Two people were tragically killed today at a Dayton-area air show when a plane carrying a wing walker crashed and burst into flames, WHIO-TV reports.

Dayton's director of aviation, Terrence Slaybaugh, confirmed that two people were hurt in the accident. "Obviously this is a tragedy for what is a very small community," he said.

Jane Wicker, a mother of two sons, was atop the biplane at the Vectren Air Show near Dayton, Ohio when it plunged to the ground in front of horrified onlookers. The pilot, Charlie Schwenker, also perished in the crash, according to the Daily Mail.

The Ohio State Highway Patrol is investigating along with the Federal Aviation Administration, which was already on scene for the show.

"Right now there is no conclusive answer about why the accident happened," Slaybaugh said. He said the investigation could take months.

Witnesses reported hearing screams as the plane dived to the ground.

'All of a sudden I heard screaming and looked up and there was a fire ball," Stan Thayer of Wilmington told the Dayton Daily News.

Shawn Warwick was also at the event and watching the crash through binoculars.
