Summary (Összefoglaló angolul)
Soviet —German co-operation contract signed in 1922 in Rapallo, and this made possible to transport Junkers F-13s to the Sovietunion. The aeroplanes mounted in Fili near Moscow and called Ju-13 ytpe. The soviet civil air traffic started between Moscow and Nisni-Novgorod by Ju-13 aeroplanes. In the country more air traffic companies were founded, but all operated Ju-13s on their lines. One of the Ju-13s in 1924 overflew in Afganistan the 7,000 metres high Hindukus mountains. In 1925 Kopilov pilot departing from Moscow flew 10,000 kilometres route and returned to the point of departure. On the course of extending the air traffic network in the Far-East, the F-13 aeroplanes got to Persia. In Persia founded Junkers Luftverkehr Persien company operated air traffic among many towns. K. Weil who stayed in the capital of Afganistan as a guest teacher, in 1969 found the wreckage of a F-13. The aeroplane was transported to München, where it was reconstructed and exhibited in the collection of the Deutsches Museum. This aeroplane was bought by afganian king Amanullah many years ago, during his visit in Germany. The F-13 entered into the history of Hungary too. In the summer of 1921 the Junkers Works delivered to the Ad Astra swiss aviation company one CH-59 registered land and one CH-66 registered water type aeroplanes for test, with the conditions that till the purchase of the planes they will serv for the training of the Ad Astra's pilots. W. Zimmermann had been sent to Switzerland as instructor-pilot, to be responsible for the aeroplanes till the purchase price not paid. The CH-59 registered (production number 574) aeroplane placed the Ad Astra company to the front pages of the international press. King IV. Károly who stayed in Switzerland, on 20th of October 1921, flew to Hungary by the CH-59 registered F-13 to assume the power from regent Horthy by military putsch. The aeroplane was hired form the Ad Astra company and the pilot Zimmermann was round to the plan. The royal couple, the secretary of the king and two hungrian airforce officers after some hours flying time landed at Dénesfa. The attemted putsch was defeated. King Károly and his companions were exiled to the island of Madeira by the Allies. The hungarian government destrined upon the aeroplane. Later the aeroplane was handed over to the Museum of Transport in Budapest. It could be seen in the collection today as well. This is the only perfect state aeroplane from the first serial production of the F-13, all over the world. On the fuselage CH-59 registration could be seen and on the wings CH-66, because the wings of the CH-59, which were destroyed in a hangar fire in Lugano, were replaced by the wings of CH-66 air-boat. When lifted the ban of flying which was ordered in the peace-treaty which was concluded after the first World War, at the end of 1922 became possible to establish airtransport companies on Hungary. This time was founded the Aeroexpress Corporation with 6 flying-boats which were stationed at the right bank of the river Danube in front of the Hotel Gellért. These planes were used for joy-rides over Budapest and the Lake Balaton. During the course of the joy-rides one of the aeroplanes crashed and one passanger died. In 1923 a famous flight was carried out because bishop Mikes travelled to Rome and back. This was the first instance, when an aeroplane of a hungarian airtransport company flew to abroad with passanger and also this was the first occassion that a prelate arrived to the Pope by aeroplane. The austrian OeLAG hired F-13 aeroplanes from the Aeroexpress which was in the frame of Transeuropa Union, to perform the air traffic between Vienna and Budapest. 6 S3
