U.S. Air Force Lt. Col. John Casey, 47th Civil Engineer Squadron commander, uses a drip torch to spread a controlled burn at Laughlin Air Force Base, Texas, Jan. 13, 2024. Drip torches allow for precise control over where the fire starts, which is crucial for managing the burn's direction and spread. The criteria for initiating the burn were rigorously defined, encompassing factors like the moisture content in potential fuels, prevailing weather conditions, and the direction and velocity of the wind.
