Kelly Boyd, standing next to Kennedy on a bluff overlooking the blazing basin, smiles. He started that fire. Boyd piloted a drone that dropped balls of fiery chemicals, called Dragon Eggs, that ignited the “burnout operation.” The flames crawled down the basin, charring dry timber and foliage along the southeast edge of the 32,000-acre Grizzly Creek fire. That burned barrier connected two other containment lines, creating a barrier on the fire’s southern edge that prevented it from spreading any farther south.
