It was designed by famous German aircraft engineer Willy Messerschmitt."@en . "The Helwan-300 project was cancelled on May 1969. The real reason why it was cancelled remains a mystery but it can be inferred that the cancellation was due to many factors varying between technical, financial and political difficulties. The German engineers working on the design had to evacuate Egypt due to tensions with the Federal Republic of Germany, which led the development effort to stall. In order to fill the void created by the cancellation of this project, Egypt made close contacts with the Soviet Union and purchased aircraft instead of developing indigenous designs."@en .
