“In 1935, the Forest Service established the so-called 10 a.m. policy, which decreed that every fire should be suppressed by 10 a.m. the day following its initial report. Other federal land management agencies quickly followed suit and joined the campaign to eliminate fire from the landscape. Fire suppression efforts were aided by the development of new technologies, such as airplanes, smokejumpers, and fire suppression chemicals. With such tools, fires could be fought anywhere—and were.”
