“Within a few seconds the fire started, I ran out with extinguisher,” said Svard. “We got him out. We got his jacket off that was burning. Like I said, he’s just fine, but my extinguisher is no match for 20 gallons of fuel.”

Crews removed the man from the helicopter. They say he suffered minor burns in the incident.

Svard says the chopper is a Robbinson 22 and that his dad is a seasoned pilot.
