The drone was found shortly after both runways at the major cargo hub were closed late Tuesday following reports of a flying object near the airport. German Interior Minister Alexander Dobrindt, who cut short his vacation to visit the airport, described the incident as an unprecedented escalation. "That the drone was carrying explosives is a new quality of danger." "Drone sightings, drone threats including in a hybrid context, are something we know from the past." Police said another flying object apparently struck a cargo aircraft after it aborted its landing because one runway had been closed.
