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 for frequency response, but decay effects as well. For instance, a damped sine wave can be modeled correctly using Laplace transforms. A function in the s-plane can be translated back into a function of time using the inverse Laplace transform where the real number formula_13 is chosen so the integration path is within the region of convergence of formula_8. However rather than use this complicated integral, most functions of interest are translated using tables of Laplace transform pairs, and the Cauchy residue theorem. Analysing the complex roots of an "s"-plane equation and plotting them on an Argand diagram can reveal
