Two witnesses said they heard an explosion before a 1968 single-engine Cessna crashed in a field in Jennings County on Saturday night, killing a Versailles couple, Louisville television station WLKY reported.

"I was driving down the highway, going from Madison to a friend's house ... and I was talking actually to her on the phone and looked up in the sky and saw a big ball of fire," Becky Puckett said.

"(I) just saw it fall straight down and explode when it hit the ground," she told WLKY.

Jeremy Wade was indoors when he and the other people in the house heard an explosion.

"We (were) all watching a movie, and we heard a loud, I mean it wasn't maybe 20 seconds, the sound of a racing engine and then an explosion," he told WLKY.

Gregory Wehr and his wife, Candace, both 55, were on their way to Madison Municipal Airport from Chicago when the plane crashed. The Wehrs owned and operated the Greg Wehr Farm in Versailles, where they raised corn and soybeans.

The crash was near the Jennings-Jefferson county line. The crash was reported to Jennings County dispatch at 8:41 p.m.

Federal Aviation Administration officials arrived early Sunday to begin their investigation, but determining the cause might take weeks.
