Some say aerial fire-fighting is too dangerous to do at night. But at night-time fires burn slower with slower winds and lower temperatures, a perfect time to knock down a fire. Of course, aerial fire-fighting pilots tell of how hard it is to see using night-vision goggles and when flying through smoke in zero-zero visibility. Proponents of aerial fire-fighting say we need to use GPS-GIS advanced technology, perhaps, even send up UAVs (drones) to do the fire-fighting by air.
