Newport Beach, California – Tuesday, a helicopter crashed into a house in a Newport Beach, California, leaving at least three people dead and two others injured, according to the Newport Fire Department. Fire Chief Chip Duncan confirmed the fatalities.

According to reports, one of the deceased was a person on the ground.

Newport Beach Police said four people were believed to be onboard when it went down.

Residents of the home that was struck were inside the home at the time of the crash, police say none of the residents appeared to be hurt.

Two people were rushed to the hospital. Currently, their conditions are unclear.

A witness said he saw the chopper “drop like a rock.” He also mentioned that he allegedly saw the pilot lying injured — but alive — on the grass. It is unclear if it was indeed the pilot. The helicopter is reportedly a Robinson R44 owned by Revolution Aviation.

Revolution Aviation has been offering pilot training and sightseeing trips since the 1960s. The company’s website claims to have a 100 percent safety record.

Marian Michaels, who lives behind the house that was struck by the chopper, told The Associated Press her house shook when the crash happened.

“There was no fire,” she told AP. “It looked like they were trying to land in the street but clipped the roof across the street and didn’t make it.”

The house that was hit was for sale and she saw the owners talking to firefighters.

The incident happened just before 2 p.m. local time about a mile away from John Wayne Airport in Orange County where the helicopter had taken off, according to FAA spokesman Ian Gregor.

Newport Beach is about 45 miles southeast of Los Angeles.

The FAA and NTSB will handle the case. The reason for the crash remains under investigation.
