According to McCallim and other experts said that Rush had disregarded a series of safety warnings that they had raised.

He supposes that a recent graduate of Washington State University had told a student newspaper about his and his classmates' involvement in working on the electrical system of the Titan submersible.

Mark Walsh, who recently earned a degree in electrical engineering, said in a 2018 report at Washington State University that he and his classmates designed the electrical systems on Titan. "We designed the whole electrical system, we implemented it, and it worked," Walsh said.
According to the college newspaper, in 2019, Walsh graduated with a degree in electrical engineering. He then started as an intern at OceanGate and later transitioned to a full-time role as their electrical engineering lead.

The recent claim made by Walsh regarding the involvement of a team of interns in developing the electrical system for the Titan submersible is just one of many several bombshell revelations that have come to light regarding the inner workings of Rush's company.
However, Titan's electrical system which the Walsh intern team was unable to independently verify. Additionally, Representatives for OceanGate did not respond to this information.
Mr. Rush was also among those who passed away on the submarine.

Rush said the systems inside the Titan submersible operate via Bluetooth, but McCallum believes this is indeed a safety issue. "Every submarine in the world has fixed controls so that if the signal goes off, you don't die," he said.
Other experts who have worked on OceanGate, including skipper David Lochridge, who has since left the company over safety concerns, described the Titan as an "unsafe lemon" when driving.

Walsh's claim that the interns created Titan's electrical system and that McCallum had disturbing experiences in the workshop where they worked, is the latest in a string of explosive revelations surrounding the system.
Earlier, Rush's company claimed to have worked closely with NASA, Boeing, and the University of Washington on Titan's design, a claim denied by those groups.

On June 22, Washington State University clarified in a statement to the local newspaper, the Everett Herald, that they do not have any affiliation or alliance with OceanGate.
According to Insider, Corrie Wilder, Washington State University Everett's executive director of marketing and communications shared that:

"Our relationship with OceanGate was through WSU Everett graduates who were working for the company and who were interested in giving back to their alma mater by mentoring a senior capstone project".
The denials by stakeholders and the University of Washington have raised questions: Did OceanGate exaggerate and misrepresent its role in the design of the Titan submersible to lure wealthy clients to visit a Titan wreck they thought was safe?
