The Dübendorf military airfield ( ICAO code LSMD ) is located in the area of ​​the Swiss city ​​of Dübendorf of the same name and the communities of Volketswil and Wangen-Brüttisellen northeast of the city of Zurich . It is used by helicopters, fixed-wing aircraft and special aircraft of the Swiss Air Force , but no longer by fighter jets , and houses the operational management of the Swiss Air Force.

The airfield, which was built for civilian purposes in 1910, is used for civil and military purposes in accordance with the Federal Council 's concept of September 3, 2014. The federal government commissioned Flugplatz Dübendorf AG to organize the operation of a future civil airfield. These civil aviation plans of the federal government are being opposed by the region and the canton of Zurich. The local communities of Dübendorf, Volketswil and Wangen-Brüttisellen are jointly campaigning for a concept of a historic airfield with works flights, which limits the number of flight movements and in particular dispenses with small-scale and sport aviation and flights outside office hours. The voters of the three municipalities approved this concept on November 26, 2017 with a large majority. A "national innovation park" will be set up on an area of ​​71 hectares.

history

Early mixed use years

Aircraft squadron in the First World War

In 1909, the French aviator Reynold Jaboulin, while looking for a suitable starting point for his demonstration flights with a "flying machine", found the plain between Wangen and Dübendorf , at that time still pristine reedland with reed ponds.

On March 14, 1910, a lease for the construction of a civil airfield was signed. In August 1910, started improvement works under Jaboulins line, and on October 1, 1910, the "cooperative Aerodrom Dübendorf» was founded. On October 22nd, 1910, a big flight festival was celebrated in Dübendorf. This after initial confusion about the final location of the airfield, because in the meantime the Swiss Airfield Society (SFG) had been offered dry, immediately operational terrain in the area of ​​the Aargau municipality of Spreitenbach at much cheaper conditions. On September 28, 1910, the company had decided not to enter into the contract with Dübendorf. At the general assembly of the SFG on February 20, 1911, it was decided to enter into the lease agreement with the Oberried-Dübendorf cooperative.

In 1912 the money ran out and hangars became barns. In 1914 the federal government chose Dübendorf as the location for a military airfield. The site was initially leased. On November 27, 1918, the federal government bought the entire area for 380,000  francs .

After the First World War, local air traffic began from Zurich- Schwamendingen and from the seaplane station on the Zurichhorn . Later Dübendorf was declared the main airfield, from where international passenger flights were also started.

Dübendorf became the cradle of Swiss aviation, both in civil aviation and in military terms. Parts of the Swiss Air Force (now the Air Force ) have been active here since 1914. Aviation pioneers such as Oskar Bider , who had a fatal accident here, Alfred Comte , Walter Mittelholzer , one of the co-founders of Swissair , used the airfield for their flying activities. On August 18, 1932, Auguste Piccard and the Belgian physicist Max Cosyns (1906-1998) rose from Dübendorf for the second time in a gas balloon . They set a new world record with 16,940 meters ( geometric measurement , barometric 16,201 meters).

New communication technologies were used early on at Dübendorf airfield. The radio technology was used here for air traffic control and was used for both civil aviation and the military. The first radio station went into operation as early as 1919. For international flight operations from 1922 onwards, extensions were carried out. On June 1, 1922, Henry Pillichody opened the first Swiss civil air service: With a four-seater Junkers J 13 of the Ad Astra Aero , he offered a scheduled double route Geneva - Dübendorf - Fürth / Nuremberg and back. Since commercial flight operations require a means of communication that is faster than the aircraft itself, the Dübendorf / Kloten radio station has also been used for civil air traffic since then.

On September 14, 1930, the Zurich electorate rejected a loan of CHF 3.5 million for the construction of high-rise buildings on the airfield. The Federal Aviation Office then made two demands for a first-class customs airport , which must be met by May 1, 1931: the construction of a terminal building with all technical and service facilities and, secondly, the construction of a hangar for two large aircraft with a 40-meter gate width and a further hangar for commercial use Traffic. The government council then submitted a draft which provided for the construction of the large hall for an amount of 500,000 francs within the competence of the cantonal council. The concentration of the aircraft maintenance of the newly founded Swissair with up to 70 mechanics had also failed due to the unfortunate circumstances in Dübendorf, which is why Basel had offered to build a heated hangar. On May 22, 1931, the founding meeting for a cooperative took place, which comprised numerous interest groups and associations. The goal was a "simple but expandable system that would be sufficient for a few years". On study trips, plants in Stuttgart were visited as well as the "imposing" plant in Munich, which was not in question. The construction project of the company Kündig and Dietiker was changed and recalculated several times: The private but not profit-oriented company was to build the buildings on a private basis for the civil engineering structures to be built by the canton. The buildings would then have to be rented by the canton as the operator of the airfield with a right of reversion . In any case, the previous company premises had to be cleared by January 1, 1932 by order of the military airfield.

Arrival of travelers in 1937

The Swissair between 1932 and 1948, its predecessor Ad Astra Aero from 1919 located in Dübendorf. In 1932 the new terminal building was opened on the civil side of the airfield area. In this protected building, a wall mosaic with the Swissair route network at the time has been preserved. A film made in 1939 with the title “The most beautiful day of my life” provided information about flight operations in Dübendorf and the development of Swissair.

The following types of aircraft were used by Swissair from Dübendorf:

Following the precautionary termination of the joint use of the airfield by the federal government in 1939, the canton of Zurich decided in 1943 to build a purely civil airfield in Kloten . Swissair's move from its home airport at Dübendorf-Wangen to the newly created intercontinental Zurich-Kloten airport began in June 1948 with the opening of the western runway and was completed with the opening of the blind runway in November 1948. On April 30, 1949, the fleet of the Zurich Motorfluggruppe was relocated from the former sports aircraft hangar to Kloten in a relay flight. After the remaining technical departments of Swissair had also been relocated to Kloten at the end of April 1949, the airfield, which had previously been used for mixed aviation, became a purely military airfield .

Military airfield of the Swiss Air Force

Much has changed since Captain Theodor Real arrived at the airfield in 1914 with his air force , some of whose pilots brought their private aircraft with them. The aircraft, in particular, have been continuously developed: the fragile “boxes” of the early days became highly motorized and agile fighter planes. The “Häfelis” , “Dewoitines” and “Fokkers” were followed by the “Moranes” , “Messerschmitts” and “Mustangs” . With the “Vampires” and a little later the “Venoms” followed the first jet-powered fighter planes. The successors were the Hawker Hunter , who enjoyed high publicity among the public through their work with the Patrouille Suisse . The latter was stationed at the airfield from its establishment on August 22, 1964 until 1994. The acquisition of the Mirage III S and Mirage III RS was connected with the Mirage affair .

At the same time, the infrastructure of the airfield was continuously developed and expanded. The runway system was adapted to meet contemporary requirements with an extension to effectively 2750 m and a high-quality instrument landing system (ILS) was installed, which allows landings even in poor visibility. The Dübendorf military airfield was also the main base of operations for the military helicopter rescue service . According to the LENK movement statistics, the peak of activities was achieved in 1985 with a total of 46,484 flight movements, of which 31,174 were jet flight movements by Mirages, Tigers, Hunters and Vampires.

"The Dübendorf military airfield is the second most important airfield for our air force."

- Adolf Ogi , Head of VBS (2000)

The surveillance squadron (UeG) was stationed in Dübendorf in the former Swissair terminal from its establishment in 1941 until its dissolution on December 31, 2005 . The UeG's staff was transferred to the newly formed professional aviation corps . The aerial reconnaissance was also stationed in Dübendorf and flew with the Mirage III RS from Dübendorf until December 18, 2003 .

The airfield was at the end of the jet-flying, in particular from the Squadron 11 with fighter aircraft of the type McDonnell Douglas F / A-18 used by 16 December of 2005. The safety cable system for F / A-18 and F-5, which was present at both ends of the runway and was removed in 2005, could be lowered flush with the runway so that it was not an obstacle for small aircraft.

As part of a new deployment concept for the Swiss Armed Forces from 2005, the airfield was to be closed at the end of 2010 (with the 2014 option). Jet flight operations with the type F / A-18 were terminated in mid-August 2005 for personnel reasons. On December 16, 2005, jet operations in Dübendorf were officially ceased. The last fighter aircraft to land was on April 1, 2016, when the F-5F J-3202 was transferred to the Flieger-Flab-Museum on loan from the Air Force .

Use after the fighter jets have been removed

The decision to close the VBS led to long-term discussions about the future use of the extensive area in a central location in the Zurich agglomeration. In March 2008, the government council of the canton of Zurich informed the DDPS that it expected that the existing option would be used and that the airport would not be closed before 2014. Parliamentarians had already submitted a motion beforehand demanding that the Air Force's deployment concept be reviewed. On May 9th and October 13th, 2008 the DDPS communicated that the location concept for Dübendorf was being reviewed. From 2008 the military airfield was subordinate to the Alpnach airfield command.

In February 2013, the Federal Council declared that, for financial reasons, the runway would no longer be operated for purely military purposes after 2014. The DDPS is looking for a partner who could operate the airfield for 20 years with civil shared use. The DDPS wants to use the airfield only as a helicopter base.

During the discussion time, several interest groups were formed who are committed to the preservation of the airfield in one form or another. Some opponents of the Federal Council's plans fear an increase in air traffic. Other interest groups are calling for the Dübendorf airfield to be retained for further aviation use. The demands range from the entry of the structure plan as aviation infrastructure to the preservation as a cantonal cultural asset of the "oldest civil airfield founded and almost completely preserved former airfield in Europe", if possible even as a UNESCO World Heritage Site , which was rejected by the Federal Council. In the discussion, the government council of the canton of Zurich was generally against the civil use of the airfield with a relocation of business air traffic from Kloten to Dübendorf. The communities also wanted to defend themselves against the noise of the heliport . In June 2015, the Zurich Cantonal Council had not even marked the slope in the cantonal structure plan . At the beginning of September 2016, however, the municipalities of Dübendorf, Volketswil and Wangen-Brüttisellen broke their maximum requirement of no longer allowing aviation at all. But you still don't want any business aviation. To this end, a referendum on an alternative concept was held in the three local communities in November 2017, both according to the president of the FDP local party Dübendorf and the comments in the NZZ against the principles of a legal enactment. Even after approval in all three municipalities, it was unclear how far this could affect the operation planned by the federal government.

Todays use

In September 2014, the Federal Council decided to use the military airfield as a “civil airfield with a federal base”, which would preserve “the federal government's largest strategic land reserve”, and  to enable the canton of Zurich to build an innovation park on the site . The air force will continue to use the airfield as a location during a transitional phase of several years.

The intended triple use consists of

  • the innovation park in the northwest area. The form in which the innovation park , in which a wide variety of companies can rent and which will generate up to 5000 additional jobs, will be built, has yet to be determined. In spring 2017, Aerotrain AG was the first ETH spin-off to move into the existing Hall 3 of the airport. The company is developing a Zeppelin drone. Another three professorships at ETH are planning to set up additional research positions. This overbuilding of the airfield area was judged to be inadmissible by the administrative court of the canton of Zurich in July 2020, which ruled that the cantonal design plan “Innovation Park Zurich” was repealed.
  • a civil airfield for business aviation, historical aviation and maintenance operations on the western (Dübendorfer) side. Scheduled and charter flights are expressly not provided. The Rega 1 helicopter base of the Swiss Air Rescue Service has been located in this area since 2003 . In addition, there is use by police helicopters. Flugplatz Dübendorf AG was selected as the operator of the civil airfield . In 2016, after adapting the aviation infrastructure plan , it was commissioned to build the buildings on the site and to operate them for 30 years. The winner of an architecture competition was announced in November 2017. The start of structural implementation on the civilian Dübendorf side is not expected before 2023.
  • the "Bundesbasis Dübendorf" with the air traffic control center of Skyguide where the civil and military air traffic control services have been brought together under one roof since 2009 , as well as the helicopter (flight operations with Super Puma and Eurocopter EC 635 ) location of the air force on the north-eastern side of Wangen. The federal air transport service and the special aircraft for survey flights of the Federal Office of Topography are also located there. The fixed-wing aircraft Pilatus PC-6 Porter for parachute reconnaissance and PC-7 for training and communication are to be relocated to other military airfields, but apart from Locarno, the field was also the main airport for the PC-7 team . Nevertheless, the Dübendorf federal base will remain an available location for occasional missions of all aircraft (with the exception of fighter jets) of the Air Force, Armasuisse and the FOCA. In the complex is the operational management of the air force with the operations center ( AOC , Air Operations Center ) and competence centers.
Flieger-Flab-Museum

One attraction is the “Air Force Center”, the Flieger-Flab-Museum , which is now on the “civilian” side. From 1983 onwards, Ju-Air, located in the Air Force Center, carried out sightseeing and charter flights from Dübendorf with its Junkers Ju-52 vintage aircraft , which are to be resumed from spring 2021. A replica of the Junkers F 13 was currently being assembled on this site ; The first flight took place on September 9, 2016 , and the aircraft was presented to the public for the first time on September 15.

The University of Zurich and the UZH Space Hub regularly carry out research missions from Dübendorf: These include parabolic flights for research and testing, the AVIRIS-NG missions carried out jointly with NASA and the SkyLab's LNAS project. Regular traffic by large passenger aircraft is not planned.

Special events

Since 1995 the Love Ride Switzerland takes place on the first Sunday in May . The airfield will then be occupied by up to 8,000 motorcyclists. This charity event is held for the benefit of children with muscle problems. On August 5, 2006, a Rolling Stones concert took place in front of 65,000 spectators on the grounds of the airfield , and on August 30, 2008 Madonna performed in front of 73,000 spectators.

The prototype (HB-SIA) of the Solar Impulse solar aircraft made its first flight of 350 meters in length on December 3, 2009 at Dübendorf airfield. The aircraft with a wingspan of 63.40 meters was built in June 2007 in the hangar of the airfield. The largest aircraft that ever landed at Dübendorf airfield was a freighter of the type B-747 with a wingspan of 64.40 meters from Cargolux , which brought the Solar Impulse 1 back to Switzerland from the USA on August 5, 2013 .

In September 2015 launched for the first time on Swiss soil from a large airplane for ZERO-G - parabolic flights . These were carried out on behalf of the University of Zurich for scientific experiments. The very first public parabolic flight in Switzerland with the ZERO-G machine, in which paying passengers could take part without reference to experiments, took off in Dübendorf in October 2016.

On November 22, 2016, the Solar Impulse 2 was dismantled in Abu Dhabi, loaded into the hold of a Boeing 747-400 from Cargolux and taken to the Dübendorf military airfield. The Solar Impulse 2 is stored at the Dübendorf military airfield until further notice.

From March 19, 2020, short and medium-haul aircraft from Swiss , Edelweiss Air and Helvetic Airways were parked at the Dübendorf military airfield due to the coronavirus crisis .
