to the deepest part of each of the planet’s five oceans — including the bottom of the Mariana Trench, 36,201ft down, a depth no human has yet reached. Backed by an impressive team of scientists and explorers, Branson aims to “collate data and catalogue life forms that will never have been seen before by human eyes and are unknown to science”, according to a blog post he wrote to coincide with the launch. The Virgin Oceanic submarine he’ll pilot uses ‘flying wings’ to propel it downward, mirroring the way dolphins and rays swim.
