Blast at a Tennessee explosives plant leaves 18 missing and feared dead, sheriff says

McEWEN, Tenn. (AP) — A blast leveled an explosives plant Friday in rural Tennessee, leaving behind a mass of twisted metal, burned-out shells of cars and at least 18 people missing and feared dead, authorities said.

“There’s nothing to describe. It’s gone,” Humphreys County Sheriff Chris Davis said of the blast site at Accurate Energetic Systems, which supplies and researches explosives for the military.

He said it was one of the worst scenes he’s ever seen and especially gut-wrenching because he knows three families connected to the tragedy. Davis said multiple people were killed, but he declined to say how many, referring to the 18 missing as “souls” because officials were still speaking to family.

Officials had originally said 19 people were missing, but Humphreys County Emergency Management Agency updated that number Friday night after they said one person believed to be on site was found safe at home.

The blast occurred at about 7:45 a.m., Davis said. Aerial footage showed the company's hilltop location smoldering and smoky. Debris was scattered over at least a half-mile area, and people more than 15 miles (24 kilometers) away felt the explosion, he said.

The company’s website says it processes explosives and ammunition at an eight-building facility that sprawls across wooded hills in the Bucksnort area, about 60 miles (97 kilometers) southwest of Nashville. It's not immediately known how many people worked at the plant or how many were there when the explosion happened.

Davis said investigators are trying to determine what happened and couldn't say what caused the explosion. Emergency crews were initially unable to enter the plant because of continuing detonations, said Hickman County Advanced EMT David Stewart.

By Friday afternoon, there was no further danger of explosions, and the scene was under control, said Grey Collier, a spokesperson for the Humphreys County Emergency Management Agency.

Accurate Energetic Systems, based in nearby McEwen, said in a post on social media that their “thoughts and prayers" are with the families and community impacted.

“We extend our gratitude to all first responders who continue to work tirelessly under difficult conditions,” the post said.

The company has been awarded numerous military contracts, largely by the U.S. Army and Navy, to supply different types of munitions and explosives, according to public records. The products ranged from bulk explosives to landmines and small breaching charges, including C4.

When the explosion occurred, residents in Lobelville, a 20-minute drive from the scene, said they felt their homes shake, and some people captured the loud boom of the explosion on their home cameras.

The blast rattled Gentry Stover from his sleep.

“I thought the house had collapsed with me inside of it,” he told The Associated Press. “I live very close to Accurate and I realized about 30 seconds after I woke up that it had to have been that.”

Tennessee Gov. Bill Lee posted on the social platform X that he is monitoring the situation and asked “Tennesseans to join us in prayer for the families impacted by this tragic incident.”

State Rep. Jody Barrett, from the neighboring town of Dickson, was worried about the possible economic impact because the plant is a key employer in the area.

“We absolutely heard it at the house,” Barrett said. “It sounded like something going through the roof of our house.”

A small group gathered for a vigil Friday night at a nearby park, clutching candles as they prayed for the missing and their families and sang “Amazing Grace."

The U.S. has a long history of deadly accidents at workplaces, including the Monongah coal mine explosion that killed 362 men and boys in West Virginia in 1907. Several high-profile industrial accidents in the 1960s helped lead President Richard Nixon to sign a law creating the Occupational Safety and Health Administration the next year.

In 2019, Accurate Energetic Systems faced several small fines from the U.S. Department of Labor for violations of policies meant to protect workers from exposure to hazardous chemicals, radiation and other irritants, according to citations from OSHA.

In 2014, an explosion occurred at another ammunition facility in the same small community, killing one person and injuring at least three others.

This story has been corrected to show officials say 18 people are missing, not 19, which officials originally reported.

CAPE CANAVERAL, Fla. (AP) — An ailing astronaut returned to Earth with three others on Thursday, ending their space station mission more than a month early in NASA’s first medical evacuation.

SpaceX guided the capsule to a middle-of-the-night splashdown in the Pacific near San Diego, less than 11 hours after the astronauts exited the International Space Station.

“It’s so good to be home,” said NASA astronaut Zena Cardman, the capsule commander.

It was an unexpected finish to a mission that began in August and left the orbiting lab with only one American and two Russians on board. NASA and SpaceX said they would try to move up the launch of a fresh crew of four; liftoff is currently targeted for mid-February.

Cardman and NASA’s Mike Fincke were joined on the return by Japan’s Kimiya Yui and Russia’s Oleg Platonov. Officials have refused to identify the astronaut who had the health problem or explain what happened, citing medical privacy.

While the astronaut was stable in orbit, NASA wanted them back on Earth as soon as possible to receive proper care and diagnostic testing. The entry and splashdown required no special changes or accommodations, officials said, and the recovery ship had its usual allotment of medical experts on board. It was not immediately known when the astronauts would fly from California to their home base in Houston. Platonov’s return to Moscow was also unclear.

NASA stressed repeatedly over the past week that this was not an emergency. The astronaut fell sick or was injured on Jan. 7, prompting NASA to call off the next day’s spacewalk by Cardman and Fincke, and ultimately resulting in the early return. It was the first time NASA cut short a spaceflight for medical reasons. The Russians had done so decades ago.

The space station has gotten by with three astronauts before, sometimes even with just two. NASA said it will be unable to perform a spacewalk, even for an emergency, until the arrival of the next crew, which has two Americans, one French and one Russian astronaut.
