there, along with the main radar center. All the terminal buildings built until the early 1960s were still intact until the closing of the airport. In 1989, about 5,500 people worked at Fornebu. Of these, 3,600 worked for the airlines, including ground services. The airport administration had 350 employees, including administration, air control, fire fighters, meteorology and maintenance. The remaining 500 people worked for other public offices, including the police and customs, as well as service employees working for private companies involved with passenger services. Fornebu had two runways: a main east–west runway and a secondary north–south. Only the main runway was used under ordinary weather conditions, with the north–south runway only being used if there was strong winds from the north and for general aviation, helicopters and ambulance aircraft. The main runway was equipped with instrument landing system category 1. Under ordinary weather conditions, flights to Fornebu were to, as soon as possible, divert southwards along the Oslo Fjord to avoid noise pollution to residential areas. However, when necessary, a direct approach could be made eastwards from Drammen or westwards from Grefsenåsen. Until 1996, Oslo Air Traffic Control Center (Oslo ATCC) was located at Fornebu. It had the responsibility to oversee all air traffic in southeastern Norway, bordering to Dovre in the north, almost to Stavanger in the west, halfway to Stockholm to the east and almost to Denmark in the south. Since Fornebu is located on a peninsula, all transport to the airport needed to go via Lysaker. A branch from the motorway European Route E18 allowed access to the airport. Lysaker Station is on the Drammen Line, and was served by both local and regional trains, including services to Oslo Central Station. In addition, Stor-Oslo Lokaltrafikk offered bus transport to the airport from Asker and Bærum, including Lysaker. A limited number of services were extended to Snarøya. An airport coach connected the airport to the city center. Airlines and destinations In 1996, the airport had 170,823 aircraft movements and 10,072,054 passengers, making it the busiest airport in the country. It served as the main hub for Braathens SAFE, one of three main hubs for SAS and as one of many for Widerøe. Prior to 1 April 1994, all air transport in Norway was restricted to airlines that had received concession from the ministry. On the primary domestic routes, the traffic was split between SAS and Braathens SAFE,
