FILE - In this Sept. 18, 2008, file photo, an air tanker drops fire retardant over a grass fire that threatened homes on the outskirts of Medford, Ore. Worried that the aircraft that drop huge plumes of pink fire retardant on wildfires may be getting too old for the job, a group of Western senators has asked for a review of the new U.S. Forest Service strategy for modernizing the fleet of privately owned planes and helicopters, many of them over 50 years old.
