Munich Airport reopened on Saturday after German authorities shut it down the night before for the second time in less than 24 hours after more suspected drone sightings. The closures are the latest after mysterious drone overflights in the airspace of European Union (EU) member countries. The airport, one of Germany’s largest, reopened gradually, beginning at 7am local time on Saturday. At least 6,500 passengers were impacted by the overnight closure Friday into Saturday, the airport said.
