cancelled, it was the last remaining domestic service in the Netherlands. An ILS system, which allows landings in poor weather, was built in 1967, for runway 22 only. 1970s In 1973, the airport was expanded again to handle bigger aircraft. The main runway was lengthened to 2500 m (8,200 ft), taxiways were widened, and aprons were enlarged. This mostly offset the negative effects of the 1973 oil crisis, passenger volume remained the same and cargo operations expanded. The international air traffic control area control centre for EUROCONTROL was built at the airport. It started operations on March 1, 1972. 1980s Around 1980, the airport changed its name to "Maastricht Airport". In 1983, the aging passenger terminal and air traffic control tower were replaced by new buildings The new terminal was later expanded and is still in use as of 2010. On 14 May 1985, Pope John Paul II held an open-air mass for 50,000 people at the airport, as part of his visit to the Netherlands. Plan for an east–west runway In 1981, a development plan for the airport recommended constructing a 3,500m east–west runway to facilitate growth in cargo operations, particularly during the night hours. The new runway would greatly reduce noise impact over the towns of Beek, Meerssen and the city of Maastricht. Although some night operations are allowed (including distribution of the European edition of The Wall Street Journal), runway length limits intercontinental operations. The Dutch government initially approved plans for the runway in 1985, however, the new runway would mean increased noise over other towns and parts of Belgium as well, and the final decision was delayed. As the new east–west runway would require substantial investment, it would only be profitable if night operations were permitted and increasingly the debate became focused on whether or not night flights should be allowed. Successive cabinets could not reach a final decision, and in 1998, after some 25 years of debate and postponement, the plan was aborted altogether. 1990–2009 In 1992, the Belgian town of Tongeren became shareholder of the airport. Two years later, the board of trade or chamber of commerce of the nearby German city of Aachen became shareholder. This interest eventually became prominent and in October 1994 the airport's name was changed to "Maastricht-Aachen Airport". In July 2004, a 100% share in the airport was acquired by OmDV, a consortium of airport investment company Omniport and
