Plans to build world’s deepest pool in Cornwall to train astronauts

Blue Abyss applies for permission to build 150m centre with pool that would reach depths of 50m

Plans have been submitted to build the world's deepest artificial pool in Cornwall to train astronauts and help advance undersea robotics.

The project would be 40 metres by 50 metres at the surface, with a 16-metre wide shaft plunging to 50 metres at its lowest point - nearly as deep as Nelson's Column is high - and would also be the world's largest pool by volume.
