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 an$ 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.
