NASA creates fire-fighting drone

NASA has developed a low-cost drone that can detect rising smoke plumes and help extinguish fires before they get out of control. Researchers at NASA Langley Research Center have turned a US Army target drone into a fire spotter.NASA Aerospace Engineer Mike Logan said he is hoping the idea will take off.‘The theory is that we should actually be able to see smoke rising up, or we should be able to see the hot spot with the infrared,’ said Logan, who heads the unmanned air vehicle laboratory at
NASA Langley.
