Forest Service employees Steve Christman, right, and Griff Williams, both of Enterprise, loaded incendiary Ping-Pong balls into a machine last week at the Baker City Municipal Airport. The machine, which is mounted in the helicopter, shoots the balls, which ignite after 20 seconds. The Forest Service uses the machine to light prescribed fires. The machine does the job faster than people walking on the ground with drip torches. (Baker City Herald
