About 20 people have been injured in a charter plane crash near South Africa's capital, Pretoria.
Images showed a burning aircraft marked "Martin's Air Charter".
Social media photos showed the plane's fuselage broken, dented, and charred, amid a plume of smoke.
The Aviodrome aviation museum responded on Facebook to the crash as follows: "We are extremely shocked that the Convair 340, the aircraft that would soon come to Aviodrome, crashed during the takeoff of a test flight in South Africa".
At least twenty passengers have been pulled from the wreckage with paramedics, firefighters and police on the scene of the accident.
Tshwane emergency services' Johan Pieterse says four of the injured passengers were trapped in the wreck and they had to use specialised rescue equipment to free them.
ER24 later said on its Twitter feed that one fatality had since been reported from the scene, and that it had occured "in the cockpit".
The plane went down on Tuesday 10 July 2018, crashing into a small factory.
There is no information about how many people were on board the plane.
"All we know is shortly after take-off the plane experienced trouble and crashed".
Civil Aviation Authority (CAA) spokesperson Kabelo Ledwaba said their investigators were on their way to the crash.
