Mathias Rust Square was jokingly referred to by Muscovites as Sheremetyevo-3 (Sheremetyevo-1 and -2 being the two terminals at Moscow's main international airport). At the end of 1987, the police radio code used by law enforcement officers in Moscow was allegedly updated to include a code for an aircraft landing. Shortly after the incident, SubLogic, the original publishers of the "Flight Simulator" franchise, issued a scenery disk that expanded the original program's coverage area to include the Eastern Bloc. A challenge in the expansion pack was to land in Red Square as Rust had just done. Following the 20th anniversary of his
S-plane information about the frequency response and stability of a real time system. This process is called root locus analysis. S-plane In mathematics and engineering, the "s"-plane is the complex plane on which Laplace transforms are graphed. It is a mathematical domain where, instead of viewing processes in the time domain modeled with time-based functions, they are viewed as equations in the frequency domain. It is used as a graphical analysis tool in engineering and physics. A real function formula_1 in time formula_2 is translated into the "s"-plane by taking the integral of the function multiplied by formula_3 from formula_4 to
