For an overall discussion of the history of the salvage legal proceedings, see R.M.S. Titanic, Inc. v. Haver, 171 F.3d 943 (4th Cir. Va. 1999), and related opinions. The results were inconclusive, as three weeks of surveying in almost continuous bad weather during July and August 1980 failed to find the Titanic. The problem was exacerbated by technological limitations; the Sea MARC sonar used by the expedition had a relatively low resolution and was a new and untested piece of equipment. It was nearly lost only 36 hours after it was first deployed when the tail was ripped off during a sharp turn, destroying the magnetometer, which would have been vital for detecting the Titanic 's hull. Nonetheless, it surveyed an area of some 500 square nautical miles (1,700 square kilometres) and identified 14 possible targets. [23] A documentary of this expedition, featuring Welles, was titled Search for the Titanic (1981). [24] The Navy immediately relayed that information to on-scene commanders leading the search effort, and it was used to narrow down the area of the search, the official said Thursday. The two reciprocating engines were each 63 feet (19m) long and weighed 720 tons, with their bedplates contributing a further 195 tons. [30] They were powered by steam produced in 29 boilers, 24 of which were double-ended and five single-ended, which contained a total of 159 furnaces. [32] The boilers were 15feet 9inches (4.80m) in diameter and 20 feet (6.1m) long, each weighing 91.5 tons and capable of holding 48.5 tons of water. [33] The search had grown increasingly desperate on Thursday, when the submersible's estimated 96-hour air supply had been expected to run out if the Titan were still intact, a countdown that proved irrelevant.

OceanGate told CNN they have no information to share on this when reached for comment. CNN has also reached out to Canadian authorities for comment.

Before the Titanic expedition, Harding shared on Facebook that the mission was "likely to be the first and only manned mission to the Titanic in 2023" because of weather conditions. Estes, James A. (2006). Whales, Whaling, and Ocean Ecosystems. Los Angeles, CA: University of California Press. ISBN 978-0-520-24884-7. A friend of Nargeolet and fellow adventurer Alfred Hagan described him as a “wonderful warm human being” and a “incredibly talented iconic legendary – the greatest deep diver that the world has ever known.”

Nargeolet was described by Paschall as “someone that you instantly connected with and loved, and shared so many great stories with,” and his fascination with the underwater expedition of the Titanic intrigued him to share the stories of the past with people. Titanic 's owner J. P. Morgan was scheduled to travel on the maiden voyage but cancelled at the last minute. [119] Also aboard the ship were the White Star Line's managing director J. Bruce Ismay and Titanic 's designer Thomas Andrews†, who was on board to observe any problems and assess the general performance of the new ship. [120]
