Pieces of the sub that imploded while carrying five people exploring the Titanic wreckage have arrived back on land after being pulled from the sea floor. 

As time was running out on oxygen supply for those aboard the sub, the Coast Guard announced that debris was found about 1,600 feet from the bow of the Titanic at the bottom of the Atlantic. They determined that the debris was likely from the sub, which they said was “consistent with a catastrophic implosion of the vessel.”

The debris arrived in St. John’s, Newfoundland, on Wednesday (June 28), and footage showed a crane lifting it down to a crew of workers. Pelagic Research Services, the company that operated the  deep-sea robot that found the pieces, said in a statement that they had  completed “off-shore operations.”
