The Maneuvering Characteristics Augmentation System (MCAS) is a flight stabilizing feature developed by Boeing that became notorious for its role in two fatal accidents of the 737 MAX in 2018 and 2019, which killed all 346 passengers and crew among both flights.

Grumman F-14 Tomcat jet fighter during a takeoff, with stabilators deflected upwards. A stabilator is a fully movable aircraft horizontal stabilizer.It serves the usual functions of longitudinal stability, control and stick force requirements [1] otherwise performed by the separate parts of a conventional horizontal stabilizer (which is fixed) and elevator (which is adjustable).
An aircraft stabilizer is an aerodynamic surface, typically including one or more movable control surfaces, [1] [2] that provides longitudinal (pitch) and/or directional (yaw) stability and control. A stabilizer can feature a fixed or adjustable structure on which any movable control surfaces are hinged, or it can itself be a fully movable ...
5 position trim system. A variable-position horizontal stabilizer changes the pitch simultaneously with the flaperon setting. Normally the horizontal stabilizer also known as tailplane is fixed and has a hinged elevator, a stabilator is another method that combines the functions of an elevator and a horizontal stabilizer.
During the 1990s, a series of issues affecting the rudder of Boeing 737 passenger aircraft resulted in multiple incidents. In two separate accidents (United Airlines Flight 585 and USAir Flight 427), pilots lost control of their aircraft due to a sudden and unexpected rudder movement, and the resulting crashes killed everyone on board, 157 people in total.

The World War I transport USS Henderson, completed in 1917, was the first large ship with gyro stabilizers. It had two 25-ton, 9-foot (2.7 m) diameter flywheels mounted near the center of the ship, spun at 1100 rpm by 75 hp (56 kW) AC motors.
The aircraft involved was the prototype Boeing 747-400 (Boeing 747-451, c/n 23719, reg N661US) and was built by Boeing, and started the flight testing program for the new model, registered as N401PW, in April 1988.
