Book excerpt: Excerpt from Fire Control Notes, 1948, Vol. 9: A Periodical Devoted to the Technique of Forest Fire Control A1i Army Force Sikorsky model R - 5 was used for reconnaissance and a small amount of supply dropping on the Castaic fire in 1946. It did all that it was asked to do, but it worked under the tight wraps of the test conclusions. Nobody stepped out into the field of what can the damned thing do? The golden opportunity for a test of positive performance under trying field conditions came with the Bryant fire on August 5, 1947 This fire started in Big Tujunga Canyon Of the Angeles Forest, which is an area characterized by very high watershed values, considerable home investments, rapid rate Of fire spread, and steep, inaccessible country. Further, the fire was a direct threat to all of the suburban development on the north side Of Los Angeles. The Forest Service was not disposed to leave any possible resource unused. There were available the two Bell helicopters owned by the man who had partici pated in the earlier tests of the Bell and who was very much interested in proving the worth of the helicopter. These were pressed into service. Two Of the primary physical factors affecting the performance of helicopters which were encountered exceeded substantially the condi tions of the earlier test operations. Temperatures were up to 107 de grees as compared to the 100-degree temperatures under which the tests were conducted, and elevations were operated successfully up to feet as compared to the - foot elevation which was felt to be about the upper limit under the test conditions. Wind, a third important factor affecting the performance Of the machine, was, of course, vari able but generally exceeded the 0 to 5 miles employed under test conditions. With this set of conditions, and with two helicopters, two willing, skilled, and courageous pilots, and an experimentally minded fire manager, a fresh chapter in fire suppression history was written.
