Two private planes collided over suburban Los Angeles on Sunday at about a mile from the airport, killing five people, according to authorities.

Around 3:35 p.m. the two Cessnas collided in Corona, California, 40 miles from downtown Los Angeles, and north of Riverside freeway, according to Federal Aviation Administration spokesman Allen Kenitzer.

Each plane carried a passenger and both passengers and pilots were killed. National Transportation Safety Board investigator Wayne Pollack said that one person inside a car dealership was killed by the wreckage.

Still the death toll is not yet final until Monday when one of the planes will be opened and the bodies will be removed.  

Pollack said: “Until we open that aircraft up we cannot be certain how many people were on board.”

According to CNN, the two planes were Cessnas with single engine, one was a Cessna 150 with two seats, and the other one was Cessna 172 with four seats.

The debris from the crash spread over an area of hundreds yards in riverside County and witnesses who saw the collision called 911.

The engine from Cessna 150 fell on the roof of a dealership and killed a person inside the building.

One eyewitness, Jeff Hardin, said: "The smaller aircraft ... just disintegrated into pieces, maybe fifty pieces coming down. The other aircraft pretty much stayed intact and started spiraling down and came down right behind the Nissan dealer," the Associated Press reports.

He added: "There were maybe 50 pieces coming down."

According to aircraft databases, the Cessna 172 is registered to William A. Reinke of La Habra, California.

The Cessna 150 is registered on Air Corona, Inc., with base in Dover Delaware.

Federal Aviation Administration didn’t have the flight plan yet so the destination of the two planes was unknown.
