Officials in California's San Bernardino County are tired of drones grounding their airborne firefighting efforts, that's why they've decided to take action. They're now offering a total of $75,000 in rewards to catch the pilots who flew their UAVs over three different forest fires -- they're allotting $25,000 in rewards for each one -- that took place these past months. During the latest one, which happened this mid-July, aerial firefighters reportedly came across five hobby drones flying over the affected areas that ultimately forced them to land. The 20-minute delay those drones caused was apparently enough for the flames to spread to the Interstate 15 freeway, burning cars in the process.
