California Forestry Department Captain Daryll Pina says the Cobra attack helicopter crashed late Tuesday in the Cleveland National Forest.
Pina said Defense Department investigators were at the scene Wednesday morning.
Officials at Marine Corps Air Station Miramar said it was a Super Cobra helicopter from the 3rd Marine Aircraft Wing. The Marine Corps confirmed that both pilots were killed.
Pina said the crash started a one- to two-acre fire but the flames quickly burned out.
