A small plane flying from Florida to Oxford, Mississippi, crashed while attempting to land in Alabama on Sunday, leaving six people dead. The pilot issued a distress signal over engine problems around 11 a.m., and the plane went down shortly after, falling short of a runway at Tuscaloosa Regional Airport, authorities said. Firefighters rushed to the scene but were unable to save anyone on board. “They did everything they could,” Northport Mayor Bobby Herndon said at a news conference about the accident. Three married couples were on board and were returning from a dental conference in Kissimmee, and are reported to have left 11 children behind.
