The military says five Air Force tankers are resuming firefighting flights after a deadly crash of one tanker over the weekend. U.S. Northern Command says the flights resume Tuesday. The entire fleet of eight planes was grounded after a C-130 crashed Sunday while fighting a wildfire in the Black Hills of South Dakota. The C-130 was from an Air National Guard wing based in Charlotte, N.C., and was carrying a crew of six. The crash killed at least two crew members and injured others.
