UPDATE: Two Injured in Plane Incident at Owen Sound Airport

Ontario Provincial Police say two people have been hurt in an incident at Owen Sound Billy Bishop Regional Airport.

Investigators are trying to determine how a vintage plane overturned during a fundraising event at the airport around 2:30 Sunday afternoon.

The plane is a World War II Harvard Mark4.    Police say the plane was attempting a landing when it somehow went off the runway and flipped onto the grass.

Two people, a 46-year-old man from Toronto who was the pilot, and his 21-year-old female passenger, from West Grey, suffered minor injuries.   The pilot was taken to hospital where he was treated and released.   The passenger was treated at the scene.   An off-duty doctor and a nurse attending the event came to the victims’ aid, police say.

The airfield was hosting the Wings and Wheels fundraiser, where over 300 vehicles and 60 planes were on display.

The Transportation Safety Board has been notified and will continue the investigation.
