Airspace closure in Norway causes flight delays at Oslo Airport.

A technical problem made Norway close the south part of its sky for a little while. This caused a lot of waiting at Oslo airport, a big airport in Scandinavia.

After more than three hours, they started to let planes fly in the sky again. But, there were still going to be delays for the rest of the day.

The problem was at a place called the Oslo Control Center. This made it hard for planes to fly in the southern part of Norway.

They said they would let the very long flights go first. But it was going to take a lot of time to get back to how things were before.

Oslo's airport is a very busy place with lots of people flying from there. A company named Avinor takes care of this airport and many others in Norway.
