Flying Fire Alarm Like the cavalry of old, a Los Angeles Police helicopter recently was credited with saving a dozen Hollywood homes from a brush fire. While on the freeway traffic patrol, Pilot Robert Van Aiken and Police Observer Dick Gillenberg noticed a plume of smoke from the Laurel Canyon area. As Van Aiken hovered over the blaze in the 8100 block of Gould Ave., the observer notified L. A. City firemen. Assistant Chief Forest W. Moore and five city fire units from the Hollywood area and Mountain Patrol arrived to save all of the homes. Meanwhile, one of the residents, Dorothy Gonzales, 8169 Gould, became curious at the noise of the whirlybird, went outside, saw the fire, and used a garden hose to save her own house.
