Following the disappearance of the Titan submersible during a Titanic expedition, past passengers have voiced their experiences, with one individual describing the voyage as a "suicide mission." Arthur Loibl, a 61-year-old retired businessman, recounted his 2021 dive, highlighting the "extreme" nature of the journey. He mentioned technical difficulties, including a failed initial submarine and an aborted dive at 1,600 meters due to electrical problems. A five-hour delay ensued, and the stabilization tube's bracket had to be secured with zip ties, a detail Loibl claimed didn't faze him.

Loibl painted a stark picture of the conditions within the missing Titan, referring to it as "hell." He emphasized the need for strong nerves, the absence of claustrophobia, and the ability to endure ten hours in a cramped, cold environment with no seating or toilet facilities. The submersible, according to OceanGate's website, is approximately 22 feet long and 9.2 feet wide.

Another individual, Chris Brown, had also considered the $250,000 expedition, driven by a desire for adventure and exploration. However, he ultimately withdrew due to concerns about the technology and materials used. He refrained from elaborating on the specific safety issues that prompted his decision. A 2022 video interview revealed that OceanGate CEO Stockton Rush controlled the submersible using a modified video game controller.

Brown acknowledged that adventurers often overlook the impact their pursuits have on their families, who may not fully grasp the inherent risks involved. He expressed empathy for the loved ones of those on board the Titan, imagining the profound distress they must be experiencing.
