A woman performing a wing-walking stunt and her pilot were killed on Saturday when their biplane crashed and burst into flames while doing aerobatics at an air show in Dayton, Reuters reported.

Veteran stuntwoman Jane Wicker and her pilot, Charlie Schwenker, died when their Boeing Stearman crashed around 1700 GMT at the Vectren Dayton Air Show.

Video footage of the incident replayed on television and the Internet showed that at the time of the crash, the duo appeared to have been executing a stunt in which the vintage plane flips as Wicker is out on one of its wings.

Once the aircraft turns upside down, Wicker maneuvers to sit on the bottom of the now-inverted wing. But in this case the plane smashed into a grassy area before Schwenker could pull out of the stunt.

No one on the ground was injured, organizers said.
