The Park Fire is now the fifth largest wildfire in California history, growing to over 389,000 acres with 18 precent contained. The fire was started by arson on July 24 and grew to more than 70,000 acres in the first 24 hours. ⁠ ⁠ In this gallery, Cal Fire firefighters deploy a large Type 3 drone to drop incendiary devices to start fires in an effort to control and contain the Park Fire near Chico, California. The drone ejects Plastic Spherical Dispenser (PSD) balls, about the size of a pingpong ball, which ignite by chemical reaction to create fire when they hit the ground.
