From Wired.com:
Earlier this month in Alaska, a 40-pound Insitu Scan Eagle saw duty fighting wildfires after dense haze grounded conventional aircraft. The UAV is operated by the University of Alaska, which according to university officials is the first entity other than NASA or the Department of Homeland Security allowed to fly an unmanned aircraft beyond the line of sight in civil airspace.
The Scan Eagle — which is Boeing’s best-selling aircraft right now — was able to fly low over the fires through the thick smoke. Infrared cameras allowed people on the ground tracking the fires to find hotspots and monitor the fire lines.
