MAX77 The German military used Fornebu heavily during the war, but it was never of any strategic importance, since it was located far from any battle zones. By orders of the German authorities, the main north-south runway was expanded to 1,200 m (3,900 ft), and all facilities not yet built were completed. There was no attempt by the civilian airport authorities to hinder this, such as driving cars onto the runway, although several German aircraft collided with each other during the landing. At the north end of the runway, the Luftwaffe built several hangars and a prison camp. However, during the war all other runways than the main north-south were taken out of use. Prisoners were used to keep the runways free of snow during winter, by marching along them and stomping the snow down. On 12 April, the airport was bombed by the British Royal Air Force. None of the civilian airlines were in operation, and the Air Force started flying commercial flights.|Kamen Rider Cross-Z (Karakter)
