Unfortunately the US Forest Service terminated Aero Union's airtanker contract less than a year after this photo was taken, on 29 July 2011, due to alleged safety violations. All their magnificent P-3 Aerostar airtankers, including this former Spanish Orion (ex P.3-5), were withdrawn from use and stored at McClellan, Sacramento, CA.
