Dan Griswold, a captain at Coast Guard Fire and Rescue, observes an attack team combating a simulated out of control aircraft fire near 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.
