Air traffic at Munich Airport was suspended for about an hour on Saturday morning following a suspected drone sighting.
Take-offs and landings were halted shortly after 9 am (0700 GMT), but the alert was lifted at around 10:15 am, a spokesman for the German airport said.
A police spokesman said two pilots had reported a suspicious sighting, prompting an investigation involving a police helicopter.
After the investigation found nothing, the closure was lifted and air traffic resumed, the airport spokesman said.
