Two members of Coast Guard Fire and Rescue battle a simulated aircraft fire at the training pit adjacent to Coast Guard Base Kodiak May 23, 2013, in Kodiak, Alaska. These controlled pit fire exercises give the firefighter an understanding of the intensity and dynamics involved in an actual aircraft fire emergency, and train them in the proper methods to combating such fires.
