A Marine Corps refueling plane crashed and burned in a soybean field in the Mississippi Delta, killing all 16 military members aboard in a wreck that scattered debris for miles and sent a pillar of black smoke rising over the countryside.
It was the deadliest Marine crash — in the U.S. or abroad — since 2005.
Fifteen Marines and a Navy corpsman were on board the KC-130 tanker when it corkscrewed into the ground Monday afternoon about 85 miles (135 kilometers) north of Jackson, the state capital, military officials said. A witness said some bodies were found more than a mile away.
In a Tuesday morning tweet, President Donald Trump offered condolences.
"Marine Plane crash in Mississippi is heartbreaking. Melania and I send our deepest condolences to all!" Trump wrote.
The Marines gave no immediate details on the cause of the crash. The FBI joined the investigation, but Marine Corps Maj. Andrew Aranda told reporters no foul play was suspected.
The KC-130 is used to refuel aircraft in flight.
The flight originated from the Marine Corps Air Station Cherry Point, North Carolina, and was taking people and equipment to Naval Air Field El Centro, California, when it went down, officials said.
Some of the Marines were from a reserve squadron based in Newburgh, New York, the military said.
Andy Jones said he was working on his family's catfish farm just before 4 p.m. when he heard a boom and looked up to see the plane spiraling downward with one engine smoking.
"You looked up and you saw the plane twirling around," he said. "It was spinning down."
Jones said that by the time he and others reached the crash site, fires were burning too intensely to approach the wreckage. The force of the crash nearly flattened the plane, Jones said.
"Beans are about waist-high, and there wasn't much sticking out above the beans," he said.
Jones said a man borrowed his cellphone to report to authorities that there were bodies across a highway, more than a mile from the crash site.
Greenwood Fire Chief Marcus Banks told the Greenwood Commonwealth that debris was scattered in a radius of about 5 miles (8 kilometers).
Jones said firefighters tried to put out the fire but withdrew after an explosion forced them back. The fierce blaze produced black smoke visible for miles across the flat region and continued to burn after dusk, more than four hours later.
Marine Corps Air Station Cherry Point is about 115 miles (185 kilometers) southeast of Raleigh and about 20 miles (30 kilometers) from the Atlantic Ocean.
The station was authorized by Congress just before the start of World War II. It supports the 2nd Marine Aviation Wing, providing, among other services, KC-130 aircraft used for in-flight refueling. The station covers 45 square miles (115 square kilometers) and has nearly 14,000 Marines, sailors and civilian employees.
