Investigators picked through the gnarled wreckage Monday of two small planes that collided near an airport, killing five people — including one on the ground — and raining debris and bodies down on car dealership parking lots.

The two small Cessnas crashed at 3:35 p.m. Sunday about a mile from the small Corona Municipal Airport, authorities said.

Two people were killed from each plane, and a fifth was killed inside a Chevy dealership hit by wreckage, said Wayne Pollack of the National Transportation Safety Board.

"There were bodies falling out of the sky," eyewitness Hector Hernandez told KCBS-TV. "One of them crashed into the top of a Ford Mustang, and another one fell not too far behind that one on the parking lot."

The smashed fuselage of one of the planes landed atop a parked car. A wing from one of the planes sat in a parking lot. The debris was contained mostly within a 300-yard radius, said Pollack, although some pieces were found as far as 1,000 yards away.
