An autopsy report says the pilot of a vintage biplane that crashed during a Northern California air show died of burns.
The Air Force Wednesday says a Solano County autopsy report concluded extensive thermal injuries killed 77-year-old Eddie Andreini.
His plane crashed before 85,000 people during a May 4 show at Travis Air Force Base.
The plane was upside down and 20 feet off the ground for a stunt where a knife attached to it was supposed to cut a ribbon.
Instead, investigators say the plane struck the runway, slid and burst into flames before coming to a stop.
