Investigators looking into the Titan sub disaster say finding answers is 'complex' and will take longer than expected

• OceanGate's Titan submersible imploded a year ago, killing all five on board.
• The investigation into the implosion is dragging on and will miss the 12-month deadline.
• There's currently no projected completion date for the investigation, the US Coast Guard told BI.

On June 18, 2023, OceanGate's Titan submersible imploded while heading to the wreckage of the Titanic. All five on board died.

A year later, investigators say that finding answers to what happened is "complex" and will take longer than anticipated.
