A WC-130 military plane crashed and burst into flames Wednesday shortly after takeoff at a Georgia airport, killing all five people aboard, the Georgia Air National Guard said.

The Puerto Rico Air National Guard plane crashed just before 11:30 a.m., shortly after takeoff from Savannah/Hilton Head International Airport, the Savannah Air National Guard said. The plane was bound for Davis-Monthan Air Force Base in Arizona and on a training mission when it went down.

“There has been a plane crash at the intersection of Hwy 21 at Crossgate Rd. Roads will be shut down. Please avoid the area,” Chatham EMA tweeted shortly after the incident.

Photos from the ground showed a section of the plane engulfed by fire and thick black smoke billowing to the sky. Only the tail section of the aircraft was intact.

Mark Jones told Savannah Morning News he was near the highway when he noticed a plane flying dangerously low.

“I could see [the plane] above the tree line and it looked kind of low like it was curving in toward street, but I see them all the time, so I didn’t think anything of it,” Jones said. “I looked down and then looked back up and it didn’t look like it nosedived, but it almost looked like it stalled and just went almost flat right there in the middle of the highway.”

Jones said he saw an explosion and believes the plane could have landed on cars driving on the road.

“There were definitely cars going both ways,” he said “…Most people stopped and got out of their cars.”

Firefighters put out the blaze but were still using a mixture of water and foam to take care of any remaining hot spots.

It’s unclear exactly what caused the crash. The Savannah Air National Guard said a board of officers will investigate the incident.

Savannah/Hilton Head International Airport said flights were being impacted by the plane crash and urged travelers to check with airlines regarding their flights.

A WC-130 is a weather reconnaissance aircraft used by the Air Force and Air National Guard. The planes usually have a crew of five people, according to the U.S. Air Force fact sheet.

The FAA initially identified the plane as a C-130 Hercules.
