ADELANTO, Calif. (AP) - Authorities say three people are dead after a vintage helicopter hit power lines, crashed and caught fire in San Bernardino County.

Federal Aviation Administration spokesman Ian Gregor says the Piasecki PV-18 took off from Adelanto Airport at 8:30 a.m. Saturday
headed for Flabob Airport in Riverside.

All three people aboard were killed when the helicopter crashed about a mile south of Adelanto Airport. Adelanto is a city in the Mojave Desert about 70 miles northeast of Los Angeles.

Investigators from the FAA and the National Transportation Safety Board were at the scene Saturday.

There was no immediate word on the cause and identities of the dead were not immediately released.

Gregor says the helicopter is a vintage military aircraft built in 1951.
