SAN DIEGO: Two small planes collided midair while approaching an airport in San Diego County on Sunday, killing at least four people and sparking brush fires in a remote field where the wreckage landed, authorities said.
The collision occurred at about 11 am, Federal Aviation Administration spokesman Ian Gregor said.
Both planes a twin-engine Sabreliner jet and a single-engine Cessna 172 were approaching Brown Field, Gregor said.
The aircraft caught fire when they hit the ground and broke apart, said Nick Schuler, a division chief with the California Department of Forestry and Fire Protection.
First responders initially reported three fatalities, but as they inspected the wreckage which was strewn across a quarter-mile area, they determined that at least four people were killed, he said.
The Sabreliner crashed on a grassy slope and the Cessna fell within the bounds of the San Diego National Wildlife Refuge.
Crews extinguished several brush fires where the planes came down. One firefighter was taken to the hospital after he suffered a heat-related injury, Schuler said.
Brown Field, a former naval auxiliary air station, is in the Otay Mesa area southeast of downtown San Diego, near the border with Mexico.
The FAA and National Transportation Safety Board will investigate, Gregor said.
