DAYTON, Ohio (AP) — A stunt pilot won’t be able participate in this weekend’s Dayton air show after engine trouble forced him to land on an Ohio road.

Skip Stewart told the Dayton Daily News he was fine and his plane was undamaged after the emergency landing Thursday about 15 miles short of Dayton International Airport. But he’s grounded by the bad engine.

Other aerobatic pilots and military planes will be part of the annual Vectren Dayton Air Show at the airport Saturday and Sunday. The return of the U.S. Air Force Thunderbirds highlights the event.

Organizers say the 2018 show drew an estimated 62,000 people. The previous year, attendance fell to 44,000 when the Thunderbirds’ appearance was canceled after an accident that caused two Thunderbird team members to be hospitalized .
