In September 2019, the OceanGate team brought another of their submersibles,
Cyclops 1, to the Friday Harbor Labs to facilitate some deep-water research projects at the labs (and generate some publicity for OceanGate). I wasn't there at the time, but I did talk to two of the scientists who were involved. Both were very concerned at the cavalier attitude about safety that they observed from the OceanGate team, especially considering that they were diving in deep water in areas with very strong tidal currents. There seemed to be inadequate planning for technical failure or an unanticipated turn in the ocean conditions (e.g., an unanticipated uptick in the current). My friends both concluded that they wouldn't go out of their way to repeat the experience, regardless of the scientific opportunities.
Stockton Rush, founder and CEO of OceanGate and pilot of the crushed submersible, was part of the engineering team that designed and built the Titan submersible. He appears to have had substantial technical skills. As such, he would have been well-aware of the strengths and weaknesses of this craft. From transcripts of interviews that I have read over the last few days, he would NOT be characterized as cautious. At some level, that is fine if only his life was on the line. Adults are allowed to make risky choices (I fly fish; others use wingsuits or sky-dive...), especially if they are aware of the potential risks. But there is NO WAY that the paying passengers would be able to make their own assessment of risk. They were relying on Rush's assessment.
The situation with the Titan reminds of Jon Krakauer's book,
Into Thin Air which described a disaster among paid clients (and their for-profit guides) on Mount Everest that left eight climbers dead. In Krakauer's opinion (which is disputed by some), expedition leaders took chances and eroded their safety standards in the moment.
The whole situation is a tragedy and I grieve for the families.
