On the morning of September 29, 1987, near Willits in Lake County, CA, five members of the Helitack crew on Copter 102 from Kneeland Helitack in Humboldt County, were removing vegetation in the path of a "spot fire" started by embers which were blown a short distance ahead of the main Lauder Fire. The larger fire suddenly roared in their direction and the smaller spot fire merged with it. All 5 crew members were entrapped and deployed their shelters. Denis Cullins died and the others suffered burn injuries covering 15 to 50 percent of their bodies.
