Airline dispatchers at Seattle-Tacoma Airport use a newly developed push-button public address system for announcing incoming and outgoing flights. Each flight announcement, coded by letter and number, is listed in a small remote control box at each of the eight gates. When the airline agents meets a flight, he pushes two buttons on the box, releasing the proper recorded announcement over the public loudspeakers. Heart of the system is a 100-selection Seeburg player. One announcement is cut on each side of a 10-inch disk. At present 60 records are used to cover the arrivals of UAL, WAL and NWA. It is stated that the new device will save $1400 monthly over comparable systems employing the services of live operators.
