UK tycoon missing on Titanic sub is adventure addict

British aviation tycoon Hamish Harding, one of five people aboard a missing Titanic diving vessel, is no stranger to daredevil antics — and has three Guinness world records to his name.

The United Arab Emirates-based Harding, 58, is the wealthy founder of Action Aviation, a company that buys and sells aircraft with offices in Dubai and London’s Stansted airport.
