“This a classic 1965 video describing the overall Airline tracking and reservation process, presented from the viewpoint of ATT (Bell Telephone). It includes not just the computerized reservation systems (such as IBM’s SABRE), but the telephone, teletype, radio, air traffic control and other aspects of how it all works together. A great vintage educational film. You may have seen this before, it is provided here with some improved audio and video. IBM and UNIVAC terminals are shown briefly in the film. Hope you enjoy.”
