Controversy Surrounding Titanic Submarine Raises Questions About Safety and Cost.

NewsNation faced backlash from viewers for displaying a countdown clock for the remaining oxygen on the missing Titanic-bound Titan submersible during its round-the-clock coverage. Viewers called the chyron "insensitive" and "messed up." However, a NewsNation spokesperson defended the countdown clock, stating that it was an essential part of the story and that multiple media outlets had published or aired stories tracking the remaining oxygen. The U.S. Coast Guard confirmed that debris from the submersible was found on the ocean floor, indicating a "catastrophic implosion" that killed the five people aboard.
