On this day September 1, 1985, the wreck of the Titanic was found 400 miles east of Newfoundland. The Titanic was a passenger liner that started its maiden voyage from Britain and subsequently sank in 1912 after hitting an iceberg. Over 1,500 people died when she sank and it has become one of the most famous maritime tragedies of all time.
Finding this wreck was mostly likely an exciting, yet stressful situation. Knowing that over 1500 people died on this ship can be an overwhelming thought and boxed breathing may have help these explorers to calm their bodies.
