escape fire
n.— «Wag Dodge, saw that it wasn’t going to work. So he stopped, took out some matches, and set the tall dry grass ahead of him on fire. The new blaze caught and rapidly spread up the slope. He stepped into the middle of the burned-out area it left behind, lay down, and called out to his crew to join him. He had invented what came to be called an “escape fire,” and it later became a standard part of Forest Service fire training.» —“The Bell Curve” by Atul Gawande New Yorker Nov. 29, 2004.
