LOUISVILLE, Ky. (AP) — Emergency teams are set to continue their search for victims on Wednesday after a UPS cargo aircraft crashed and erupted into flames during takeoff from Louisville, Kentucky’s airport, which serves as the company’s central aviation hub. The tragic event resulted in the deaths of at least seven individuals and left 11 others injured, as reported by authorities.

The accident occurred around 5:15 p.m. on Tuesday as the plane was departing for Honolulu from UPS Worldport at Louisville Muhammad Ali International Airport.

Louisville Mayor Craig Greenberg noted that more than 200 responders were present at the site on Tuesday night. “We’re committed to deploying every resource at our disposal,” he assured WLKY-TV on Wednesday morning.

Footage captured flames engulfing the aircraft’s left wing and a thick smoke trail. Shortly after, the plane briefly lifted before plummeting and bursting into a massive fireball. The video also depicted a nearby building’s roof in tatters at the runway’s edge.

By Tuesday night, the confirmed death toll had climbed to at least seven, with four of the deceased not on board the aircraft, according to officials.

The death toll had risen to at least seven Tuesday night, and four of those killed were not on the plane, officials said.

Death toll could rise, Kentucky’s governor says

Kentucky Gov. Andy Beshear said he expects the death toll to increase. Eleven people were also hurt, some of whom had “very significant” injuries, he said.

“Anybody who has seen the images, the video, knows how violent this crash is,” he said.

Beshear said he didn’t know the status of the three crew members aboard the plane, a McDonnell Douglas MD-11 made in 1991.

UPS’s largest package handling facility is in Louisville and the company announced Tuesday night that it had halted package sorting at the center and didn’t say when it would resume. The hub employs thousands of workers, has 300 daily flights and sorts more than 400,000 packages an hour.

“We all know somebody who works at UPS,” Louisville Metro Council member Betsy Ruhe said. “And they’re all texting their friends, their family, trying to make sure everyone is safe. Sadly, some of those texts are probably going to go unanswered.”

Greenberg said the National Transportation Safety Board is handling the investigation and sending 28 people. He said city emergency management officials put together a form where nearby residents can report debris in their yards.

A shelter-in-place order that initially covered at least a 1-mile (1.6-kilometer) radius in the area was shrunk to just a quarter-mile (0.4-kilometer) radius early Wednesday as officials monitored the air quality, Greenberg said.

Airport is resuming operations after being shut down

The airport, meanwhile, shut down for the night. It began to resume operations Wednesday morning, with flights that were canceled Tuesday scheduled to depart and arrive first. Some flights previously scheduled to take off from the airport on Wednesday morning were canceled.

Some stranded passengers spent the night in the airport.

Some roads near the airport remained closed Wednesday and a public school district in Louisville canceled classes and activities for the day.

Pablo Rojas, an aviation attorney, said that based on the videos it looked like the aircraft was struggling to gain altitude as a fire blazed on its left side around one of its engines. Given the large amount of fuel it was carrying, once the fire started in that area, it would’ve been only a matter of time before there was an explosion or the fire grew rapidly.

“Really the plane itself is almost acting like a bomb because of the amount of fuel,” he said.

The governor said a business, Kentucky Petroleum Recycling, appeared to be “hit pretty directly,” and a nearby auto parts operation was also affected.

People gather seeking information about missing loved ones

Eric Richardson stood outside a police training academy where people gathered looking for information about missing loved ones Tuesday night, hoping to find out what had happened to his girlfriend. She had been at a metal recycling business near the explosion and wasn’t answering her phone, he told The Associated Press. Her phone’s live location said she was still there.

Bobby Whelan, Richardson’s friend, had been in front of her in line, but had left minutes before the explosion. He said he was about a quarter mile down the road when he heard what sounded like a bomb exploding.

“We don’t even want to think about anything but the best,” Whelan said. “All our friends were there.”

A video taken by Leirim Rodríguez shows several massive balls of flames exploding into the sky in a row, followed by large billowing clouds of black smoke.

Tom Brooks Jr., who runs a metal recycling business down the street, said the unbelievable magnitude of the crash “just rocked the whole place.”

“This was massive. I mean, it literally looked like a war zone,” he said.

Destyn Mitchell was working as a host at an Outback restaurant, about a 15-minute drive from the crash, when she heard a loud boom.

“The mood in the restaurant was very shaken up,” she said. “Everyone is really concerned. People who just sat down to eat got up and left in under 30 minutes and packed up their food because they wanted to hurry up and get home.”

The Louisville airport is only a 10-minute drive from the city’s downtown, which sits on the Ohio River bordering the Indiana state line. There are residential areas, a water park and museums in the area.
