Dry Conditions, a Breeze and a Drone Crash Start Fire in California Park

A hobbyist drone crash landed in a Sunnyvale, California, park Wednesday morning, sparking a grass fire.

The fire spread over a single acre and, according to KPIX-TV, was extinguished by the local fire department within 20 minutes of it starting.

Capt. Jeffrey Hunter with the city's public safety department told the news station dry conditions and a breeze allowed the fire to start and spread, likely caused by heat from the device itself or its battery.

Across the country, a separate but similar incident in East Hampton, New York, this week resulted in a drone-caused sidewalk fire.

According to the Sag Harbor Express, photographer Paul Callahan was taking aerial photos of a local condominium building Tuesday when the device "just went out of control," he said.

The drone hit a boy in the leg, though he was not seriously injured, and caused some minor damage to a variety store. The destroyed drone was extinguished by firefighters.

Callahan told the Express, which noted another drone mishap of his involving a sailboat, that his career as a drone pilot was over.
