Titanic Beneath exhibition recreates sight of doomed ship on sea bed

On the 32nd anniversary of the discovery of the wreckage of the Titanic, Conor Kane talks to an underwater explorer, the first Irishman to set eyes on the doomed ship on the bottom of the ocean floor.

You’re in a thick-walled, 18-tonne, submersible craft in a space spanning less than 3m in diameter with barely room for three people.

It’s hot at first, then you venture for two-and-a-half hours from the surface of the ocean to its depths, two-and-a-half miles from sea level, and by now it’s very cold.
