19 Firefighters Die Battling Arizona Wildfire

The Granite Mountain Hotshots “were hardworking, well-trained, experienced people,” Prescott's Fire Chief Dan Fraijo said.

They knew to pick escape routes and safety zones as they moved through the blazing forest, a lesson learned in the rigorous and repetitive training hotshot members undertake.

The Huffington Post reports that about 200 more firefighters arrived to the scorching mountains, doubling the number of firefighters battling the blaze, ignited by lightning.

Only one member of the 20-person crew survived, and that was because he was moving the unit's truck at the time.
