Missing Titanic explorer Hamish Harding 'will know what steps to take' before his oxygen runs out, his friend has insisted.
The missing tourist submersible with five people onboard including British billionaire Hamish Harding, has just one percent chance of survival an expert has predicted, but Hamish's close friend has insisted that the explorer will know what to do.
Hamish, 58, is onboard the submarine with four other passengers who all set off to explore the ruins of the Titanic.
