In 1953, in cooperation with the USAF Wright-Air Development Center, Honeywell developed an automated control unit that could control an aircraft through various stages of a flight, from taxiing, to takeoff, to the point where the aircraft neared its destination and the pilot took over for landing. Called the Automatic Master Sequence Selector, the onboard control operated similarly to a player piano to relay instructions to the aircraft's autopilot at certain way points during the flight, significantly reducing the pilot's workload. Technologically, this effort had parallels to contemporary efforts in missile guidance and numerical control. Honeywell also developed the Wagtail missile with the USAF.
