WILTON (CBS13) – Four people have suffered major injuries after their plane crashed in the Sacramento County town of Wilton.

The incident happened in the area of Alta Mesa and Blake roads, east of Elk Grove. The plane was reportedly a small cargo plane. Four people—a man, a pregnant woman and two teens—were badly injured in the crash. They were initially said to be in critical condition but are all expected to recover, according to the Sacramento Metro Fire Department.

One of the first people to witness the crash stopped their truck, got out a fire extinguisher, and helped the passengers to safety.

Steve Scharf jumped into action with a fire extinguisher to find the four survivors badly burned.

Scharf says the two teenagers and a pregnant woman were already out of the plane. He saw the man trying to escape.

“And then the guy that was life-flighted. I saw him like army-crawling out of the flames because his leg was broken,” Scharf said. “So I stopped him and had him just roll away, and sprayed him with my fire extinguisher.”

Scharf added, “The only thing that was going through my head is I wanted these people to be safe, and I wanted them to be alive, and I couldn’t sleep tonight if I watched a man burn right in front of me.”
