The debris field suggests that the missing sub suffered a "catastrophic implosion," the Coast Guard said.
BOSTON – Debris found near the Titanic on Thursday indicates the missing submersible that was on a voyage to explore the wreckage suffered a “catastrophic implosion,” the Coast Guard said, killing all five people on board.
A Canadian research vessel lost contact with the 21-foot sub an hour and 45 minutes into its dive Sunday morning about 900 nautical miles off the coast of Cape Cod. It had been expected to resurface Sunday afternoon.
