South of Kansas City is the former Richards-Gebaur AFB which from 1955-1970 was home to the 29th Air Division of the Air Defense Command. Based at "Dicky Goober" were F-102 Delta Dart interceptors but also a sector control of the ADC's integrated air defense system called SAGE (Semi-Automatic Ground Environment).
SAGE, built by IBM, was used to collect, organize, and disseminate information on the air defense environment of the continental United States for NORAD and the ADC.
The SAGE blockhouse was a four story windowless building that housed the massive computers of the day that SAGE used.

This AFB was the center of the Tactical Air Command, so this system was actually at the center of the system being deployed to coordinate air defense and warfare related to North America.
SAC, Tactical Air command command responsibilities were transferred to NORAD, and only the Omaha SAC base remained for some time. RGAFB was decommissioned and destroyed by bad planning by the Kansas City people who got control of the property.
