Families of sailors and Marines aboard the USS Abraham Lincoln are raising urgent concerns about deteriorating conditions on the aircraft carrier, which has now spent nine months at sea and five consecutive months in combat operations. The crew of more than 5,000 personnel is facing moldy showers, food shortages and a severe lack of basic supplies such as toothpaste, soap and deodorant, reported MS NOW. Most troubling to family members is the exhaustion plaguing the crew, who are working excruciatingly long shifts with minimal days off " a situation that military experts warn could lead to deadly mistakes on one of the world's most dangerous workplaces. "The morale is not good," said Bonnie York, whose stepson is on the Lincoln. "Apparently, the ship's doctor or therapist said they need to hit port soon or people are going to start, you know, losing their minds."
