BOSTON, June  20, 2023 (BSS/AFP) - A deep-diving tourist submersible that
went missing near the wreck of the Titanic with five people on board has "about
40 hours of breathable air" left, captain Jamie Frederick of the US Coast Guard
said Tuesday.
       
The air and ship rescue efforts near the site in the North Atlantic "have
not yielded any results," Frederick told reporters in Boston.
