"Nikolai you are mentally retarded" my mother said, ha but i showed her! I Nikolai Ibrahamovic Guverich am a greatest aircraft disigner of all Ukraine!! They laughed at the academy "A two stroke engine fueled with leaded Kerosene, impossible!" they said. "A jewish aircraft designer", impossibe they said. I showed them! By defecting and selling my plane to the Americans "The name of your plane acronymed is offensive" they said. I sold it anyway and i showed the world that nothing is impossible! P.S . Nothing is impossible except keeping this machine flying, at about 300 meters it begins to yaw and pitch like an inibriated goat, the engine begins to flutter and the thing turns into a meteor. But 200 dollars is 200 dollars.
