Hamish Harding, a 59-year-old British billionaire businessman and explorer, is reportedly onboard the missing submarine.
He studied Natural Sciences and Chemical Engineering at Cambridge University and later earned an Airline Transport Pilots License.
As a passenger on the fifth commercial flight of Blue Origin, Jeff Bezos’s space firm, he was described by newspapers as a space tourist last year.
Harding holds the Guinness World Record for traveling around the earth via North and South Poles.
Harding is now the chairman of Action Aviation, an international company which is dealing with sales and operations in the business aviation industry, based in Dubai, United Arab Emirates.
He first announced he was joining the team to see the Titanic wreck in June last year.
