Doomed Titan Submersible Reportedly Contained 'Discount’ Parts 'Past Shelf Life'

The Titan submersible went missing on June 18, during an expedition to the Titanic wreckage in the North Atlantic, at a depth of approximately 13,000 feet. After the US Coast Guard confirmed days later that debris found on the ocean floor was made up of pieces of the missing sub, with all five passengers dead, an investigation was launched.
