A whistleblower previously voiced concerns over the safety of the missing Titanic submersible, court documents claim.
The 2018 documents reveal that an Oceangate employee raised issues about the safety and design of the vessel, named Titan.
Contact with the miniature sub, which has five people on board, was lost on Sunday as it made a 3,800m (12,467 ft) descent to the Titanic wreck.
