The Region - News from Dec. 12, 1986

Forestry and fire officials planned today to set an experimental brush fire that has been delayed for three months--first by wind and rain and then by a helicopter crash last week. The fire was scheduled to be set in 1,000 acres of rugged chaparral in Angeles National Forest, 30 miles northwest of downtown Los Angeles. Data gathered during the four-hour fire will be used to study the “nuclear winter” theory, which predicts that smoke from fires ignited during a nuclear war would block sunlight and chill the earth.
