LOS ANGELES (AP) _ Two small airplanes collided in the air Monday, sending one craft crashing and burning onto a golf course and the other into trees across a freeway. At least four people were killed.

Golfer Danny Garza said he ran for his life.

``All I hear is like an explosion, and as I look up I see this plane coming straight down and it looks like it got entangled in some telephone wires,'' Garza told KNBC-TV. ``And from then on I just kept running, thinking that these telephone wires were going to fall on me.''

Fire Capt. Steve Ruda said there were at least four dead, all from the planes. No one on the ground was hurt, authorities said.

The one plane hit on the seventh hole of Cascade Golf Course, in the Sylmar section of Los Angeles about 25 miles northwest of downtown. The other fell on the opposite side of Interstate 5, the main north-south route between northern and Southern California.

The area is in the approach to Van Nuys airport. Several shaken motorists pulled over to the side of the freeway. Several people on the golf course and the freeway called 911 for help.

Fire Department spokesman Bob Collis said they were searching for a body in nearby hills. ``Witnesses are saying that someone may have fallen out of one of the airplanes. Firefighters are trying to confirm that report,'' he said.

FAA operations officer Bruce Nelson confirmed two single-engine planes collided in the air. One was an experimental plane, the other was not immediately identified.
