Two Coast Guard Fire and Rescue attack teams combat a simulated aircraft fire during a training exercise near base Kodiak on 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.
