A single-engine plane struck the roof of a building in Southern California, sending one person to the hospital.

The Piper PA-28 went down under unknown circumstances Sunday afternoon and ended up on top of a state parole building in Pomona, east of Los Angeles.

Two people were aboard the plane and one of them was taken to the hospital as a precaution, said Melanie Flores, a supervising dispatcher with the Los Angeles County Fire Department.

An aerial shot broadcast on KNBC-TV showed the nose of the plane punching a hole through the roof. There was no sign of smoke or fire.

According to the news station, the pilot told fire officials that the plane lost power and witnesses reported seeing it glide down to the roof of the one-story building.

The Federal Aviation Administration said the plane was heading to Brackett Field Airport in the nearby city of La Verne when it crashed.
