Richard Garriott, ever the explorer, has evidently just returned from a deep dive into the depths of the Marianas Trench, the deepest point in the Earth’s oceans.

British-born entrepreneur Richard Garriott has made history after returning from an epic dive to the bottom of the Marianas Trench.

He is the 14th person alive to reach the depths of the Pacific Ocean in the famed trench, but he is the only one to have also flown into space, and been to both the North and South Poles.

Garriott, who was born in Cambridge, spent 12 hours underwater on his journey into the depths of the Marianas Trench, and when he returned said: “Back on the surface! Great dive!”

But: did he place a geocache there, as he did whilst aboard the International Space Station?
