A plane crashed at an Atlanta-area air show Saturday while performing stunts, killing the pilot, DeKalb County officials said.
The crash occurred at 4:49 p.m. at the DeKalb-Peachtree Airport north of Atlanta, where the 2016 Good Neighbor Day Airshow was being held, DeKalb County Public Information Officer Shiera Campbell said.
Juan Rios captured the crash on video. He told NBC News the accident happened during one of the last events of the afternoon.
Warning: The below video shows the crash and could be disturbing to some viewers.
The video shows two planes crossing each other close to the ground while trailing white smoke, before one of the planes rises high in the air in what appears to be a loop before descending and appearing to lose control.
"We were commenting about the amount of training that the pilots have to go through and then I started making the joke about the communication between the pilots," Rios said. "Then I just became speechless."
DeKalb Public Safety Director Cedric Alexander the jarring scene would be difficult for spectators to process. "There was a large crowd that was still here watching the air show when this occurred so we know this is going to be a very traumatic to a lot of people who witnessed this unfortunate event," he said.
The pilot will not be identified until next of kin is notified, Campbell said. Officials said he was from the Augusta area.
Authorities said the weather was clear at the time of the crash, and the cause is unclear. The National Transportation Safety Board will be investigating the crash and Federal Aviation Administration officials were at the scene Saturday, Campbell said.
The county said in a statement that the crash was the first accident in the 30 years that the Good Neighbor Day Air Show has been held.
Flags at the airport were flown at half-staff Saturday to honor the pilot who died, the county said.
