The saga of the Titan submersible gripped the country for days this month. It was remote in a physical sense — a capsule lost somewhere in the middle of the ocean. It was also remote in an experiential sense — only a tiny number of people have ever done anything like that. But among that tiny number is journalist David Pogue, who went on an OceanGate expedition to the Titanic wreck last summer for a CBS News segment. (Well, Pogue didn’t actually make it down to the wreck because of a technical snafu he describes in this piece, but he did otherwise go through the full process.) In this journal-style recounting of his experiences and impressions during the nine-day trip, he grapples with being on OceanGate’s penultimate voyage prior to this month’s catastrophe and tries to figure out if there were clear warning signs — especially from Stockton Rush, company founder and designer of the craft. (Rush was, of course, killed along with three paying passengers and a crew member when Titan imploded.) The answer Pogue arrives at is complicated but convincing.
