Imagine a crazy idea. An idea where a solo human being could get into a tiny craft, the likes of which has never been seen before, and drop like a torpedo, 11km beneath the Ocean waves to the deepest hole on planet earth – Challenger Deep. A place where extreme pressure threatens the smallest weakness in any design element and failure equals, at best instantaneous death, or at worst being trapped midway in the water column (5km down) with no hope of rescue.
