The skies were blue and sunny, the runways clear of snow and ice, and traffic should have flowed routinely through Oslo’s main airport at Gardermoen (OSL) on Thursday after a rough winter. Instead, the airport was forced to close on a busy spring afternoon, because of a mysterious aircraft that entered its air space and stayed there.
Officials were still unsure Friday morning who was behind the problem that forced aviation officials to redirect all incoming flights for nearly two hours on Thursday, because a small unidentified aircraft resembling a hang-glider or sail plane hovered at 8,000 feet in the middle of the airport’s landing patterns.
As many as 15,000 passengers had their plans ruined, because their flights were sent off to land at outlying airports like Torp and Rygge, or even as far away as Fagernes and Stockholm. Either they missed onward connections from Gardermoen, or wound up far away from their intended destinations. And the lack of incoming aircraft hit departures hard, too.
