"Fracht West" building, which had been extended at short notice during construction to provide additional office space, was located somewhat off the main building. In the hangar area in the southwest, Heating Station II was put into operation and the Hangar II, which was designed for jet aircraft, was handed over to Swissair, shortly after the arrival of the Sud Aviation "Caravelle III" and the Douglas DC-8-32 in May 1960. Finally, in the summer of 1961, Swissair's in-flight catering service was given a new building between the head of the airport and the hangar area. The canton of Zürich acquired a further 135 hectares of land for the expansion of the civil engineering works, which lasted until the beginning of 1961 in parallel with the construction of the buildings. The apron areas were enlarged, particularly at the airport head and in the hangar area; the pier was also extended from 16 to 28 aircraft parking spaces, and buses were purchased to provide access to them. The west runway 10/28 was extended by 600 metres to the west, towards Rümlang, and opened on 1 January 1961 with its new operating length of 2500 metres. Blind runway 16/34 was extended 400 metres to the south in the direction of Opfikon and 700 metres to the north in the direction of Oberglatt. At its new operating length of 3700 m, it was released on 15 March 1961. By the time work was completed, the paved area at the airport covered 1,013,000 m2. Extension of the Terminal Building Although virtually all the buildings of the second phase had been completed by the end of 1961, the extension of the terminal building was still at the design stage. After the passenger terminal with two finger docks had failed in the cantonal referendum, the FIG had worked out a new project until 1958. This envisaged a two-storey transverse hall on the landside of the airport, on the two main floors of which arriving and departing passengers were functionally separated. For cost reasons, the federal government demanded a considerable redimensioning, which led to an open dispute about the preferred design. When the conflict, described by the media as a "war of experts", threatened to escalate, President Willy Spühler invited representatives of the Federation and the cantons to a conference on 9 December 1963. During the conference, FIG's airport planners and the canton of Zürich prevailed against the
