Mathias Rust considered as a domestic training plane defying regulations, and was issued least priority. Around 7:00 p.m. Rust appeared above Moscow. He had initially intended to land in the Kremlin, but he reasoned that landing inside, hidden by the Kremlin walls, would have allowed the KGB to arrest him and deny the incident. Therefore, he changed his landing spot to Red Square. Heavy pedestrian traffic did not allow him to land there either, so after circling about the square one more time, he was able to land on Bolshoy Moskvoretsky Bridge by St. Basil's Cathedral. A later inquiry found that trolleybus
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
