The Siebel Si 204 of the D-1 series with the master number DL + NT was an aircraft of the German Air Force that landed on May 7, 1945 in Bern-Belpmoos without a sovereign number. The machine was then interned and put back into service by the Swiss Air Force with registration B-3 . On May 7, 1945, it served the Grand Mufti of Jerusalem on his escape from Berlin via Klagenfurt to Switzerland. It was the only aircraft from the Siebel Flugzeugwerke in Halle that was ever acquired by the Swiss Air Force. After the decommissioning, the left engine, propeller and engine monitoring devices went into the inventory of the ETH Zurich .
history
The two-engine low - wing aircraft of the type Siebel Si 204 made of all metal landed in Switzerland shortly before the end of the Second World War and was interned there . In 1946 the aircraft was officially purchased by the Swiss Air Force. It did its job there in the field of material and pilot transport. During routine inspections in the summer of 1955, fatigue cracks appeared on the stern . The German manufacturer could not determine a maximum permissible service life. The responsible regulatory authority of the Air Force therefore decided to decommission the individual item.
The plane could carry up to eight passengers. It had a full view canopy, retractable landing gear, wheel brakes, blind flight, navigation and radio equipment and oxygen and fire extinguishing systems on board. The two-bladed propeller with a steel hub made of compressed wood was of the Argus L-22 Constant-Speed type. It had a diameter of 2.69 m and an adjustment range of 20 ° to 52 °.
internment
On May 5, 1945, the Swiss government ordered its envoy back from Berlin after it did not recognize the Dönitz government . The waning of the fighting activity on the northern border of Switzerland was related to the fact that the 1st French Army under General de Lattre Tassigny controlled the area around Lake Constance and quickly broke through towards the Allgäu, to the presumed Alpine fortress. The number of reported border violations, in this case overflights by third-party aircraft, was 650 in April. The number fell rapidly in May to 67 in total. On May 7, 1945, one day before Germany's capitulation , the Siebel landed in Bern-Belp with Mohammed Amin al-Husseini and two other passengers on board . Previously, al-Husseini had fled his residence in the capital of Berlin to Klagenfurt with 50,000 Reichsmark pocket money . The landing of this aircraft triggered an air raid alarm in Switzerland for the last time .
As early as May 9, 1945, the machine was transferred to Dübendorf with the now valid neutrality label. The Mufti was handed over to the French authorities as a persona non grata in Constance .
