How many times did doomed Titan sub travel to the wreckage of the Titanic before disaster struck

OceanGate CEO Stockton Rush spent more than a decade seeking to perfect Titanic tourism – while battling multiple lawsuits and serious safety concerns.

Rush was one of five men who died on the Titan submersible after the vessel suffered a ‘catastrophic implosion’ 1,600ft from the bow of Titanic.

The frantic search and rescue attempt has since brought to light a host of flaws with the doomed vessel’s design and construction – with previous adventurers revealing how their own terrifying trips to the iconic wreck on the Titan went awry.

It is unclear exactly how many journeys the Titan submersible successfully made to the Titanic wreck, but it is thought to have carried passengers on at least ten trips before tragedy struck.

Rush, French Navy veteran Paul-Henri (PH) Nargeolet, British billionaire Hamish Harding, Pakistani businessman Shahzada Dawood and his son Suleman, 19, were instantly killed when the vessel malfunctioned on Sunday.

Here, DailyMail.com breaks down the timeline of events leading up to the Titan’s horrifying demise…

2009: OceanGate is founded

OceanGate was co-founded by Rush and Guillermo Söhnlein in 2009, starting operations on the West Coast.

Rush launched the company after graduating from Princeton University with a BSE in aerospace, aeronautical and astronautical engineering in 1984.

He obtained an MBA at the University of California Berkeley’s Haas School of Business in 1989, according to his biography on OceanGate’s website.

February 2012: OceanGate expands to Florida and the Caribbean  

The company registers as a corporation in Miami, with Söhnlein as president and Rush as secretary.

Documents state the company incorporated in Washington State in December 2011, but still considered itself Bahamas based.

May 2013: Collaboration announced with the University of Washington

OceanGate announced a collaboration with the University of Washington’s Applied Physics Lab on Project Cyclops, a new 3000-meter five-person submersible.

However the college has since denied working with the company on the Titan despite an initial press release. 

In a statement it said: ‘The physics lab initially signed a $5 million research collaborative agreement with OceanGate, but only $650,000 worth of work was completed before the two organizations parted ways.

‘That collaboration resulted in a steel-hulled vessel, named the Cyclops 1, that can travel to 500 meters depth, which is far shallower than the depths that OceanGate’s Titan submersible traveled to. 

‘The Laboratory was not involved in the design, engineering or testing of the Titan submersible used in the RMS Titanic expedition,’ 

August 2013: Submersible feasibility study into hull design

The University of Washington completed a design feasibility study for hull design for Cyclops submersible in August 2013.

Engineers handed over the vessel to the operations team – who renamed it the Titan.

March 2018: Trade group raises safety concerns

Leaders of the Manned Underwater Vehicles committee of the Marine Technology Society, sent a letter to OceanGate CEO Stockton Rush urging him to take caution.

The letter, obtained by the New York Times, warned that ‘the current ‘experimental’ approach’ of the company could result in problems ‘from minor to catastrophic.’

It was sent by the Manned Underwater Vehicles committee of the Marine Technology Society, a 60-year-old trade group that aims to promote ocean technology and educate the public about it.

But it is unclear if any employee or Rush himself responded to the letter, and there was no further detail on why the approach was considered dangerous.

The so-called 'adventure travel market' is the key target of OceanGate, Rush said previously. 'There's a huge demand for unique travel experiences,' he added

April 2018: Expedition canceled

Marc and Sharon Hagle said OceanGate canceled their June 2-9 expedition and rescheduled it to July 2019. Rush reassured them the trip would take place.

July 2018: Lawsuit lodged against former employee

OceanGate sued former Director of Marine operations for the Titan project, David Lochridge and his wife, Carole Reid Lochridge in Washington state.

They claimed Lochridge ‘desired to be fired’ and had shared confidential information with others and wiped a company hard drive.

The company said he ‘refused to accept the voracity of information’ about safety from Titan’s lead engineer.

August 2018: Lochridge files safety concern lawsuit

The Lochridges filed a counterclaim in the lawsuit, alleging a series of safety concerns about the Titan submersible.

Legal filings obtained by DailyMail.com show that he wrote a report in 2018 which was critical of the company’s research and development process for the vessel.

Lochridge also ‘strongly encouraged that OceanGate utilize a classification agency, such as the American Bureau of Shipping, to inspect and certify the Titan.’

The suit states that ‘OceanGate refused both requests, and stated it was unwilling to pay for a classification agency to inspect its experimental design.’

Lochridge ‘disagreed with OceanGate’s position to dive the submersible without any non-destructive testing to prove its integrity, and to subject passengers to potential extreme danger in an experimental submersible.’

OceanGate bosses fired David Lochridge, who was Director of Marine operations for the Titan project, in 2018 after it disagreed with his demand for more rigorous safety checks on the submersible, which is missing after a mission to the Titanic wreckage

February 2020: NASA to partner

NASA announced it would partner with OceanGate to develop and manufacture new carbon fiber pressure vessels at the Marshall Space Flight Center in Huntsville, Alabama,

Since the tragedy the agency has tried to distance itself from the company, saying it only carried out remote consultations with the company which built and deployed Titan, and ‘did not provide any approvals for the project’.

NASA told DailyMail.com it had a Space Act Agreement with OceanGate, which allows it to work with an outside organization, and ‘consulted on materials and manufacturing processes for the submersible’.

But a spokesman added: ‘NASA did not conduct testing and manufacturing via its workforce or facilities, which were done elsewhere by OceanGate.’

March 2021: NASA Astronaut joins expedition

OceanGate and NASA astronaut and physician Dr. Scott Parazynski announced he would join the Titanic expedition.

They had to abort the mission three-quarters of the way down, but Price was first to sign up for a second go the following day.

August 2021: German tourist brands Titan trip a ‘suicide mission’ 

Arthur Loibl, 60, called the voyage a ‘suicide mission’ after traveling down the ocean floor with the team in 2021.

Loibl recalls the first submarine they tried didn’t work and a second attempted dive had to be abandoned.

He said parts fell off and the mission went into the water five hours late due to electrical problems.

During his excursion the Titan took two-and-a-half hours to reach the bottom and then 20 minutes to reach the stricken ocean liner.

Speaking to AP he said: ‘The first submarine didn’t work, then a dive at 1,600 meters had to be abandoned.

‘My mission was the 5th, but we also went into the water five hours late due to electrical problems. It was a suicide mission back then!’

July  2022: Expedition encounters multiple difficulties 

CBS correspondent David Pogue said the submersible got ‘lost on the seafloor’ for about five hours when he was on an OceanGate expedition to the Titanic’s resting place.

He was not on the Titan, and had stayed on the ship in a control room, adding: ‘They could still send short texts to the sub, but did not know where it was. It was quiet and very tense.’

Colin Taylor went on the submersible with his 22-year-old son, and described the communication system as ‘very difficult.’

He told NBC news: ‘There’s a text-based communication system that’s two-way, very slow,’ he said. ‘I mean, when you’re sending signals through that amount of water, it’s very, very difficult.’

Simpsons producer and writer Mike Reiss told ABC News he went on four 10-hour dives with OceanGate, including to the Titanic.

He added: ‘The sonar, the computers, the lights all stopped working. We went back to the surface immediately.’

The crews lost communication with the host ship each time. According to their summary of 2022 they completed seven dives to the wreck.

YouTuber Alan Estrada had been on board the missing Titan sub when the batteries of the sub suddenly drained during the expedition, forcing it to end early. 

Estrada shared chilling details of how the Titan’s energy source quickly drained to 40 percent power during a July 2022 mission to see the ill-fated ocean liner. 

February 2023: Couple sue CEO Stockton Rush for fraud

A Florida couple sued the CEO of Titanic tourism company OceanGate Expeditions, accusing him of misleading them about their trip to visit the wreck and refusing to refund their $210,258 when they complained.

Marc and Sharon Hagle, sued Rush in Orange County, Florida circuit court, alleging fraudulent inducement and violation of Florida’s Deceptive and Unfair Trade Practices Act.

In 2016, while on a trip to the South Pole, they decided their next adventure would be underwater. 

But they never got to take their trip, and in February this year sued Rush, accusing him of selling the adventure knowing it was not on schedule, and refusing to refund their cash.

The Hagles claim Rush, a Princeton-educated engineer and pilot with a MBA from Berkeley, traveled to their home in Winter Park, a suburb of Orlando, Florida, to convince them to buy in to his company.

June 21, 2023: Search continues

Coast Guard reported a third C-130 was en route, as well as a Magellan ROV. The Navy was sending experts and a Deep Ocean Salvage System designed to lift underwater objects.

A team from France arrived to operate a remotely operated robot and a submarine deployed from the Atalante ship.

The boat can hold up to 30 technicians and scientists for up to 45 days, and both the devices on board are able to reach 6,000m (around 20,000ft) below sea level.

It has a manned submersible called Nautile and remote-operated vehicle Victor 6000 on board.

Nautile can dive to a depth of 20,000ft with a crew of three and is one of the very few manned deep-sea submarines.

It has three wide-angle viewports and LED searchlights provide a direct view of the seabed.

A dive on board the sub can last up to eight hours, of which six can be spent working at the sea floor.

The remote-operated Victor 600 is a deep-water ROV remotely operated by cable that can also go to depths of 20,000ft.

The Atalante - viewed as the final hope for the missing Titan sub - has arrived at the search site. It is dropping in a deep sea robot called the Victor 6000, shown at the stern of its mother vessel
