It was a suicide mission: Man who went on Titanic submarine two years ago

German adventurer Arthur Loibl undertook the trip to the Titanic wreckage in 2021 in the same submersible that has now gone missing with five people. "It was a suicide mission back then," he said. "Imagine a metal tube a few metres long with a sheet of metal for a floor. You can't stand. You can't kneel," he added.
