He said he ran to the burning house and saw a woman come out with singed hair.
The wounded were taken to a hospital with burn injuries, said Pokey Sanchez, an assistant chief with the Orange County Fire Authority. A firefighter was also treated for a minor injury.
Clint Langford, who lives about a half-mile away, said he was in his living room when he heard a low rumbling.
“It’s the eerie, low rumbling sound that keeps getting lower and louder. It was scary,” he said. “And then all of a sudden boom. It shook the house.”
He looked out his front door and could see plane parts falling out the sky in the distance.
Pat Rogers, who lives about a mile from the crash site, told the Orange County Register he saw the plane on fire and coming apart.
Video posted on Twitter showed panicked residents running to the house as it became engulfed in flames and dark smoke. One man doused a burning wing that landed on the street with a garden hose.
Aerial footage taken from news helicopters show plane parts, including side panels and a propeller, scattered on rooftops and driveways near the burned house. The main body of the twin-engine plane was found in the backyard of another home not far from the burned house. The fire spread to a SUV that was parked in the driveway.
