7 NC Marines killed after explosion during training

HAWTHORNE, Nev. (AP) — A mortar shell explosion killed seven Marines and injured a half-dozen more during mountain warfare training in Nevada’s high desert, prompting the Pentagon to immediately halt the use of the weapons until an investigation can determine their safety, officials said Tuesday.
The explosion occurred Monday night at the Hawthorne Army Depot, a facility used by troops heading overseas, during an exercise involving the 2nd Marine Expeditionary Force from Camp Lejeune. Several Marines from the unit were injured in the blast, authorities said.
The mortar round exploded in its firing tube during the exercise, said Brigadier General Jim Lukeman at a news conference at Camp Lejeune. He said investigators are trying to determine the cause of the malfunction.
The Pentagon expanded a temporary ban to prohibit the military from firing any 60mm mortar rounds until the results of the investigation. The Marine Corps said Tuesday a “blanket suspension” of 60mm mortars and associated firing tubes is in effect.
The Pentagon earlier had suspended use of all high-explosive and illumination mortar rounds that were in the same manufacturing lots as ones fired in Nevada
It was not immediately clear whether more than a single round exploded, a Marine Corps official said, speaking on condition of anonymity because the official wasn’t authorized to speak about an ongoing investigation.
Eight men under the age of 30 were taken to Renown Regional Medical Center in Reno with injuries, such as penetrating trauma, fractures and vascular injuries. One of them died, five were in serious condition, one in was fair condition and another was discharged, said spokesman Mark Earnest.
The identities of those killed won’t be released until 24 hours after their families are notified.
“We send our prayers and condolences to the families of Marines involved in this tragic incident,” said the force’s commander, Maj. Gen. Raymond C. Fox. “We mourn their loss, and it is with heavy hearts we remember their courage and sacrifice.”
The rescue was complicated by the remoteness of the site, which is favored because the harsh geography simulates conditions in Afghanistan.
The 60mm mortar is a weapon that traditionally requires three to four Marines to operate, but it’s common during training for others to observe nearby. The firing tube is supported in a tripod-like design and fires roughly a 3-pound shell, some 14 inches in length and a bit larger than 2 inches in diameter.
The mortar has changed little since World War II and remains one of the simplest weapons to operate, which is why it is found at the lowest level of infantry units, said Joseph Trevithick, a mortar expert with Global Security.org.
“Basically, it’s still a pipe and it’s got a firing pin at the bottom,” Trevithick said. Still, a number of things could go wrong from a fuse malfunctioning, a problem with the barrel’s assembly to a round prematurely detonating inside the tube, he said.
The Marine Corps official said an explosion at the point of firing in a training exercise could kill or maim anyone inside or nearby the protective mortar pit and could concussively detonate any mortars stored nearby in a phenomenon known as “sympathetic detonation.”
The official said a worldwide moratorium after such an accident is not unusual and would persist until the investigation determines that the weapon did not malfunction in ways that would hurt other Marines or that mortars manufactured at the same time as the one involved in the accident were safe.
The official said it would be normal to warn other U.S. military branches that use 60mm mortars, such as the Army, about the Marines warning. The moratorium could last for weeks or months.
The investigation will focus on whether the Marines followed procedures to properly fire the weapon, whether there was a malfunction in the firing device or in the explosive mortar itself, the official said.
The Hawthorne Army Depot stores and disposes of ammunition. The facility is made up of hundreds of buildings spread over more than 230 square miles, and bunkers dot the sagebrush-covered hills visible from the highway. Hawthorne is in the shadow of Mt. Baker, which reaches an elevation of 11,239 feet.

Thomasville mechanic killed when tractor-trailer falls on him
THOMASVILLE (AP) — Officials in Davidson County say a mechanic has died after a tractor-trailer he was repairing fell on him.
Larry James, interim director of the Davidson County Emergency Services, said 22-year-old Paul Peterson was pronounced dead at the scene.
James said Peterson was working under the front of a tractor-trailer when it fell on him and pinned him underneath late Monday afternoon. He said bystanders tried to get Peterson out from beneath the tractor-trailer, but were unable to free him.
James didn’t know what caused the tractor-trailer to fall. He said the N.C. Department of Labor was conducting an investigation into the accident.
