The flag outside the National Interagency Fire Center in Boise, Idaho, flies at half-staff July 10, 2012, in honor of the four crewmembers of MAFFS 7 who were killed when their MAFFS-equipped C-130 crashed during a fire fighting mission in South Dakota July 1. All Department of Agriculture and Department of Interior agencies flew their flags at half-staff to coincide with the crewmembers' memorial service held in Charlotte, N.C., that same day.
