A single-engine Cessna 152 and a twin-engine Cessna 340 collided during their final decent, according to a statement from the Federal Aviation Administration. One person was on board the Cessna 152 and two people were on board the Cessna 340, the FAA said.
No one was injured on the ground, the FAA added. A pet on board one of the planes was also killed, Montesino said.
The city of Watsonville is about an hour south of San Jose.
“The City of Watsonville sends its deepest condolences to the friends and family of those who passed,” the statement said.
It is not clear what caused the two planes to collide.
