The Ohio State Highway Patrol says "pilot error" is to blame for the fiery crash that left two people dead at last month's Dayton Air Show.
Wing Walker Jane Wicker and pilot Charles Schwenker were both killed when their 1941 Boeing Sterman glider plane crashed into the ground during a mid-day performance at the annual air show.
The FAA and NTSB are still investigating and will issue the final official cause at a later date.
