Tom Demi, an assistant fire chief at Coast Guard Fire and Rescue, ignites the pit before a simulated aircraft fire training evolution near Coast Guard Base Kodiak, May 23, 2013, in Kodiak, Alaska. Underwater pipes pumped fuel to the center of the fire pit, which served as the training ground for the aircraft emergency training exercises.
