SAGE Geographic Reorganization: The '''SAGE Geographic Reorganization Plan''' of July 25, 1958, by NORAD was "to provide a means for the orderly transition and phasing from [[Permanent System radar stations|the manual]] to the SAGE system."  The plan identified deactivation of the [[Eastern Air Defense Force|Eastern]], [[Central Air Defense Force|Central]], and [[Western Air Defense Force|Western Region/Defense Forces]] on July 1, 1960, and "current manual boundaries" were to be moved to the new "eight SAGE divisions" (1 in Canada, "the 35th") as soon as possible.  Manual divisions "not to get SAGE computers were to be phased out" along with their [[Manual Air Defense Control Center]]s at the headquarters base: "9th [at] [[Geiger Field]]… 32d, [[Syracuse AFS]]… 35th, [[Dobbins AFB]]… 58th, [[Wright-Patterson AFB]]… 85th, [[Andrews AFB]]".{{r|NORAD1958B}}  The 26th SAGE Division (New York, Boston, Syracuse & Bangor SAGE sectors)--the 1st of the SAGE divisions—became operational at [[Hancock Field Air National Guard Base|Hancock Field]] on 1 January 1959{{r|NORAD1958B}} after the redesignation started for [[List of United States Air Force aircraft control and warning squadrons|AC&W Squadrons]] (e.g., the [[Highlands Air Force Station|Highlands P-9]] unit became the [[646th Radar Squadron]] (SAGE) October 1.){{r|Johnson}}{{rp|156}}  Additional sectors included the [[Los Angeles Air Defense Sector]] (SAGE) designated in February 1959.

Part of the work ([[Project Broad Jump]]) was accomplished by [[Sacramento Air Materiel Area]]. The remainder ([[Project Wild Goose]]) was done at ADC bases by roving AMC field assistance teams supported by ADC maintenance personnel.
