The wreckage of the 22-foot submarine Titan washed ashore on a Canadian Coast Guard vessel on Wednesday, ending an episode of the fatal explosion that captivated global audiences last week.
Human remains may have been recovered from the sinking wreckage of the Titan, the US Coast Guard announced Wednesday night. Wrecked parts of the submarine have arrived in St. John’s, Newfoundland, and will be interrogated for important clues as to what caused the explosion that killed all five aboard.
The U.S. Coast Guard, which includes several government agencies in the U.S. and Canada, is investigating a “major marine casualty” during the submarine’s June 18 descent. According to the National Transportation Safety Board.
The pressure at the Titanic’s depths — 12,500 feet below — was almost 380 times that at the surface, and the Titan’s final moments would have been swift, experts in physics and submarines told USA TODAY.
Amid questions about whether Oceangate overstretched its ties to NASA, Boeing and the University of Washington in developing the Titan submarine, the Coast Guard said it wants to use the investigation to improve the safety of submersibles.
