An interpretive sign that honors the Airmen of the North Carolina Air National Guard C-130 MAFFS-7 aircraft that crashed one year ago while supporting the White Draw Fire was dedicated July 1, 2013, near Edgemont, S.D. Four members of the six-person Modular Airborne Firefighting System 7 (MAFFS-7) aircrew died when strong winds out of a thunderstorm caused their air tanker to impact the ground on a ridge top northeast of Edgemont.
