Episode notes
Early Warning Focused On Bomber Threats
- Early NORAD planning focused on nuclear-armed bomber threats because intelligence gaps made ICBM timelines uncertain.
- Command expected little warning, so sensors aimed to detect a single bomber that could destroy a city and keep forces on base ready to respond within hours.
SAGE Invented Modern Command And Control Tools
- 1950s SAGE computerized continental-scale radar data into building-sized computers to link sensors to fighters and missiles.
- SAGE pioneered modems, light-pen interaction (mouse precursor), and automated fighter control including nuclear-armed Genie rockets.
SAGE Gave Birth To Modern Airline Reservations
- SAGE development led to civilian spinouts like the Sabre travel reservation system used by airlines.
- Lincoln Lab engineers solved reservation databasing by adapting SAGE's real-time shared-state capabilities for commercial use.
