The debris field found near the shipwreck of the Titanic is that of the missing Titan submersible that imploded, killing everyone on board.

It was found nearly 500-metres from the famous shipwreck.

Rear Admiral John Mauger of the U.S. Coast Guard says underwater sonar didn’t detect any catastrophic events in the last 72-ours, suggesting the implosion may have happened before underwater searching started.

He also says it’s not clear if bodies can be recovered.

The Coast Guard will continue searching the sea floor near the shipwreck for more clues about just what happened to the sub.

There’s no timeline for how long the international search will last.

The banging sounds heard recently were not from the sub.

The victims have been identified as OceanGate CEO and pilot Stockton Rush, Pakistani-British billionaire Shahzada Dawood and his 19-year-old son Suleman, British billionaire and explorer Hamish Harding, and Titanic expert Paul-Henry Nargeolet; who made several trips to the shipwreck.
