Federal officials investigating Saturday’s plane crash at the Dayton Air Show say it may take up to a year before the cause of the crash can be determined.
An initial coroner’s report say that 44-year-old wing-walker Jane Wicker and the plane’s pilot, 64-year-old Charlie Schwenker, died of blunt force trauma.
The National Transportation Safety Board expects to release an initial report later this week. The NTSB is also requesting anyone with video or pictures of the crash to submit them to air show officials to help with the investigation.
Air show spokeswoman Brenda Kerfoot says while attendance was down in general, the crash didn't deter people on Sunday.
"I've heard many comments from families, etc, that said they wanted to leave on a positive note," she says. "Especially if they have children, they wanted them to know that this is a family event - that it's not normal what happened on Saturday."
Multiple Internet videos show the duo’s 450 HP Stearman biplane flying low and upside down before it turned and plunged to the ground, exploding into flames before thousands of spectators.
