Federal Council. In addition to mandatory runway extensions for the incipient "jet age", the project also provided for the extension of the public facilities, which were already overused and dominated by various provisional arrangements; two finger docks were to defuse the situation. On 12 October 1956, the Federal Council recommended that parliament approve the bill. On 19 December 1956, the Council of States approved the federal contribution of CHF 54.8 million (at a total cost of 181.8 million), the National Council followed suit on 7 March 1957. The contribution of the canton of Zürich of CHF 74.3 million was still outstanding, the rest was to be raised by FIG and Swissair. The concrete expansion project included the extension of the blind runway to 4000 m and the western runway to 3150 m, as well as the extension of the buildings. Opponents described the "super airport Kloten" as a "luxury" and criticised that the canton had "lost every measure". Another issue that planners had completely neglected until then was the aircraft noise. With a high turnout of 72.3%, the expansion project failed in the cantonal referendum of 23 June 1957 with 97,603 votes to 83,196 (no vote of 54.0%). Just four days later, the Zürich's catonal government commissioned a redimensioned expansion project. The blind runway was to be only 3700 m long, the western runway 2500 m; the construction of the finger docks was abandoned. Thus the canton's share of the project to be approved was only CHF 49.1 million. The government gave far more attention to the aircraft noise. On 6 July 1958, voters approved the project by 107,050 votes to 56,872 (yes share 65.3%), with a 65.6% share. Due to time pressure - the landing of the first jet aircraft was planned for the following year - construction work began without waiting for approval of the federal funding. In December 1958 and March 1959 respectively, the National Council and the Council of States granted subsidies of 55.6 million. In 1959, BOAC started regular flight connections to Zürich with the revised "Comet IV", while the airport was still a construction site. The first buildings were completed in 1960, and the terminal building, which had been considered an attractive design, lost its symmetrical appearance. To the east, towards the former shanty town, office wing A1, office wing B and the air traffic control building were added with a connecting structure. The
