TWO pilots were killed when an Indonesian military plane crashed in central Java at an air show, local media reported.

Video circulating on social media showed a fighter plane performing manoeuvres in the skies above Yogyakarta before spiralling toward the ground at speed and disappearing from view.

Seconds later a thick, dark plume of smoke rose beyond the horizon, as people in the video can be heard screaming.

The video footage at this stage has not been verified.

Indonesian air force spokesman Dwi Badarmanto confirmed a T-50 Golden Eagle fighter plane had crashed during a demonstration.

“Two pilots died,” he told news website Detik.
