Flights were disrupted when a UFO appeared on radars at a German airport, police have said, reports Euronews.
The unidentified aircraft cancelled one flight, diverted another and caused delays at Bremen airport.
The airport said the UFO showed up on its radar several times between 16h30 and 21h30 local time.
Police, who scrambled a helicopter to investigate, admit they still don’t know what the object was.
The incident cancelled a flight from Frankfurt, while another from Munich was diverted to Hanover.
A similar incident in Saxony on Sunday turned out to be a remote-controlled model airship.
